If something is wrong with the Geely MK Cross, then "Check-Engene" does not go out, or it lights up again after a while. It can also blink, which clearly indicates a serious malfunction. This indicator will not tell the Geely owner what the problem is, it draws attention to the fact that a Geely MK Cross engine diagnosis is required.
Since all foreign cars, not excluding the Geely MK Cross, are tightly tied to electronics, a huge number of sensors monitor the operation of the car. Therefore, diagnostics of the Geely MK Cross engine is, by and large, checking the most important unit of the machine, with the exception of the suspension, which is checked mechanically.
There is a large number of specialized equipment for diagnostics of the Geely MK Cross engine. There are compact and fairly versatile scanners that not only professionals can afford. But there are times when ordinary portable scanners do not detect malfunctions in the Geely MK Cross engine, then diagnostics must be carried out exclusively with licensed software and a scanner from Geely.
Geely Diagnostic Scanner Shows:
- Throttle valve opening percentage;
- Engine speed in rpm;
- Geely MK Cross engine temperature;
- Voltage in the Geely MK Cross on-board network;
- The temperature of the air sucked into the engine;
- Geely MK Cross ignition timing;
- Fuel injection time by the injector. Displayed in milliseconds;
- Readings of the Geely MK Cross air flow sensor;
- Oxygen sensor readings Geely MK Cross;
1. To diagnose the Geely MK Cross engine, first of all, the engine compartment is inspected visually. A serviceable engine should not have any leaks of technical fluids, be it oil, coolant, brake fluid. In general, it is important to periodically clean the Geely MK Cross engine from dust, sand, dirt, this is necessary not only for aesthetics, but also for normal heat dissipation!
2. Checking the oil level and condition of the Geely MK Cross engine, the second step of testing. To do this, you need to pull out the dipstick, and also look at the oil by unscrewing the filler cap. If the oil is black, and even worse black and thick, then this indicates that the oil has changed for a long time.
If there is a white emulsion on the filler cap or you can see how the oil foams, then this may indicate that water or coolant has entered the oil.
3. Checking spark plugs Geely MK Cross. Remove all plugs from the engine; they can be checked one at a time. They must be dry. If the candles are covered with an insignificant layer of yellowish or light brown carbon deposits, then you should not worry, such carbon deposits are quite normal and permissible, and do not affect the work.
If there are traces of liquid oil on the Geely MK Cross candles, then the piston rings or valve stem seals are likely to be replaced. Black carbon deposits indicate an over-enriched fuel mixture. The reason is improper operation of the Geely fuel system, or a too clogged air filter. The main symptom will be increased fuel consumption.
Red plaque on Geely MK Cross spark plugs is formed due to low-quality gasoline, which contains a large amount of metal particles (for example, manganese, which increases the octane number of the fuel). Such a plaque conducts current well, which means that with a significant layer of this plaque, the current will flow through it without forming a spark.
4. The Geely MK Cross ignition coil does not often fail, most often this happens due to old age, insulation is damaged and a short circuit occurs. It is better to change the coils in accordance with the mileage according to the regulations. But it happens that a breakdown is caused by bad candles or punctured high-voltage wires. To check the Geely coil, it must be removed.
After removal, you need to make sure that the insulation is intact, there should be no black spots or cracks. Next, a multimeter should go into the course, if the coil is burnt out, then the device will show the maximum possible value. It is not necessary to check the Geely MK Cross coil by the old-fashioned method for the presence of a spark between the spark plugs and the metal part of the car. This method takes place in old cars, while on the Geely MK Cross, due to such manipulations, not only the coil can burn out, but also the entire electrics of the car.
5. Is it possible to diagnose engine malfunction by smoke from the exhaust pipe of Geely MK Cross? Exhaust can tell a lot about the condition of an engine. In the warm season, no thick or bluish smoke should be visible from a serviceable car.
If white smoke is visible, then this may indicate a burnt-out gasket or leakage in the Geely MK Cross cooling system. If the smoke is black, then at best these are problems due to an over-enriched fuel mixture. At worst, problems with the piston group.
If the smoke has a bluish tint, then this indicates that the Geely MK Cross engine uses oil. In the best case, replacement of the valve stem seals will be required, in the worst case, the repair of the piston group. All this fumes greatly clog and shorten the life of the Geely MK Cross catalyst, which cannot cope with the purification of such impurities.
6. Diagnostics of the Geely MK Cross engine by sound. Sound is a gap, this is what the theory of mechanics says. There are gaps in almost all moving joints. This small gap contains a film of oil that prevents parts from touching. But over time, the gap expands, the oily film can no longer be evenly distributed, friction of the parts of the Geely MK Cross engine occurs, as a result of which very intense wear begins.
Each node in the Geely MK Cross engine has a specific sound:
- A loud, frequent sound heard at all engine speeds indicates the need to adjust the valves;
- An even knock, which does not depend on the speed, is caused by the valve-distributor mechanism, which indicates the wear of its elements;
- A distinct short knock, increasing at higher revs, warns of the imminent end of the connecting rod bearing.
7. Diagnostics of the engine cooling system Geely MK Cross. With proper operation of the cooling system and sufficient heat dissipation, after starting the engine, the liquid circulates only in a small circle through the heater radiator, which contributes to the rapid warming up of both the engine itself and the Geely MK Cross interior in the cold season.
When the normal operating temperature of the Geely MK Cross engine is reached (about 60-80 degrees), the valve opens slightly, i.e. the liquid partially flows into the radiator, where it gives off heat through it. In case of reaching a critical mark under 100 degrees, the Geely MK Cross thermostat opens to the full, and the entire volume of liquid passes through the radiator.
Together with this, the fan of the Geely MK Cross radiator turns on, it contributes to better blowing out of hot air between the radiator cells. Overheating can damage the engine and require costly repairs.
8. Typical malfunctions of the Geely MK Cross cooling system. If the fan does not work when the critical temperature is reached, then first of all it is necessary to check the fuse, then the Geely MK Cross fan itself and the integrity of the wires to it are examined. But the problem may be more global, the temperature sensor (thermostat) may have failed.
The performance of the Geely MK Cross thermostat is checked as follows: the motor is preheated, a hand is applied to the bottom of the thermostat, if it is hot, then it is working properly.
More serious problems may arise: a pump failure, a leak or clogging of the Geely MK Cross radiator, a broken valve in the filler cap. If problems arose after replacing the coolant, then most likely an air lock is to blame.
Hello, your question is under development. It will take some time for an accurate answer. Thanks for waiting.
Balakovo, LADA (VAZ) 2108
Hello.
There are two likely causes of this problem:
1. Clogged fuel or air filter (or both),
2. Defective (worn out) spark plugs.
First, you should check and, if necessary, replace the filter and spark plugs.
Also, the reasons may be:
1. Poor quality fuel - you should try to refuel at another gas station,
2. Low-quality (waste) oil - check the condition of the engine oil for impurities,
If the above measures do not lead to the desired result, then it is necessary to carry out computer diagnostics of the engine.

Answer article
Hello, in fact, there can be a lot of reasons, and we have listed them for you above. But I would leave the ignition angle at the end of the list, since it can give similar symptoms, but it obeys the program, and there is nothing to break there, since the angle itself is a programmed value. But the failure of the sensors can knock him down. But there is another problem with starting the car, which the angle will definitely not affect. For example, a malfunction of the nozzles or the pressure regulator can give a large enrichment of the mixture, which will lead to poor starting and afterburning of the mixture in the exhaust manifold (pops). But any other sensor, such as an air or engine temperature sensor, can mislead the ECU and there may be such symptoms. You need to find a good diagnostician who will connect your car to the scanner and check all the parameters while driving and in those moments when it does not start. He will check how the mixture burns, what is the injection time, if there are deviations, he measures the pressure of the fuel system. It is advisable to connect a 2-beam oscilloscope, to DPKV and DPRV, checking their operation and at the same time the correspondence of the timing marks. It is also important to check the injectors at the stand for spillage and tightness. Without such manipulations, the diagnosis turns into fortune telling on the coffee grounds.

The main key parameter is an intelligent diagnostician, or an electrician, but it will take him a lot of time to check everything manually, computer diagnostics simplifies this process at times.
Sumy, Peugeot 605
I agree with all of the above.
But start with the accessible. Change filter, fuel, air. Replace spark plugs with high voltage wires. Measure the compression in the cylinders at the engine operating temperature. After the results obtained, decide on a trip to a car service. Thus, reduce the costs of being at the service station.
Odessa, Mercedes-Benz E-Class
And sometimes when you go abortions rise to 2.5 tons to 3 tons. And in order for them to fall, you need to gas a couple of times before the cutoff! And if at this moment you turn off the engine, it will not start again!
Grozny, Geely MK
Do you mean idle speed? Are they not falling? Then this is a problem of the idle speed regulator (throttle assembly), but this requires verification, since there is a possibility that this is an incorrect command from the controller, and not mechanical jamming is to blame. This can be accurately determined at the time of manifestation by checking the current readings and checking the operation of the throttle, operating it from the scanner in the actuator control mode.
Moscow, Chrysler Voyager
I changed reg. idle move!
For many car owners, this problem is really difficult to solve. The engine trots and runs unstable, what could be the reasons? There can be several reasons, of course ... But for some reason, when you say to people: “ change the candles first“, They answer me: yes, the candles were changed recently. Unscrew them again and watch!
One more BUT: I strongly advise against going for diagnostics if your car has a troit engine. Why? Will explain:
Diagnostics in most car services (not in all, thank God) means connecting a scanner and reading error codes. That is, they will connect a scanner to the machine, count errors and take money from you 😀 And if there are no errors? They will take the money anyway, because the scanner was connected 🙄 At best, the device will give an error: Ignition misfire in any cylinder.
Well, here it is already easier if it is one specific cylinder, the search area is narrowed. But again, the service may tell you that diagnostics is one thing, but repair or troubleshooting is completely different and you need to pay for it separately.
What to do in such a situation? Before entering the service, ask what they have in the concept of "diagnostics" and how all this is paid. I have an article on what to read after reading this article.
Consider the reasons why the engine is troit
First thing to check: Spark plugs
Candles
Unscrew them and look at the soot at their condition. First, it leaves a lot to be desired. Defective spark plugs may leak current through cracks on the insulator.
Carefully inspect the insulator itself, whether there are characteristic thin light stripes on it, these stripes are traces of a spark when it stitches in the wrong place. In addition to obvious problems with candles, there may be a too large or small gap between the electrodes.
High voltage wires
Following the candles, they fall under suspicion high voltage wires or candle tips... Examine them carefully for breakdown. Black spots with carbon deposits or stripes with carbon deposits are a trace of a spark breakdown in this place. Accordingly, the spark simply does not reach the spark plug and the engine triple starts.
Ignition module
If the engine is cold, and the candles and wires are in order, be sure to check ignition module... Remove the wires from the candles on a running engine one by one (just carefully and do not take them far from the candle), you can hear the sound of breaking the air gap between the candles and the tip of the wire. If the sound of a spark is not heard in all cylinders, then the module is most likely defective.
Attention:
This method is dangerous. If you pull the tip too far away from the spark plug, you will either get an electric shock, or the module or engine control unit may burn out. Because in the absence of load, the ignition module or the control transistors in the control unit burns out.
Fuel mixture
Another reason why the engine is troit is. In such cases, the engine simply floods with gasoline and the candles periodically refuse to work. When diagnosing the scanner, the error code P0172 - rich mixture may appear.
Timing marks
Attention:
Among other things, timing marks on the engine may be knocked down or incorrectly installed. In this case, the engine works unstably and seems to be troit, but there is a spark everywhere and the fuel flows normally.
Crankshaft sensor
Unlike labels with crankshaft position sensor malfunction (for example, turn-to-turn circuit) the motor is unstable. It may happen that the engine troit at rpm above 2000. And it is not always that when a coil occurs in the sensor, the control unit receives an incorrect signal about the position of the pistons and gives a spark at the wrong moment when it is needed. In addition to the spark, the injection moment is also violated. The impulse from the crankshaft sensor can be violated if the distance between it and the reluctor wheel is not correct (usually 0.8 -1.2 mm).
Defective injectors
Damage or incorrect operation of injectors can also be the cause of triple formation. If you have checked the presence of a spark on all cylinders and there is a spark, then you can check the operation of the injectors. By alternately removing the connectors from them, you can find out which cylinder does not work. But not the fact that the nozzle is to blame, maybe a candle after all. Without equipment, you can only check by changing the nozzles in places. If after changing the injectors another cylinder does not work, then the injector has "died"
Compression
Low compression in the cylinders can also be the reason that the engine troit. Poor compression can be caused by stuck O-rings or burnt valves. Such a malfunction is checked by measuring the compression. Also, if the valves on your machine are adjustable, then the reason may be incorrectly set clearances. If there are hydraulic lifters, they can also be the reason.
Attention:
Often people contact the service with a problem: the engine is troit. And at the same time on the dashboard the lamp "check engin" or "jackie chan", as I sometimes call it, usually lights up. I want to explain a little to you what the lighting of this lamp can mean when the motor is unstable.
If the lamp starts to blink it means that the control unit has detected misfire in the cylinders and in order to avoid damage to the catalytic converter, it warns you of a malfunction. Computer Diagnostics in this case is unlikely to help you, all that the scanner will say: "Misfire detected," that is, the engine is troit. But we can see this even without him.

Geely MK 1.5 4dv. sedan, 94 HP, 5MKPP, 2008 - engine troit
The main reasons for triplet
Incorrect ignition timing.
- Air leaks in the brake vacuum booster system.
- Faulty spark plugs. It is worth noting that this problem is the most common, since the spark plugs need to be changed after the vehicle has traveled every 20,000 kilometers (this figure depends on the recommendations given by the designers to each vehicle).
- Breakdown of the high-voltage wire that fits the spark plug.
- Faulty installed capacitor.
- Violation of the tightness of the system in the area of \u200b\u200bthe intake manifold.
- The appearance of burnout of one of the piston, valve.
- Piston ring breakage, deformation and wear also lead to this problem.
- Incorrect adjustment of the valve timing.
- High degree of wear on the rocker.
- Breakdown of the installed cylinder head gasket.
- Any kind of wear (hardening, breakdown, destruction) of the valve stem seals.
- If the carburetor is incorrectly adjusted, cylinder malfunction can also occur.
- Condition of the installed distributor shaft, pivot plate bearing.
- Clogged air filter.
- Loss of tightness of the membrane of the vacuum ignition timing regulator.
- The use of unsuitable spark plugs (not only the dimensions are taken into account, but also other parameters of this element) for this engine.
Engine troit
Engine structure is a definition by which one should understand a failure in the operation of an internal combustion engine, when one or more cylinders do not work partially or completely. In other words, the combustion process of the fuel-air mixture in individual cylinders is disrupted, which causes unstable operation of the engine at idle, under load and in transient modes.
The structure of the engine manifests itself in the form of increased vibrations of the power unit, the engine noticeably loses power. Ignition misfires can be observed, which are accompanied by strong popping in the exhaust system. The motor can run both occasionally and constantly, only at idle or under load, on cold, on hot, etc. Next, we intend to answer the question of what is engine triplet, and also consider the main reasons why the motor begins to triple.
Why does the motor start to triple
The engine trot is a violation of the combustion of the mixture in the cylinders, which is accompanied by a clear increase in vibration. Please note that the appearance of vibrations of the internal combustion engine is not necessarily a triple, as there are a number of other reasons why the engine vibrates strongly.
In the list of major faults, as a result of which the engine troit, the following are noted:
Insufficient or excess fuel supply to the cylinder;
insufficient or excess air supply;
malfunctions of the ignition system, early or late ignition;
engine wear or breakdown, which is accompanied by a decrease in compression;
In other words, the engine begins to triple as a result of an inappropriate composition of the fuel-air mixture, untimely ignition of the mixture or the inability to ignite the charge, as well as violations of the conditions for normal combustion of the mixture as a result of mechanical wear or breakdowns of the engine itself.
Based on these data, it is possible to narrow the search and the number of systems for diagnostics. The test should start with the fuel system and injector, then the intake air supply and ignition system are checked. In some cases, engine tripping may also be the result of a failure of one of the ECM sensors.
The engine is troit: the ignition of the fuel-air mixture is broken
The most common cause that causes the engine to triple is late or early ignition, as well as a weak spark from the spark plug. At the initial stage, the spark plugs should be unscrewed for a detailed inspection. If damage to the insulator or other defects is noticeable, then the spark plug should be replaced.
In the case of a damaged insulator, the place of damage is clearly visible, since this area turns black. You should also pay attention to the condition of the center electrode and evaluate the clearance of the side electrode.
Next, you need to check the spark plug wires. An indirect sign indicating this element is the occasional tripping of the motor in conditions of high humidity (rain, dampness, etc.). After warming up and reaching operating temperature, the symptoms may completely disappear.
You should start by inspecting the candle cap and the high-voltage wire itself. These elements have rubber insulation, which tends to dry out and crack over time, as a result of which the wire begins to break through.
Also, the high-voltage wire or cap is often damaged during service or repair work in the engine compartment. We add that the place of the breakdown can be visually undetectable. In this case, it is better to check this element of the ignition system using one of the available methods.
If everything is in order with the candles and wires, then the ignition coil may be the culprit for the engine troit. On motors with separate coils for each candle, this phenomenon is especially common. To check the ignition coil, it is necessary to unscrew the spark plug, apply it to the ground and start the engine. Please note that the thread of the candle should touch the mass tightly, the cap should be tightly put on the candle. Failure to follow these guidelines can result in burnout of the coil or switch. A good spark with a characteristic crackle will indicate that the coil is working, the absence of a spark will indicate the need to replace the coil.
As for the electronic ignition distributor (switch), this element does not break often. To check, the candles are securely attached to the ground, then the caps are connected to them, after which one person turns the motor with a starter, and the other assesses the strength of the spark on the candles.
Motor structure: air supply problems
Insufficient air supply at the inlet or an excessive amount of it can also cause tripping over the cylinders. The air supply system can lose its tightness and the engine begins to suck in excess air. The ECU does not take into account this leakage, as a result, the stability of operation is disturbed.
Checking the air system is straightforward. It is necessary to tightly close the inlet pipe next to the air filter, then pump air to create a pressure of about ½ atmosphere, and then look for the leak. If the pressure does not drop, then the system is sealed. The appearance of a hissing sound of outgoing air allows you to determine the problem area through which the motor sucks in excess.
Air shortages are often caused by a dirty air filter that has lost its capacity. The filter must be removed and the engine performance evaluated after removal. Also, there may be insufficient air in the event that the throttle valve is clogged or there is a problem with this unit. The specified element requires mandatory cleaning and inspection. It is advisable to do this at each scheduled maintenance in parallel with the replacement of engine oil, filters, etc.
Another reason for the triplet engine may be the DPDZ, DMRV or another sensor that gives the wrong signal to the ECU. In such a situation, the control unit does not know to what degree the damper is actually open, how much air actually entered the engine, etc. On the basis of incorrect data, the "brains" cannot accurately calculate the optimal composition of the fuel-air mixture in relation to the dynamically changing operating modes of the internal combustion engine.
In this case, you should view the readings of the sensors and read the errors with a scanner that is connected to the diagnostic connector of the car. Then the values \u200b\u200bmust be compared with the nominal values. Abnormalities in the readings of the air flow meter or throttle position sensor lead to the fact that the engine begins to triple.
Driving over cylinders: power system faulty
When checking the power system, you should pay attention to the following nuances:
Fuel pressure;
air leaks;
Fuel pressure directly depends on the health of the electric fuel pump, which is located in the fuel tank on modern injection cars. The device may have a clogged fuel pump filter mesh, there may be problems with the fuel pump electric motor or the power supply to the pump. It is also worth checking the fuel rail pressure regulator valve. Low pressure in the fuel supply system is often the cause of triplet.
The next step is to check the injection nozzles. This element tends to clog, as a result of which the throughput decreases, the shape of the spray pattern is disturbed, etc. Also, the failure of the nozzle itself should not be ruled out. To clean and check the nozzles, you can use a flushing stand, on which a special flushing liquid is pumped through the device and power is supplied. In such conditions, the operation of the injector on the engine is simulated, the performance is evaluated, etc.
You can also check and clean the nozzles yourself. For this, a liquid is also pumped through the device (for example, a carburetor cleaner). Power is supplied through a simple circuit with a light bulb from the battery terminal.
A working injector should not leak when closed. Also, the injector must open in a timely manner when an electrical impulse is applied. The injector is not allowed to pour fuel, since the efficiency of the subsequent combustion of the charge in the cylinder depends on the quality of the spray.
If the fuel pressure and the injector itself are in order, then the ECU should be checked. The control unit itself rarely fails, but it is possible. More often this happens in those cases when the factory firmware was changed when installing HBO or the engine was done with software chip tuning. Unprofessional manipulation of fuel cards can lead to the fact that the ECU overflows fuel and fills the spark plugs.
Reduced compression in cylinders
Loss of compression indicates engine malfunction or wear. One or more cylinders are partially or completely not working, so fuel and air are supplied, but the mixture is not compressed properly. In this case, normal combustion does not occur. A drop in compression occurs due to burnout of pistons or valves, severe wear of piston rings and other defects of the BC, cylinder head or timing elements.
In this case, it is necessary to measure the compression in the engine, after which the unit is disassembled for detailed diagnostics and repair. In conclusion, I would like to add that the operation of a motor with an inoperative cylinder is prohibited, since driving with such a malfunction leads to a number of additional problems, which greatly complicates and makes subsequent repairs more expensive.
Specifications
Specifications Geely MK 1.5 / Geely M-Kay in the back of 4 doors. sedan with 94 hp engine, 5MKPP produced since 2008
Geely MK is a Chinese representative of the small class. When it was developed, the first generation Toyota Vios was taken as a basis, which in turn is nothing more than the redesigned first Toyota Yaris. This explains the almost complete similarity of the chassis with the Yaris of 1999-2002, and the 1.5 liter engine is a licensed copy of the Toyota 5A-FE.
Geely MK appeared in Russia in June 2008. The first Geely came to salons straight from China. Since 2010, Geely MK has been assembled in Cherkessk, at the Derways enterprise.
Engine
Geely MK engine has a timing belt drive. From experience, the condition of the belt does not interfere with checking after 40-50 thousand km. Some of them do not show the slightest signs of wear for 60,000 km, while others may be missing a pair of teeth, and the belt is covered with cracks. Fortunately, when the belt breaks, the valves do not meet with the pistons. When replacing the timing belt, the right engine mount must be removed.
During a cold start, the Geely MK motor often starts to "triple". The problem can be solved after replacing the spark plugs, high-voltage wires, ignition coils (1,000 rubles) or adjusting the valves. When removing high-voltage wires, owners often tear them off. Neglect of adjusting the valves is fraught with their "clamping" with a run of more than 40-60 thousand km and subsequent burnout. Burnout is more common on cars with HBO installed.
The gasket on the throttle heating begins to leak antifreeze over time. When the coolant dries up, it contaminates the idle speed regulator channel and the regulator itself. The result is a difficult start, the engine stalls immediately after setting and starts only with the gas pedal depressed. To prevent leakage, after cleaning the channel, it is better to put the throttle gasket on a heat-resistant sealant. A native new idle speed regulator costs about 1,000 rubles, an analogue for a Chevrolet Niva for 500 rubles is suitable as a substitute.
The Geely MK motor is prone to overheating in the warm season when driving for a long time at a speed of more than 100 km / h with the air conditioner on. The problem appears when the mileage is more than 40-50 thousand km. One of the reasons is that the cooling fan does not work due to poor contact at one of the three points of the ground wire. Also, the cause of overheating can be the late opening of the thermostat and the peculiarity of the operation of the motor ECU, which gives the command to turn on the fan even at critical values \u200b\u200bof the coolant temperature. The coolant temperature sensor itself may give incorrect values \u200b\u200bdue to acidification of the contact terminals. "Underheating" or a long warm-up of the engine indicates acidification of the thermostat in the open position, which is also not uncommon. A new thermostat costs about 200 rubles.
Some owners are faced with the need to replace a burnt-out cylinder head gasket. The liquid cooling pump of the engine may fail with a mileage of more than 50-100 thousand km. The appearance of rusty stains in the expansion tank causes confusion. In cold weather, cooling radiators often leak at the junction of plastic with metal.
The O-ring of the exhaust system at the junction of the exhaust manifold with the pipe often has to be changed due to burnout. With a mileage of more than 80-120 thousand km, the front crankshaft oil seal begins to leak. The oil pressure sensor can fail with a mileage of more than 50-60 thousand km.
The rear engine support travels more than 40-60 thousand km, after which it begins to knock. The new support will cost 1.5-2 thousand rubles.
After 150-200 thousand km, oil consumption often increases. It is not always possible to eliminate the oil scraper just by replacing the valve stem seals. Often, buried rings are to blame. A set of rings and caps is available for 4,000 rubles.
Transmission
The 5-speed "mechanics" on the new Geely MK suffers from poor gear shifting for the first few thousand kilometers. After the elements of the box "roll in", and there are no problems with the ease of shifting gears. A considerable contribution to the poor speed selectivity is made by the "cheap" oil, poured into the box even during assembly. Such a "transmission" thickens strongly in the cold. After changing the working fluid, the operation of the box improves.
With a mileage of more than 50-70 thousand km, the box starts to make noise. The reason is the wear of the bearings of the input and output shaft. It is noteworthy that in the warranty booklet the box bearings are spelled out as a separate item, and the warranty for them is only 30 thousand km. For the work on removing and installing the box, you will have to pay about 3 thousand rubles, for the bulkhead - about 4 thousand more rubles, a set of new bearings will cost 1-2 thousand rubles.
The clutch takes care of more than 90-120 thousand km. A new set with a basket and a release bearing will cost 3-5 thousand rubles. With a mileage of more than 100,000 km, the box often starts to make noise when the gas is released in third gear.
Drive oil seals can leak after 30-40 thousand km. The cost of the drive oil seal is about 500 rubles. After 50-60 thousand km, it may be necessary to replace the clutch master cylinder. A leaking cylinder can be restored using a repair kit for 600 rubles.
The anthers of the outer CV joint will most likely have to be replaced when the mileage is over 100-120 thousand km. The original anthers cannot be found separately, as they are sold only assembled with the drive. But it will not be difficult to find an analogue in the store of spare parts from other car brands.
Chassis
The Geely MK suspension is not particularly durable. The front stabilizer struts are the first to surrender - after 20-30 thousand km. The stabilizer bushings run a little longer - about 40-60 thousand km. Shock absorbers can leak or knock after 30-60 thousand km. The cost of a new one is in the range of 1.5-2.5 thousand rubles. Front wheel bearings serve more than 60-80 thousand km. Ball and suspension arms go the same. A new ball one costs about 800 rubles.
Due to the "curve" of the assembly, the steering rack has a lateral play that can be removed after pulling up. Often the rail begins to leak after 50-100 thousand km. The cost of a new rail is about 15-20 thousand rubles. Steering rods and tips run more than 50-80 thousand km. Sometimes the power steering pump also fails.
Due to corrosion of the coating of the piston of the brake cylinder of the front caliper with a mileage of more than 50-70 thousand km, the brakes can wedge. The repair kit will cost 400 rubles. Sometimes the rear brake cylinders begin to "poison" the brake fluid.
Body and interior
The body of Geely MK does not resist corrosion well. The first foci will inevitably appear on the chips. And after 1-2 years of operation, in the lower corner of the front doors under the seal, in the area of \u200b\u200bthe trunk lid lock, the fuel filler flap and on the inner surface of the hood. Later, wheel arches and sills begin to rot. Sill corrosion is most susceptible to cars with a factory hatch. The engineers brought the hatch gutters directly into the thresholds. Over 30 thousand rubles will have to be paid for the repair of the thresholds.
The headlights and taillights often fog up, and the fog lamps often burst when used in cool, damp weather.
The hard plastic of the Geely MK interior is very squeaky, especially in cold weather. The rattling in the steering wheel can occur due to the screws that loosen over time that hold the airbag assembly. A loosely installed steering shaft seal allows engine and exhaust noise into the passenger compartment.
One of Geely MK's problems is the water in the cabin. It gets there because of poorly glued windshield and rear windows, as well as through flying rubber plugs on the bottom. Water accumulates in the trunk due to the rear light seats and rear shock absorber mountings. Water can also enter through the ventilation valves.
The work of the air conditioner also raises a lot of complaints. The air conditioner becomes ineffective when the ambient temperature is more than 25-30 degrees Celsius. This is facilitated by the design feature of the heating system: hot pipes and a heater radiator are located directly under the panel. Even in cool weather with the air conditioner turned off and the temperature controller in the cold sector, warm air flows from the deflectors.
With more than 100,000 km of travel, leaks in the air conditioning system are found more and more often. The air conditioner compressor (about 9-12 thousand rubles) can jam after 50-100 thousand km. The heater fan sometimes stops turning on or changes the rotation speed due to the failure of the relay (rheostat) of the fan speed controller. The new regulator is not expensive - about 400 rubles.
Electrical equipment
Problems with the charging current may appear after 80-120 thousand km. The reason is the failure of the voltage regulator. A set of a new relay and brushes will cost 2.5-3.5 thousand rubles. A new generator costs about 4.5-5.5 thousand rubles.
Due to the closure of the temperature sensor of the seat heating element or the "sticking" of the heating activation button, the heating of the front seats may stop working. Factory heating elements for heating mirrors do an excellent job, but they often fail. After replacing the mirrors with an analogue, the heating becomes not so effective, but much more durable.
If the mileage is more than 100-150 thousand km, the steering column cable may break. There are frequent problems with the dashboard illumination. The reason is the failure of the microcircuit of the driver board of the electric motors that control the movement of the arrows and the illumination of the devices. The cost of a new device is about 7-8 thousand rubles.
Conclusion
The quality of Geely MK, produced at home in China, and here, in Russia, is significantly different. Chinese Geely are assembled more soundly - all elements of the body and interior fit well, and the gaps are even everywhere. Domestic assembly, on the contrary, is famous for poor fit of body parts and always under-tightened or torn off bolts. But there are also disadvantages of Chinese cars - the ECU firmware does not cope well with starting in cold weather, a software update is necessary. In addition, in Chinese Geely, electrical problems are not uncommon due to oxidation of contacts made of low-quality brass.
Another problem that you have to face is the complexity of the selection of spare parts. There may be completely different parts under the same number that are not interchangeable with the original. Either they shoved everything that was at hand into the car during assembly, or problems in catalogs ... The only way out is to take a faulty unit (part) with you and compare the similarities by eye.
