Changing the oil in the gearbox of a VAZ-21099 vehicle directly affects the technical condition of the vehicle, the quality and service life of parts, safety and driving comfort. promotes smooth operation of the mechanism, reduces the friction force of parts against each other and acts as a heat exchanger, preventing the gearbox from failing due to overheating.
The gearbox oil should be changed regularly.
Theoretical information
Before the replacement process, any car owner is interested in the question - how many liters of oil are in the box of the VAZ-21099 car. From the technical factory documentation, it follows that in a 5-speed gearbox there is 3.3 liters, and in a 4-speed gearbox there are exactly 3 liters.
Oil change intervals
Based on the factory documentation, you need to change the oil every 70 - 80 thousand kilometers, but at least once every 4 - 5 years with an average annual mileage of 15 - 16 thousand km. In reality, the situation is somewhat different - weather conditions, environmental conditions, operating and storage (parking) conditions have a serious impact on replacement intervals. According to experts, every 35 - 40 thousand km., While in the interval after 30 thousand km. the emergence of primary signs of violations is already possible:
- heavy and inaccurate gear shifting;
- extraneous noise;
- vibration.
If the above signs began to appear in your car recently, we strongly advise you to change the oil as soon as possible - this will reduce the wear of gearbox parts and compensate for possible losses from breakdowns.
Which oil to choose
- Volnez TM4 ”(80W-90; GL-4);
- Omskoil trans P (80W-85; GL-4/5);
- Rexol T (80W-85; GL-4).
Among experienced motorists, the choice fell on the more reliable, in their opinion, manufacturers:
- Mobil;
- Castrol;
With the initial replacement at the VAZ-21099 checkpoint and the lack of experience in use, it is worthwhile to focus on the opinion of friends, reviews of motorists on the Internet and advice from reputable publications, which, as a result, will make it possible to make the correct and informed choice. We advise you to add oil to the gearbox manufactured by Zic or Castrol.
Level control and required volume
During the operation of the car, it is necessary to constantly check the checkpoint using a probe. There are two control marks (dashes) on the dipstick indicating the minimum and maximum oil level in the gearbox. The minimum mark indicates the need to refill (usually the operation is performed every 4 - 5 thousand km.), And the maximum - about the absence of reasons for excitement.
The control is carried out as follows:
- In the checkpoint, unscrew or remove the dipstick (the hole from it is usually used as a filler neck).
- Wipe the metal part with a dry, clean cloth.
- Insert the dipstick back and remove it again - you see the real oil level in the gearbox.
The standard is the amount of lubricant between the minimum and maximum, i.e. approximately in the middle of the marks.
Topping up oil
Topping up the oil in the "21099" checkpoint is carried out only after checking the level and taking into account its tendency to a minimum. As a rule, from 0.5 to 0.8 liters are added to a 5-mortar, and up to 0.6 liters in a 4-mortar. It is important to use oil of the same manufacturer and the same viscosity for refilling that is currently used in the gearbox of your car, mixing is unacceptable and can lead to complete failure of the gearbox or its individual parts. using an oil syringe or funnel, and then measure the level with a dipstick. Usually, topping up is carried out in stages, periodically controlling the level, since the volume in excess of the maximum will lead to squeezing out of the checkpoint through gaskets, oil seals and drives, which will definitely lead to their replacement.
What is needed to replace
For your own replacement, you must prepare the following set of tools and improvised means:
- overpass, lift or pit;
- spanner key for 12 and 17;
- filler syringe or funnel;
- soft wire, flexible hose 25 - 30 cm long, electrical tape;
- a canister or other empty container with a volume of 4 - 5 liters;
- replacement oil with a volume of 5 liters;
- dry clean cloth.
Warm up the vehicle and take a short trip of 5 to 6 kilometers before starting the replacement.
Step-by-step instruction
Having prepared the car and all the necessary tools for changing the oil in the gearbox with our own hands, we proceed to draining the old lubricant and cleaning the accompanying elements.
Drain the oil
Drive the car onto an overpass or inspection pit, prepare an empty container, keys and wire.
- Remove the rubber cap from the breather and clean it with a wire and cloth.
- Using a wrench, unscrew the drain plug on the gearbox and substitute an empty container to drain the old oil. The complete cleaning process will take 15 - 20 minutes.
- Screw the drain plug tightly into place.
The gearbox is fully prepared for changing the lubricant, which means you can proceed to the next stage.
Fill in new oil
If the checkpoint is equipped with a filler neck, then the filling process is quite simple:
- Insert a funnel into the filler neck.
- Fill in 3 - 3.3 liters of oil, depending on the number of gears in the box.
- Check the level with the dipstick.
If there is no filler neck, use an oil syringe, after putting a flexible hose on it and fixing the connection with electrical tape.
- Collect a full syringe (the final volume is tracked by the level on the canister).
- Insert the hose into the filler hole and use a syringe to pour in the required amount of lubricant.
- We tighten the filler plug tightly.
The process of changing the oil in the gearbox is complicated only at first glance and can be delayed during the first change, later you will be able to perform this operation in a matter of minutes and even with your eyes closed. Most importantly, do not forget, but rather write down the mileage at which the last change was.
The gearbox oil is changed every 75,000 km or after 5 years of operation. There may also be unscheduled replacements caused by oil leakage from the box due to leakage of oil seals. In general, when driving a VAZ 2108 2109 21099, it should be borne in mind that there is no metal protection for the engine crankcase and the gearbox housing in this car. Therefore, if you hover over a stone, curb, stump, in general, any obstacle that rises 20 centimeters above the road surface and hit it with a gearbox, then its replacement is guaranteed to you.
The fact is that the case of the gearbox is cast iron, and it cracks with a mechanical shock. And through the cracks formed, oil escapes. A broken gearbox is NOT REPAIR, it will only go for parts. Therefore, be more careful when driving in the forest and in a field with tall grass.
On cars VAZ 2108 2109 21099, serviced and non-serviced gearboxes are used. The serviced gearbox is equipped with a dipstick to control the oil level in it. The unmaintained one has only a drain and a filler hole. Accordingly, it is very problematic to control the oil level in it. Usually, oil is poured to the very top, and for control they run over a brick with the right front wheel. When the right wheel is on a brick, the oil level in the box on the side of the filler plug becomes slightly higher. You unscrew the plug a little - if the oil starts to flow, then its level is in order.
There is another way to control the oil level in an unattended gearbox VAZ 2108 2109 21099, but more on that later. So, you have a need for a box. And again, as in the case with engine oil, we are faced with the question: what kind of oil should we fill?
According to the vehicle operating instructions, it is necessary to fill in transmission oils 80w-95, however, the same instructions stipulate that it is allowed to fill the box with engine oil. When pouring engine oil into the VAZ 2108 2109 21099 gearbox, there are two advantages:
1) Engine oil is cheaper than transmission oil
2) Engine oil is less viscous in winter in frost (it is easier to change gears on an unheated car).
Therefore, again, given that, for the most part, the VAZ 2109 is a budget car, filling with engine oil is preferable.
So, first you need to drain the old gearbox oil. If you change the oil in the summer, then everything is fine. If in winter, then it is better to drive a couple of kilometers by car before replacing - so that the oil is more liquid. It is necessary to prepare a container where you will drain the old oil.
If you have an elevator or a pit in your garage, the process of draining the oil will be easy. If it is necessary to lie on the ground under the machine, then it is necessary to find a low bucket or basin in order to substitute it under the gearbox drain hole.
We take the 17 key and climb under the car, first unscrew the filler hole (to provide air access), then we substitute the container under the drain hole and unscrew the drain plug. About three liters of oil should pour out, if less, then you drove with a poorly lubricated gearbox. When the oil has completely stopped draining, or it flows in a thin stream for a long time, we twist the drain plug into place.
Now it is necessary to fill in new oil into the gearbox of your VAZ 2109. The manufacturer recommends doing this through the filler hole. Of course, in a VAZ 2109 with a serviced gearbox, this is easy to do: I took out a dipstick, inserted a funnel into this hole, and poured oil. However, in gearboxes without a dipstick (not serviced) it is very difficult to do this: the funnel cannot be inserted into this hole. If you build something like a hose with a cut-off bottle screwed to it, then the pouring process will be very long (although this is also a good option).
Therefore, the recommendation is as follows: pour oil through the hole of the speedometer drive with a pear. A pear is an ordinary large enema, the larger the better.
We unscrew the nut that secures the speedometer drive and take it out.
We leave the drive hanging on the side (the main thing is not to smear it, but we ourselves suck in new oil from the container into the pear, then we bring the pear to the hole of the speedometer drive and squeeze it into the box. We do this until the oil flows out of the filler hole left open on the side of the box Leaked - twist the side filler hole.
Through the hole in the speedometer drive, you can clearly see the oil level in the box now. This can be used for periodic control of the oil level in the box - removed the speedometer drive, looked at the level, put the speedometer drive in place. And there is absolutely no need to climb under the car. We put the speedometer drive in place, clamp it with a nut.
That's it, you have new oil in your gearbox.
The article will be useful not only to the owners of the VAZ 2109, in addition to this model, it is applicable to both 21099 and 2108, since the gearboxes in these models are absolutely identical. In general, changing the oil in the manual transmission VAZ 2109 (21099) is a fairly simple process and can be done with your own hands. But first things first.
Possible reasons for which an oil change is necessary
It is worth noting that the model 2109 (21099) and the like have gearboxes, so to speak, "indestructible". But even such a reliable unit has periods when, for further uninterrupted operation, it is necessary to carry out maintenance in the form of replacing the transmission fluid. If rustling or other noises began to be heard from the box, the unit produces strong vibrations, gears shift worse and are accompanied by unpleasant sounds - the time has come for an oil change. To begin with, check the oil level with a dipstick (if the replacement was made recently), and inspect the unit itself for leaks. Only then proceed directly to the replacement itself.
What is the oil change interval in the box VAZ 2109 (21099)
According to the regulations, the oil change is carried out every five years, or every 70 thousand kilometers. But in general, you should not stretch this interval so much, because the wear of VAZ boxes is usually quite large, and the operating conditions are usually close to extreme, in view of this, this period must be reduced to once in 40 thousand kilometers.
What kind of oil to fill
The most interesting thing is that in the manual transmission of VAZ 2109, 2108 and 21099, according to the regulations, it is allowed to fill in engine oil, but with the proviso that the replacement will be carried out as in the engine - every 10-15 thousand kilometers. But such measures were resorted to before, when transmission oils were practically not found. Now the assortment of these fluids is so large that many, even avid motorists with great driving experience, get lost and choose a suitable transmission fluid for a long time. In order not to get confused and exactly acquire what you need, follow the following instructions:
- The basic rule is that expensive does not mean high quality (when choosing, do not rely on the price, usually, the more expensive the oil, the higher the likelihood of a fake)
- First of all, pay attention to the marking, the viscosity should be 80W-85 or 80W-90
- The oil class must be GL-4 or GL-5, which corresponds to the domestic marking TM-3 and TM-4.
- For cars of the VAZ family, there are special transmission fluids developed for them, for example - "Rexol T", "Omskoil Trans P" and "Volonez TM4". When you come across these brands, buy something from them without hesitation.
- Purchase any oils only in specialized stores and from authorized dealers! This is very important to avoid counterfeiting.
What you need to have on hand
- Four liters of transmission fluid (the remainder will be refilled during operation). The exact amount of oil poured into the gearbox is three liters for a four-speed gearbox and three and a half liters for a five-speed gearbox (Answer to the question of how much oil to fill).
- Suitable place (observation pit, overpass, which is better - your choice)
- Funnel, preferably large in diameter and with a long end (for convenience).
- The key or the head on "17", you can do both.
- Old rags, wipe your hands with a probe, perhaps for something else.
- A large bowl for draining the waste liquid and a bottle for overflowing and then disposing of it (a five-liter canister is suitable).
- In addition, if you have a checkpoint without a dipstick, you will need a special syringe, a flexible hose 20-25 centimeters long.
- Thin wire and electrical tape.
This is the most basic thing that will certainly be needed in the process of the work performed.
Direct replacement (manual transmission in which the probe is provided)
During operation, we check the fluid level every 10-15 thousand kilometers in order to avoid transmission breakdowns due to low oil levels. If the box consumes a lot of oil, the replacement should be done as often as possible.
Oil change process (manual transmission in which the dipstick is not provided)
Conclusion
As you can see, changing the transmission fluid is quite easy and you should not go to a car service for this. All this can be done by yourself, thereby saving money and waiting time. And do not forget to check the transmission fluid level at the end of all work.
You should not wait for the onset of problems with the gearbox, having scored on the oil change schedule in the gearbox. It is better to change the oil as recommended by the manufacturer, namely every 70-80 mileage, or every three years. If the oil is old in age and production, it simply loses its properties and the gearbox on your machine is subject to increased wear under the same load conditions. So, we will tell you how to change yourself oil in the gearbox VAZ 2108, 2109, 21099. Ideally, do this on a lift, pit or overpass. We need a container to drain the mining. 3 liters of oil are poured into the 4-speed gearbox, and 3.3 liters of oil into the 5-speed gearbox. It is recommended to use 80W-85 GL-4432 oils from trusted manufacturers. so, the process itself.
We make our way to the drain plug on the gearbox. It is located at the bottom of the box.
Remove the rubber cap on the gearbox. We clean it. Next, we clean the breather in the gearbox and put the cap back on.
We proceed to drain the oil from the gearbox. Unscrew the drain plug on the VAZ 2108 gearbox and wait until the old oil drains. It is better to drain the oil on the "hot" checkpoint immediately after the trip. Warm oil will drain faster.
After the old oil has completely drained out, tighten the drain plug. We take out the oil level dipstick from the gearbox. In its place we insert a funnel and fill in with new oil.
When filling with oil, check its level with a dipstick. The level should stop midway between the minimum and maximum marks.
This procedure is described for boxes with a stylus. But there are also older gearboxes that do not have a dipstick. On old boxes, the drain plug and the filler plug are very close.
You can pour oil into it only with a special syringe.
This is how the procedure looks like oil changes in the gearbox VAZ 2108, 2109, 21099 We will be glad to see you in our club VAZ 2108, 2109, 21099
