As you know, car maintenance should be carried out according to the instructions. Late maintenance often leads to disastrous results.
On the VAZ 2109, many motorists know how to change the oil in a box, but they make mistakes. One thing you need to know for sure - its replacement is carried out every 35 thousand mileage.
On a vaz 2109, how to change the oil qualitatively is akin to art, the step-by-step instructions for the process of which are given below.
The process of changing the oil in a box vaz 2109
To carry out these works, you will need tools and the following accessories:
- wrench or head to unscrew the drain plug;
- jack for lifting the front of the machine;
- five-liter capacity;
- plastic funnel with a narrow stack;
- rags;
- latex gloves.
Note. The manufacturer recommends synthetic multigrade gear oil 80 W-85. GL-4432.
For a four-speed gearbox, three liters are enough. If the box is five-speed, then three and a half liters are used.
Start of work
So:
- Drive the heated car into the garage, where there is an inspection hole.
- Place wheel chocks under the rear of the machine.
- Put the car on the handbrake (see).
- Remove the negative terminal from the battery.
- Raise the right front side, in the direction of travel, with a jack.
- Substitute a reliable support device in case of failure of the jack or other unforeseen cases.
- Go down into the viewing hole.
- Remove the rubber plug from the breather on the box.
- Clean it of accumulated dirt, rinse.
- Clean the breather inside, use a soft wire for this.
- Put the stopper in place.
Note: to carry out work, it is necessary to cut off the upper tapering part of a five-liter plastic canister and you will get a good container for draining liquids.
Oil drain
So:
- Carefully unscrew the drain bolt with a spanner wrench. The prepared container should be nearby.
Attention! It is necessary to remove the cork carefully and at the same time try to be a little to the side, in such a position as to prevent hot liquid from getting on yourself.
- Substitute the canister in advance, remove the cork.
- Wait until all content has drained.
- Put the plug in place, screw it in until it stops. Wash the drain area.
- Remove the container, it can be useful for lubricating old parts.
Note: it is advisable to carry out work wearing rubber gloves, as the oil is absorbed by the skin of the hands and does not wash off for a long time.
fill
Necessary:
- Pull out the oil level dipstick.
- Insert a plastic funnel, pour fresh. It is necessary to fill in the amount that is required for the car.
- Wait 20-30 minutes for it to flow from the walls of the filler neck.
- Use a dipstick to check the level, the oil should remain in the middle between the marks.
- Wipe the dipstick, put in place.
If an old box is installed on the car, a probe is not provided there. The drain plug is located next to the filler neck.
Then you need to carry out the oil pump. It is a closed container with a pressurizing pump. Rubber hose with tip and tap for opening.
Necessary:
- Unscrew the filling plug, put it next to it.
- Pour the required amount into the tank, create pressure with a pump.
- Insert into the hole in the filling part, open the tap.
- Before removing the tip, prepare the cork.
- Remove the tip at the same time, immediately insert the stopper. Spin it.
- Wipe the box clean of spilled liquid.
Note: work must be carried out carefully, carefully.
Replacement must be made due to the development of additives in it, which are added by manufacturers. They are used to remove heat during the operation of the box parts.
When driving in the city, there is a frequent gear change and a sharp increase in speed. For this reason, the temperature in the working part reaches 300 0 C.
With such a temperature load, foaming of the oil begins, it loses its ability to lubricate working parts. Therefore, manufacturers add additive ingredients.
When driving at high speeds, it is recommended to change the oil after every 25-30 thousand mileage.
The technology for the production of synthetic gear oil with additives allows operation in the critical temperature conditions of the outside air. It does not lose its viscosity either during frost or in hot heat, therefore it is called all-weather.
Some motorists are wondering: “Do I need to flush the box after draining the oil?”:
Recommendation.
It merges with a heated box. Its temperature reaches the limits of 50 0 C, it has a liquid content.
Draining occurs under the inclination of the vehicle towards the drain neck. All formed small particles of metal settle at the bottom.
The cork is at the lowest point. Therefore, the oil drains along with the sediment, leaving no impurities.
- Therefore, flushing can be omitted.
You can change the oil in the VAZ-2109 gearbox with your own hands after watching the video, which provides a detailed description, a story about the procedure for carrying out the work. From the photo you can study the location of the probe, drain neck.
See all the unexpected nuances of car maintenance. It is also necessary to read the instructions for using oils, the content of additives in its composition.
The price of a three-liter canister of synthetic gear oil from a good manufacturer is within 1,500 rubles. Self-changing the oil does not cause additional costs, subject to the rules of work, all procedures will be completed successfully.
