1. It is advisable to change the oil immediately after a trip so that the engine and gearbox are warmed up to operating temperature.
2. Park the car on a level surface, apply the handbrake and turn off the ignition. To expand the working space, raise the front of the car and put it on stands. Keep in mind that the vehicle will need to be lowered in order to get an accurate reading when checking the oil level.
3. Wipe the check hole plug (this hole is also for filling oil), which is located in front of the gearbox housing. Unscrew the plug and wipe.
4. Substitute the pan under the drain plug, which is located on the left side in the gearbox differential housing.
5. Drain the oil into the pan, taking care not to burn yourself. Thoroughly clean the drain and control plugs, removing metal particles from the magnetic inserts.
6. After the oil drains, clean the threads on the plugs and in the crankcase, tighten the drain plug to the specified torque. If the car has been raised, lower it onto its wheels.
7. Refueling the gearbox is a rather laborious operation. Before checking the level, you must wait a long time so that the oil is completely glass. Keep in mind that while checking the oil level in the gearbox, the car must be on a flat, level surface.
8. Fill the gearbox with the correct grade and quantity of oil, then check the level (see subsection 2.2.8). If the standard amount of oil is poured into the gearbox, and a lot of oil flows out when checking the level, then wrap the check hole plug and make a short trip so that the oil is evenly distributed throughout the interior of the crankcase and gearbox parts. Returning to the original place, check the level again.
9. If the level is correct, tighten the plug to the specified torque.
