Every 16,000 km or 12 months.
1. Before you begin this procedure, make sure you have all the necessary tools. Prepare rags or old newspapers. They will come in handy for absorbing oil spills.
2. To prevent scalding and protect your skin from irritation from the oil, it is recommended to wear gloves.
3. To improve access to the underside of the vehicle, raise it and place it on supports (or use a ramp or lift).
Warning: Do not work under a vehicle that is supported solely by a jack (hydraulic or parallelogram) or that is supported on unreliable supports (pieces of wood, etc.).
4. Locate the drain plug located at the rear of the oil pan. The engine and exhaust system will be hot during this procedure, so try to complete it while the engine and accessories are still warm.
5. It is recommended to change the oil while the engine still maintains normal operating temperature, immediately after driving (when the temperature gauge needle is in the "Normal" sector). At the same time, the warmed oil and sediment flow out more easily.
6. Place the vehicle on a firm, level surface, fully apply the parking brake. Then engage first gear or reverse (manual transmission) or set the selector to position "P" (automatic transmission). Open the hood and remove the engine oil filler cap from the cylinder head. Then pull the oil level dipstick out of its socket (paragraph 3).
7. Raise the front of the vehicle and support it.
8. On 4-cylinder models, remove the right front wheel to gain access to the oil filter. You can also remove the accessory drive belt cover (secured with two latches) to gain more space.
9. On models with a 6-cylinder engine, you can remove the shield from under the radiator for easy access to the filter. But this is not necessary.
10. Be careful not to touch the hot parts, place a container under the drain plug and then unscrew it (see Fig. 3.10).
11. Allow the oil to flow into the container, while you check the condition of the plug gasket and replace it if necessary.
12. Wait for the used oil to drain into the container. As the oil stream weakens, move the container underneath it. After the oil has drained completely, wipe the plug and its threads in the pan, then screw the plug back in and tighten it to the required torque.
13. Now move the used oil container underneath the filter. On 4-cylinder engines, the filter is located on the rear right side of the cylinder block. On 6-cylinder engines, the filter is located on the front of the cylinder block.
14. Use a special tool to unscrew the filter. Be prepared for oil leakage (see Fig. 3.14). Inspect the old filter and make sure that the rubber sealing ring is not stuck to the engine. If it is stuck, carefully remove it. Quickly turn the filter with the opening facing up to spill as little oil as possible.
15. Using a clean, lint-free cloth, wipe the surface of the cylinder block in the filter installation area. If the filter installation method is not specified in the instructions supplied with it, install it as follows.
16. Apply a small amount of clean engine oil to the filter sealing ring (see Fig. 3.16).
17. Screw the filter into place until it stops. Then tighten it an additional 1/2-3/4 of a turn. Tighten the filter by hand only - do not use any tools.
18. Remove any remaining oil and all tools from under the vehicle, install the wheel and lower the vehicle to the ground.
19. Fill the engine with the required amount of oil of the regulated grade (see Fig. 3.19). First, drink half of the required amount, then wait a few minutes for the oil to drain into the pan. Continue pouring oil in small portions until the level reaches the lower mark on the dipstick. It takes about 0.5-1 liter of oil for the level to rise from the lower to the upper mark.
20. Start the engine. The oil pressure light will come on for a few seconds and go out when the new filter is filled with oil. Do not rev the engine while this light is on. Let the engine run for a few minutes and check for leaks around the filter seal and drain plug.
21. Turn off the engine and wait a few minutes for the oil to drain back into the pan. Now, after filling the engine channels and filter with new oil, check the level again with the dipstick and add oil if necessary.
22. Used oil must be disposed of in accordance with the "Basic Repair Procedures".
Note: It is immoral and illegal to dump used oil on the ground. Collect it in a special container and hand it over to the nearest motor pool for recycling.
