2. Although some sources recommend changing the oil filter every other oil change, the low cost of the oil filter and the relative ease of installation suggest that a new filter should be installed at each oil change.
3. Gather together all the necessary tools and materials before starting work (see illustration).
12.3. These tools are required when changing the engine oil and filter:
1 - Drain pan - it should be shallow but wide to prevent oil from splashing
2 - Rubber gloves - when removing the drain plug and filter, you will stain your hands with oil (gloves will also prevent burns)
3 - Extension - sometimes the oil sump drain plug is tightened very tightly, and an extension will be required to unscrew it to increase the shoulder
4 - Socket - used in conjunction with an extension
5 - Special wrench for removing the oil filter is a wrench with a metal strip
6 - Oil filter wrench - this type of wrench fits on the bottom of the filter and can be turned with a ratchet or ratchet (Wrenches of various sizes are available for different types of filters)
4. In addition, you should have a rag so that you can wipe up spilled oil. Access to the underside of the vehicle is noticeably improved if the vehicle can be raised on a lift.
Attention! Do not work under a vehicle that is only supported by a jack.
5. If this is your first oil change under the vehicle, be familiar with the location of the oil drain plug and oil filter. The engine and exhaust system parts will be hot during operation, so pay attention to their location so as not to touch them when working under the vehicle.
6. Warm up the engine to normal operating temperature. If new oil or any tools are needed, use the warm-up time to collect everything you need for the job. The required type of oil can be found in the subsection "Recommended oils and fluids" at the beginning of this chapter.
7. When the engine oil is warm (after warming up the engine oil, it flows out better, and more contaminants and bottom deposits are removed along with the oil), raise and support the vehicle. Make sure it is securely fastened.
8. Place all necessary tools, rags and newspapers under the car. Position the drain pan under the drain plug. Remember that at first the oil will flow out under pressure.
9. Be careful not to touch hot parts of the exhaust system. Loosen the drain plug at the bottom of the oil pan (see illustration). If the oil is too hot, gloves can be worn when removing the plug.
12.9. The engine oil drain plug is located at the rear of the oil pan. It is usually very tight, so use a spanner wrench to avoid stripping the edges of the hex
10. Let the old oil drain into the sump. As the oil flow decreases and breaks into separate drops, it may be necessary to move the sump further under the engine.
11. After the oil has drained, wipe the drain plug with a clean rag. Small metal particles can stick to the plug and contaminate the new oil.
12. Clean the area around the drain plug hole and reinstall it. Tighten the plug securely with a wrench. If you have a torque wrench, use it to tighten.
13. Move the oil pan into place under the oil filter.
14. To loosen the oil filter, use a special oil filter wrench (see illustration). A chain or a metal strip from a key can damage the oil filter shell, but this does not matter, since in any case the filter will be unusable.
12.14. The oil filter is usually also very tightly tightened, and a special wrench is required to unscrew it (do not use this wrench to tighten a new filter!)
15. Completely unscrew the old filter. Be careful - it's full of oil. Drain the oil from the filter into the drain pan.
16. Compare the old filter with the new one to make sure they are the same type.
17. Use a clean rag to remove all oil, dirt, and sediment from the area where the oil filter was attached to the engine. Look at the old filter and make sure the rubber gasket is not stuck to the engine. If this happens, remove the gasket.
18. Apply some oil to the rubber gasket of the new oil filter (see illustration), and also pour a small amount of fresh oil into it. Oil pressure will not build up in the engine until the pump has filled the filter with oil, so partial filling will reduce the amount of time the engine will run without oil.
12.18. Lubricate the oil filter gasket with clean engine oil before installing the filter on the engine
19. Install a new filter to the engine using the filter tightening recommendations stamped on the filter housing or on the filter box. Most filter manufacturers do not recommend using an oil filter wrench when tightening as this can overtighten the connection and damage the gasket.
20. Remove all fixtures, rags, etc. from under the car. Be careful not to spill oil from the drain pan. Lower the car.
21. Move to the engine compartment and locate the oil filler cap.
22. Pour clean oil through the filler hole. You can use a funnel.
23. Fill the engine with three quarts of clean oil. Wait a few minutes and let the oil drain into the sump, then check the level on the dipstick (see if necessary section 4). If the oil level is above the mark "ADD", start the engine to allow the new oil to fill all the lubrication channels.
24. Start the engine and let it run for about 1 minute, then shut it off. Check under the vehicle for leaks at the oil sump drain and around the oil filter. If at least one of these places is leaking, tighten the connections with more force.
25. When new oil circulates through the lubrication circuit and the filter is full, recheck the oil level on the dipstick and top up if necessary.
26. During the first trips after an oil change, make it a habit to check for leaks and the oil level frequently.
27. Old oil drained from the engine must not be reused. Oil refining stations, car workshops and gas stations usually accept oil that can be cleaned and reused.
