1. Locate the oil filter. It is usually located near the bottom of the engine, on the driver's side. It is a cylindrical-shaped object with a black cap.
2. Place the oil filter wrench around the oil filter. Make sure that the wrench is snugly in place and will not slip.
3. Turn the oil filter wrench counterclockwise. This will loosen the oil filter and allow you to remove it.
4. Be careful not to spill any oil. As you remove the oil filter, some oil may leak out. Be prepared to catch the oil in a drip pan.
5. Inspect the old oil filter. Look for any damage, such as holes or tears. If the oil filter is damaged, replace it with a new one.
6. Apply a thin coat of new oil to the gasket of the new oil filter. This will help to create a seal and prevent leaks.
7. Screw on the new oil filter. Turn the oil filter clockwise until it is snug. Do not over-tighten the oil filter.
8. Fill the engine with new oil. Check the owner's manual for the correct amount of oil.
9. Start the engine and let it run for a few minutes. This will circulate the new oil throughout the engine.
10. Check the oil level. Make sure that the oil level is between the "full" and "add" marks on the dipstick.
That's it! You have now successfully replaced the oil filter on your 1997 E320 Mercedes-Benz.
