1. Start the engine and allow it to warm up until the temperature of the coolant reaches 80° C (176° F)-90° C (194° F).
2. Remove the engine oil filler cap.

3. Remove the drain plug to drain oil.
4. Use oil filter wrench MB991396, or equivalent, when using the oil filter MD136790 to remove the engine oil filter.
5. Clean the filter bracket side mounting surface and ensure the old O-ring has been removed.
6. Apply a small amount of engine oil to the O-ring of the new oil filter.
7. Where the oil filter O-ring touches the oil pan flange, tighten the oil filter to 14 Nm (10 ft. lbs.).
