- Only high quality filters should be used to ensure proper engine operation. When replacing the filter, make sure that the rubber gasket from the old oil filter is completely removed from the mating surface of the cylinder block.
- Start the engine and warm it up to a temperature of 80-90°C.
- Remove the engine oil filler cap.
- Remove the plug and drain the engine oil from the engine. Be careful as the drained oil is very hot.
Unscrew the oil filter with a special wrench (pic. 2.73):
- wrench MD991396 for oil filter MD135737;
- wrench MD991610 for oil filter MD136466;
- universal wrench for oil filters except filters MD135737 and MD136466.

- Start the engine and let it run for a few minutes. Check it for oil leaks around the filter and the oil drain plug on the sump. Be aware that the oil pressure indicator light may stay on for several seconds as the oil must fill all channels and oil reservoirs in the engine.
- Dispose of the oil filter in accordance with current legislation.
