How to Change the Oil Filter on a Mercedes 500 SEL

1. Raise the hood and locate the oil filter housing. Remove the retaining bolt from the top of the housing with a 13mm socket wrench. Pull the cap up and off the housing. Remove the oil filter from the housing; it will still contain oil so have a container close-by to place it into.
2. Install the larger rubber O-Ring supplied with the new filter under the oil filter housing cap. Then install the small aluminum washer under the oil filter housing bolt.
3. Insert the new oil filter into the filter housing. Replace the oil filter housing cap and tighten the bolt.
