How to Change the Oil on a 1998 Mercedes Benz ML320


1. Lift the vehicle with the jack, until there is enough room to work comfortably underneath it.
2. Place the jack stands beneath the vehicle frame. The jack stands should be sitting level on the ground.
3. Place the oil drip pan under the vehicle, centered beneath the oil drain plug.
4. Remove the oil drain plug. It is located on the bottom of the engine on the oil pan.
5. Allow the old oil to drain, until the flow comes to a stop. This can take up to 30 minutes to complete.
6. Replace the drain plug. Be sure to tighten it, with the wrench, before proceeding.
7. Remove the tools, jack stands and oil drain pan, from under the vehicle.
8. Lower the Mercedes ML320, carefully, to the ground.
9. Raise the vehicle hood, and locate the oil filter casing, on the driver's side of the vehicle, near the front of the engine compartment.
10. Remove the cover from the oil filter casing.
11. Lift the old filter out with the wrench, and carefully remove it from the plastic 'stick' it is attached to. Also, remove the old O-ring from the filter end of the stick, if it did not come off with the filter.
12. Install the new O-ring and filter on the stick.
13. Lower the filter assembly back into the filter casing, and replace the cover.
14. Remove the oil fill cover, and use the funnel to fill the engine with the new oil.
15. Replace the oil fill cover, and run the vehicle for several minutes. Check the oil level with the oil dipstick, and adjust the oil level, as needed.
