Engine Oil and Filter Change Refer to Figures 7-1, 7-2, 7-3, 7-4 & 7-5


Drain used engine oil while the engine and oil are still warm. The oil will drain more freely and carry away more impurities. Change oil as follows:

  • 1.

    Prepare vehicle for maintenance as outlined in steps 1-6 on page 22.

  • 2.

    Clean the area around the oil filter to keep dirt and debris out of the engine.

  • 3.

    Place a suitable container below the engine to catch used oil as it drains. Remove filler cap. Turn oil drain valve 1/4 turn counterclockwise and pull out to drain oil.

  • 4.

    Remove oil filter located on left side of engine with a filter wrench. Let remaining oil drain out.

  • 5.

    Push oil drain valve in and turn clockwise until hand tight. Replace oil drain cap.

  • 6.

    Clean oil filter base where the oil filter seats against it.

  • 7.

    Place a new replacement filter in a shallow pan with the open end up. Pour new engine oil in through the threaded center hole until oil reaches the bottom of the threads. Allow one or two minutes for the oil to be absorbed by the filter material.

  • 8.

    Coat new filter O-ring with clean engine oil and install filter to engine filter base.

  • 9.

    Hand tighten oil filter until O-ring seats. Finish tightening by turning in the filter an additional 2/3 to 1 turn.

  • 10.

    Dispose of used motor oil and filter in a manner that is compatible with the environment. Do not throw used oil in the trash, pour it on the ground, or down a drain.

  • 11.

    Fill engine with recommended oil and quantity. Do not overfill. See "Engine Oil Type and Capacity" and "Engine Oil Level Check" on page 31.

  • 12.

    Replace filler cap, start engine and check engine and oil filter for leaks. Correct any leaks before placing engine into service.
