1. Clean the areas around the drain plug, oil filter, oil
fill cap and dipstick.
2. Remove one of the oil drain plugs. A drain plug is
located on either side of the crankcase; one is
adjacent to and below the oil filter, the other is
below the starter.
3. Allow all oil to drain and then reinstall the drain
plug. Torque to 13.6 N·m (10 ft. lb.).
4. Remove the old filter and wipe off the filter adapter
with a clean cloth.
5. Place a new replacement filter in a shallow pan
with the open end up. Pour new oil, of the proper
type, in through the threaded center hole. Stop
pouring when the oil reaches the bottom of the
threads. Allow a minute or two for the oil to be
absorbed by the filter material.
6. Apply a thin film of clean oil to the rubber gasket
on the new filter.
7. Install the new oil filter to the filter adapter. Hand
tighten the filter clockwise until the rubber gasket
contacts the adapter, then tighten the filter an
additional 2/3-1 turn.
8. Remove the oil fill cap and fill the engine with the
proper oil to the ‘‘F’’ mark on the dipstick. Always
check the oil level with the dipstick before adding
more oil.
9. Reinstall the oil fill cap and dipstick.
10. Start the engine and check for oil leaks. Stop the
engine, correct any leaks, and allow a minute for
the oil to drain down, then recheck the level on the
dipstick.
