ENGINE OIL
INSPECTION
1. Be sure the vehicle is on level ground.
2. Warm up the engine to normal operating temperature and
stop it.
3. Wait for five minutes.
4. Remove the oil level gauge and check the oil level and con-
dition.
5. Add or replace oil as necessary.
Note
l The distance between the L and F marks on the level
gauge represents 0.8 liter (0.85 US qt, 0.70 Imp qt).
REPLACEMENT
Warning
l Be careful when draining; the oil is hot.
1. Warm up the engine to normal operating temperature and
stop it.
2. Remove the oil filler cap and the oil pan drain plug.
3. Drain the oil into a suitable container.
4. Install a new gasket and the drain plug.
Tightening torque:
29-41 N,m (3.0-4.2 m-kg, 22-30 ft-lb)
5. Refill the engine with the specified type and amount of en-
gine oil.
6. Refit the oil filler cap.
7. Run the engine and check for leaks.
8. Check the oil level and add oil if necessary.

1. Remove all foreign material from the contact surfaces.
2. Apply silicone sealant to the contact surfaces of a new oil
pan gasket, shown in the figure.
3. Install new gaskets onto the oil pump body and the rear
cover with the projections in the notches shown in the figure.
4. Apply a continuous bead of silicone sealant to the oil pan
along the inside of the bolt holes and overlap the ends.
5. Install the oil pan.
