OIL AND FILTER

INSPECTION

1.

CHECK OIL QUALITY

Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If oil quality is visibly poor, replace the oil.

Oil grade:
API grade SJ, Energy–Conserving or ILSAC multi-
grade engine oil. SAE 5W–30 is the best choice for
your vehicle, for good fuel economy, and good start-
ing in cold weather.

2.

CHECK ENGINE OIL LEVEL

After warming up the engine and then 5 minutes after the en-
gine stop, oil level should be between the low level and full level
marks of the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.

3.

INSTALLATION

1.

INSTALL OIL PUMP

(a)

Place 2 new O–rings in position on the cylinder block.

(b)

Remove any old packing (FIPG) material and be careful
not to drop any oil on the contact surfaces of the oil pump
and cylinder block.

Using a razor blade gasket scraper, remove all the
old packing (FIPG) material from the gasket 
surfaces and sealing groove.

Thoroughly clean all components to remove all the
debris.

Using a non–residue solvent, clean both sealing
surfaces.

NOTICE:
Do not use a solvent which will affect the painted surfaces.

(c)

Apply seal packing to the oil pump as shown in the illustra-
tion.
Seal packing: Part No.08826–00080 or equivalent

Install a nozzle that has been cut to a 2 – 3 mm (0.08
– 0.12 in.) opening.

HINT:
Avoid applying an excessive amount to the surface. Be particu-
larly careful near oil passages.

Parts must be assembled within 5 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.

Immediately remove nozzle from the tube and rein-
stall cap.

(d)

Install the oil pump with the 9 bolts.
Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)
