INSTALLATION
CAUTION:
Do not overtighten. Doing so may cause an oil leak.
1) Clean the oil filter installation surface on cylinder block or oil cooler.
2) Obtain a new oil filter and apply a thin coat of engine oil to the seal rubber.
3) Install the oil filter turning it by hand, being careful not to damage the seal rubber.

Tighten the oil filter with 65 mm (2.56 in) in diameter further (approx. 2/3 - 3/4 rotations) after the seal rubber of the oil filter comes in contact
with cylinder block or oil cooler. When using a torque wrench, tighten to 12 Nm (1.2 kgf-m, 8.7 ft-lb).

Tighten the oil filter 68 mm (2.68 in) in diameter (approx. 1 rotation) after the seal rubber of the oil filter comes in contact with cylinder block or
oil cooler. When using a torque wrench, tighten to 14 Nm (1.4 kgf-m, 10.3 ft-lb).
INSPECTION
1) After installing the oil filter, run the engine and make sure that no oil is leaking around seal rubber.
