Thermostat
C: INSPECTION
Replace the thermostat if the valve does not close
completely at an ambient temperature or if the fol-
lowing test shows unsatisfactory results.
Immerse the thermostat and thermometer in water.
Raise water temperature gradually, and measure
the temperature and valve lift when the valve be-
gins to open and when the valve is fully opened.
During the test, agitate the water for even temper-
ature distribution. The measurement should be to
the specification.

B: INSTALLATION
1) Wipe and clean the oil filter matching surface on
cylinder block and oil cooler.
2) Get a new oil filter and apply a thin coat of engine
oil to the seal rubber.
CAUTION:
Be careful not to use the oil filter 80 mm (3.15 in)
in diameter to turbo model.
3) Install the oil filter by turning it by hand, being
careful not to damage seal rubber.
 Tighten the oil filter 80 mm (3.15 in) or 65 mm
(2.56 in) in diameter by approx. 2/3 — 3/4 rotation
more after the seal rubber of oil filter comes in con-
tact with cylinder block or oil cooler.
 Tighten the oil filter 68 mm (2.68 in) in diameter
by approx. 1 rotation more after the seal rubber of
oil filter comes in contact with cylinder block or oil
cooler.
CAUTION:
Do not tighten excessively, or oil may leak.
C: INSPECTION
1) After installing the oil filter, run the engine and
make sure that no oil is leaking around seal rubber.
NOTE:
The filter element and filter case are permanently
jointed; therefore, interior cleaning is not neces-
sary.
2) Check the engine oil level. 10, INSPECTION, Engine Oil.>
