THERMOSTAT REMOVAL
HINT: Removal of the thermostat would have an ad±
verse effect, causing a lowering of cooling efficiency.
Do not remove the thermostat, even if the engine
tends to overheat.
1. DRAIN ENGINE COOLANT (See page EG1±241)
2. REMOVE OIL FILTER
Using SST, remove the oil filter.

THERMOSTAT INSTALLATION
(See Components for Removal and Installation)
1. PLACE THERMOSTAT IN WATER PUMP
(a) Install a new gasket to the thermostat.
(b) Align the jiggle valve of the thermostat with the upper
side of the stud bolt, and insert the thermostat in the
water pump.
HINT: The jiggle valve may be set within 5
of either
side of the prescribed position.
2. INSTALL WATER INLET
Install the water inlet with the 2 nuts.
Torque: 8.8 N±m (90 kgf±cm, 78in.±Ibf)
(c) Check the valve lift.
Valve rift:
8 mm (0.31 in.) or more at 95
C (203
F)
If the valve lift is not as specified, replace the thermo±
stat.
(d) Check that the valve spring is tight when the thermo±
stat is fully closed.
If not closed, replace the thermostat. (a) Immerse the thermostat in water and gradually heat
the water.
(b) Check the valve opening temperature.
Valve opening temperature:
80 ± 84
C (176 ± 183
F)
If the valve opening temperature is not as specified,
replace the thermostat.
THERMOSTAT INSPECTION
INSPECT THERMOSTAT
HINT: The thermostat is numbered with the valve
opening temperature.

7. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to ªFº mark. (c) Tighten the oil filter by hand until the rubber gasket
contacts the seat of the filter mounting. Then using
SST, give it an additional 3/4 turn to seat the oil filter.
SST 09228±06500
4. FILL WITH ENGINE OIL
5. FILL WITH ENGINE COOLANT (SEE PAGE EG1±241)
6. START ENGINE AND CHECK FOR LEAKS 3. INSTALL OIL FILTER
(a) Clean the oil filter contact surface on the filter
mounting.
(b) Lubricate the filter rubber gasket with engine oil.
