INSPECTION
1. INSPECT WATER PUMP
(a) Visually check the air hole for coolant leakage.
If leakage is found, replace the water pump.
If engine coolant has leaked onto the timing belt, replace the
timing belt.
(b) Turn the pulley, and check that the water pump bearing
moves smoothly and quietly.
If necessary, replace the water pump.
2. INSPECT TIMING BELT COMPONENTS

REMOVAL
HINT:
Removal of the thermostat would have an adverse effect, caus-
ing a lowering of cooling efficiency. Do not remove the thermo-
stat, even if the engine tends to overheat.
1. DRAIN ENGINE COOLANT
2. w/ Oil Cooler:
REMOVE OIL FILTER (See page LU±2)
3. REMOVE WATER INLET AND THERMOSTAT
(a) Remove the 2 nuts, and disconnect the water inlet from
the water pump cover.
(b) Remove the thermostat.
(c) Remove the gasket from the thermostat.

INSPECTION
INSPECT THERMOSTAT
HINT:
The thermostat is numbered with the valve opening tempera-
ture.
(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.
(c) Check the valve lift.
Valve lift: 8 mm (0.31 in.) or more at 95°C (203°F)
If the valve lift is not as specified, replace the thermostat.
(d) Check that the valve is fully closed when the thermostat
is at low temperatures (below 40°C (104°F)).
If not closed, replace the thermostat.
