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. DISCONNECT RADIATOR OUTLET HOSE
3. REMOVE WATER INLET AND THERMOSTAT
(a) Remove the 2 nuts holding the water inlet to the inlet
housing, and disconnect the water inlet from the inlet
housing.
(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°C)
If the valve lift is not as specified, replace the thermostat.
(d) Check that the valve spring is tight when the thermostat
is at low temperatures (below 40°C (104°F)).
If not closed, replace the thermostat.

INSTALLATION
1. PLACE THERMOSTAT IN WATER INLET HOUSING
(a) Install a new gasket onto the thermostat.
(b) Align the thermostat jiggle valve with the protrusion of the
water inlet housing, and insert the thermostat in the water
inlet housing.
HINT:
The jiggle valve may be set within 15° of either side of the pre-
scribed position.
2. INSTALL WATER INLET
Install the water inlet with the 2 nuts.
Torque:20 N·m (200 kgf·cm, 15 ft·lbf)
3. CONNECT RADIATOR OUTLET HOSE
4. FILL WITH ENGINE COOLANT
5. START ENGINE AND CHECK FOR LEAKS

RADIATOR
ON−VEHICLE CLEANING
Using water or a steam cleaner, remove any mud or dirt from the radiator core.
NOTICE:
If using a high pressure type cleaner, be careful not to deform the fins of the radiator core (i.e. Main-
tain a distance between the cleaner nozzle and radiator core).

ON−VEHICLE INSPECTION
1. REMOVE RADIATOR CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:
If the radiator cap has contaminations,always rinse it with
water.
Using a radiator cap tester, pump the tester and measure the
relief valve opening pressure.
Standard opening pressure:
74 − 103 kPa (0.75 − 1.05 kgf/cm
2, 10.7 − 14.9 psi)
HINT:
Use the tester’s maximum reading as the opening pressure.
If the opening pressure is less than standard, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
4. REINSTALL RADIATOR CAP
