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. REMOVE AIR CLEANER CAP ASSEMBLY AND AIR
FILTER
3. DISCONNECT NO.2 ECT SWITCH CONNECTOR
4. DISCONNECT ENGINE WIRE PROTECTOR FROM
WATER INLET AND RH CYLINDER HEAD

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: 10.0 mm (0.394 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.

INSTALLATION
1. PLACE THERMOSTAT IN WATER PUMP
(a) Install a new gasket on to the thermostat.
(b) Align the thermostat jiggle valve with the upper stud bolt,
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 3 nuts.
Torque: 8 N´m (80 kgf´cm, 69 in.´lbf)
3. INSTALL WATER INLET PIPE
(a) Install a new O±ring to the water inlet pipe.
(b) Apply soapy water to the O±ring.
(c) Connect the water inlet pipe to the water inlet.
(d) Install the bolt holding the water inlet pipe to the cylinder
head.
Torque: 19.5 N´m (200 kgf´cm, 14 ft´lbf)

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 blow out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:

If the radiator cap has contaminations, always rinse
it with water.

When performing steps (a) and (b) below, keep the ra-
diator cap tester at an angle of over 30° above the hor-
izontal.

Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/(3 seconds or more)
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the tester and measure the relief valve opening
pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be re-
duced.
Standard opening pressure:
83 ± 113 kPa (0.85 ± 1.15 kgf/cm
2, 12.1 ± 16.4 psi)
Minimum opening pressure:
69 kPa (0.7 kgf/cm
2, 10.0 psi)
HINT:
Use the tester's maximum reading as the opening pressure.
If the opening pressure is less than minimum, 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 127 kPa (1.3 kgf/cm
2, 18.5 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 cylinder head.
