HINT: The thermostat is numbered with the valve opening
temperature.
(a) Immerse the thermostat in water and gradually heat the wa-
ter.
(b) Check the valve opening temperature.
Valve opening temperature:
80 ± 845C (176 ± 1835F)
If the valve opening temperature is not as specified, re-
place the thermostat.
(e) Check the valve lift.
Valve lift:
8 mm (0.31 in.) or more at 95°C (203°F)
If the valve lift is less than specification, replace the
thermostat.
INSTALLATION OF THERMOSTAT
1. PLACE THERMOSTAT IN WATER INLET HOUSING
(a) Install a new gasket to the thermostat.
(b) Align the jiggle valve of the thermostat with protrusion of the
water inlet housing and, insert the thermostat in the water
inlet housing.
2. INSTALL WATER INLET HOUSING AND THERMOSTAT

Valve lift:
8.5 mm (0.335 in.) or more at 95
°C (203°F)
If the valve lift is less than specification, replace the ther-
mostat.
(d) Check that the valve spring is tight when the thermostat
is fully closed.

(See page CO±15)
1. REMOVE TANK PLATE
(a) Raise the claws of the tank plates with SST in the
numerical order shown in the figure.
SST 09230±00010
NOTICE: Be careful not to damage the core plate.
2. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap
tester.
(b) Warm up the engine.
(c) Pump it to 1.2 kg/cm
2 (17.1 psi, 118 kPa), check that
pressure does not drop.
If the pressure drops, check for leaks as the hoses, radiator
or water pump. If no external leaks are found, check the heat-
er core, cylinder block and head.

INSTALLATION OF RADIATOR
1. INSTALL ELECTRIC COOLING FANS TO RADIATOR
2. INSTALL RADIATOR
Place the radiator in position, and install the two supports
with the two bolts.
HINT: After installation, check that the rubber cushion (A)
of the supports are not depressed.

10. START ENGINE AND CHECK FOR LEAKS
11. (A/T)
CHECK AUTOMATIC TRANSMISSION (A/T) FLUID
LEVEL
NOTICE: Do not overfill.
(d) Check for water leaks.
HINT: On radiators with resin tanks, there is a clearance
between the core plate and tank plate where a minute
amount of air will remain, giving the appearance of an
air leak when the radiator is submerged in water. There-
fore, before performing the water leak test, first switch
the radiator around in the water until all air bubbles dis-
appear.
7. PAINT TANK PLATE
HINT: If the water leak test checks out okay, allow the radia-
tor to completely dry and then paint the tank plate.
