3. Thermostat
A: REMOVAL AND INSTALLATION
1) Drain engine coolant.
Set container under the vehicle, and remove drain cock
from radiator.
2) Disconnect radiator outlet hose from thermostat cover.
3) Remove thermostat cover and gasket, and pull out the
thermostat.
G2M0227
4) Install the thermostat in the intake manifold, and install
the thermostat cover together with a gasket.
CAUTION:
When reinstalling the thermostat, use a new gasket.
The thermostat must be installed with the jiggle pin
upward.
In this time, set the jiggle pin of thermostat for front
side.
G2M0215
B: INSPECTION
Replace the thermostat if the valve does not close com-
pletely at an ambient temperature or if the following test
shows unsatisfactory results.
Immerse the thermostat and a thermometer in water. Raise
water temperature gradually, and measure the temperature
and valve lift when the valve begins to open and when the
valve is fully opened. During the test, agitate the water for
even temperature distribution. The measurement should
be to the specification.
Starts to open:
76.0—80.0°C (169—176°F)
Fully opens:
91°C (196°F)
