Suspend the switch in a pan of coolant (50-50
mixture) and check the temperatures at which the
switch opens and closes. Make sure that there is no
switch continuity with room temperature and
gradually raise the coolant temperature. The switch
should have continuity (close) at 98-102°C (208-
2150F).
NOTE
Keep temperature for 3 minutes before
testing continuity. A sudden change of
temperature will cause error of tempera·
ture reading between the thermometer and
the switch.
Do not let the thermometer or switch
touch the pan
a~
it will give a fales reading.
Soak the switch in coolant up to its
threads.
TEMPERATURE SENSOR
Disconnect the green/blue wire from the tempera·
ture sensor.
With the engine cold, use an ohmmeter to measure
resistance between the temperature sensor terminal
