THERMOSENSOR INSPECTION
Keep flammable materials away from the electric heat-
ing element. Wear protective clothing, insulated gloves
and eye protection.
Drain the coolant (page 6-51.
Disconnect the thermosensor connector and remove the
thermosensor.
Suspend the thermosensor in a pan of coolant (50
-
50
mixture) on an electric heating element and measure the
resistance through the sensor as the coolant heats up:
NOTE:
Soak the thermosensor in coolant up to its threads with
at least 40 m m (1.57 in) from the bottom of the sensor.
Keep temperature constant for 3 minutes before test-
ing. A sudden change of temperature will result in in-
correct readings. Do not let the thermometer or
thermosensor touch the pan.

Replace the sensor if
it
is out of specifications by more
than 10 % at any temperature listed.
Install the thermosensor.
Apply sealant to the thermosensor threads. Do not apply
sealant to the sensor head.
