Water Temperature Sensor Inspection
.Suspend the sensor in a conta
iner
of coolant so that the
temperature
sensing projection and th
readed
portion are
submerged.
Using
an ohmmeter, measure the internal resistance of
the sensor across the terminal and the body at the
temperatures shown in the
table.

*If the ohmmeter does not show the
specified
values,
replace the sensor.
Fan Switch Inspection
• Using an
ohmmeter,
check to see that only the
connect
ions
shown in the table have continuity (about
zero ohms)
.
*If the switch has an open or short,
repair
or replace it
with new one.

Fan Switch
.Suspend the switch in a container of coolant so that the
temperature-sensing projection and threaded portion
are submerged.
• Suspend an accurate thermometer in the coolant.
NOTE
o The switch and thermometer must not touch the
container sides or bottom.
• Place the container over a source of heat and gradually
raise the temperature of the coolant
while
stirring the
coolant
gently.
