COOLING
SYSTEM
WATER TEMPERATURE
AND
TEMPERATURE GAUGE
The following circuit diagram shows
the
electrical wiring for the thermometer. The major components are:
temperature gauge
in
contact with cooling water; and temperature indicator (water temperature meter).

INSPECTION
Test
the
temperature gauge sensor
at
the
bench
to
see if its
ohmic value changes, as specified, with temperature. The test
is
to
be run as follows: Connect
the
temperature guage
to
the
ohmmeter
and place
it
in the water contained in a jar, which
is
placed on a stove; heat
the
water
to
raise its temperature slow-
Iy, reading
the
thermometer placed
in
the
jar and also the
ohmmeter. A temperature gauge whose ohmic value does
not
change
in
the
proportion indicated below must be replaced.
