1.Water pump

Check the impeller and shaft for rotation. If
they do not rotate freely or have noise, replace
the water pump assembly.
2.Thermostat(standard)
Hang the thermostat in the pan of water as
shown in the illustration. The thermostat must
be below the surface of the water and its must
be away from the sides of the pan. Heat the
water uniformly in the pan and measure a
temperature at which the valve starts opening
and a temperature at which the valve lift
(distance)is 8 mm (0.3 in.). Replace the
thermostat if defective.

Hang the thermoswitch in the pan of oil with its
temperature sensing end below the surface of
oil and measure the resistance while heating
the oil as shown in the illustration. If the resis-
tance is incorrect, replace the thermoswitch.

Oil in the pan is hot. Any contact can
cause severe burns.
Hang the thermounit in the pan of antifreeze
with its temperature sensing end below the
surface of antifreeze and measure the resist-
ance while heating the antifreeze as shown in
the illustration. If the resistance is incorrect,
replace the thermounit.
