13. Cooling Fan Thermo Switch
The thermo switch mounted on the radiator
controls the operation of the cooling fan
motor.
In case that the fan motor fails to work,
disconnect the green and black/blue leads
and connect jump wires to the terminals, then,
turn on the main switch, the fan motor should
operate.
If the fan motor still fails to run, measure
battery voltage between the green and
black/blue leads.
If there is no voltage, check for blown fuse,
loose connection or short-circuit.
If the fan motor runs, check the thermo switch
in the manner as described below:
Hang the thermo switch on the bowl filled with
coolant to check the switch’s opening and
closing temperatures, confirm the switch is
open circuited at room temperature, and
increase the coolant temperature gradually.
The switch should have continuity at
95±3
.
Caution
Keep the coolant at a constant temperature at
least for three minutes. Sudden increase the
coolant temperature will cause the
thermometer and the tester to indicate wrong
readings.
Never let the thermometer and the thermo
switch contact the wall of the bowl, which may
result in wrong readings.
The thermo switch shall be placed in the
coolant until the teeth are completely
submerged.
