5-6 COOLING SYSTEM
REMOVAL
Remove the fuel tank. ( 4-2)
Drain the engine coolant. ( 2-15)
Do not open the radiator cap when the engine is hot,
as you may be injured by escaping hot liquid or va-
por.
The engine must be cool before servicing the cool-
ing system.
Engine coolant may be harmful if swallowed or if it
comes in contact with the skin or eyes. If engine cool-
ant gets into the eyes or contacts the skin, flush the
eyes or wash the skin thoroughly, with plenty of wa-
ter. If engine coolant is swallowed, induce vomiting
and call a physician immediately.
COOLING FAN
Remove the fuel tank. ( 4-2)
Disconnect the cooling fan motor coupler.
Test the cooling fan motor for load current using an ammeter
connected as shown.
The voltmeter is for making sure that the battery applies 12 volts
to the motor. With the motor with electric motor fan running at full
speed, the ammeter should be indicating not more than 5 am-
peres.
If the fan motor does not turn, replace the motor assembly with a
new one.
Disconnect the cooling fan motor coupler 1, cooling fan
thermoswitch coupler 2, and engine coolant temperature
thermoswitch lead wires 3.
