Fan Motor Test
1. Disconnect the 2-P connector from the fan motor.
2. Test the motot by connecting battery power to the
B terminal, and ground to the A terminal
3. lf the Jan motor fails to run smoothly, replace it.
NOTE: The illustration shows the radiator fan.
Engine Coolant Temperature (ECT)
Switch Test
NOTE: Bleed air from the cooling system atter install-
ing the engine coolant temperature (ECT) switch (see sec-
tion 1O).
1. Remove the ECT switch from the thermostat
housing.
2. Suspend the ECT switch in a container of coolant
as shown.
Heat the coolant and check engine coolanl tempera-
ture with a thermometer.
