ELECTRIC COOLING FAN - COMPONENT TESTING
MOTOR
Disconnect electric cooling fan motor at junction. Using 2
jumper wires, ground one lead and apply battery voltage to other. Fan
should rotate. If fan does not rotate, replace motor.
RADIATOR FAN SWITCH
Using an ohmmeter, check switch continuity in hot water.
Switch should be open at less than 180�F (82�C) and continuity should
exist at more than 185�F (85�C). Replace radiator fan switch if it
does not test as specified.
ELECTRIC COOLING FAN RELAY
1) Remove relay from relay box in front of right suspension
tower. Using jumper wires, connect battery to indicated terminals.
2) On 3000GT, continuity should exist between terminals No. 1
and 3. With battery disconnected, continuity should exist between
terminals No. 2 and 4 and should not exist between terminals No. 1 and
3.
3) On all other models, continuity should exist between
terminals No. 3 and 4. With battery disconnected, continuity should
exist between terminals No. 1 and 2 and should not exist between
