Component Inspection
INSPECTION OF ELECTRIC COOLING FAN1. INSPECT TEMPERATURE SWITCH
Location: On the water inlet.
(a) Using an ohmmeter, check that there is no continuity when the coolant temperature is above 93°C (199°F).
(b) Check that there is continuity when the coolant temperature is below 83°C (181°F).
- If continuity is not as specified, replace the switch.
2. INSPECT ENGINE MAIN RELAY
Refer to Computers and Control Systems.
3. INSPECT COOLING FAN RELAY
Location: The relay is located in the engine compartment relay box.
A. Inspect Relay Continuity
(a) Using an ohmmeter, check that there is continuity between terminals 1 and 2.
(b) Check that there is continuity between terminals 3 and 4.
- It continuity is not as specified, replace the relay.
B. Inspect Relay Operation
(a) Apply battery voltage across terminals 1 and 2.
(b) Check that there is no continuity between terminals 3 and 4.
- If operation is not as described, replace the relay.
4. INSPECT FAN MOTOR
(a) Connect the battery and ammeter to the fan motor connector.
(b) Check to see that the motor rotates smoothly, and current is as follows:
Current:
Coupe (Canada) 8.8 - 10.8 A
Others 5.8 - 7.4 A
