Toyota Corolla Repair Manual: On–vehicle inspection
1. Check cooling fan operation with low temperature (below 83 c (181 f))
- Turn the ignition switch on.
- check that the cooling fan stops.
Hint
: if not, check the cooling fan relay and water temperature sensor, and check for separated connector or severed wire between the cooling fan relay and water temperature sensor.
- disconnect the water temperature sensor connector.
- check that the cooling fan rotates.
If not, check the fuses, cooling fan relay, ecm and cooling fan, and check for a short circuit between the cooling fan relay and water temperature sensor.
- reconnect the water temperature sensor connector.
2. Check cooling fan operation with high temperature (above 93 c (199 f))
- start the engine, and raise coolant temperature to above 93 c (199 f).
Hint
: coolant temperature is the detected value by the water temperature sensor on the water outlet.
- check that the cooling fan rotates.
Hint
: if not, replace the water temperature sensor.
3. Inspect cooling fan
- disconnect the cooling fan connector.
- connect battery and ammeter to the connector.
- check that the cooling fan rotates smoothly, and check the reading
