COOLING FAN SYSTEM (1AZ±FSE)
ON±VEHICLE INSPECTION
HINT:
It is normal that the cooling fan sometime rotates when the ignition switch is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION WITH LOW TEMPERATURE (Below 83C (181F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and engine coolant temperature sensor, and check for disconnection of
connectors or wire break between the cooling fan relay and engine coolant temperature sensor.
(c) Disconnect the engine coolant temperature sensor connector.
(d) 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 engine coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 100C (212F))
(a) Start the engine, and raise coolant temperature to above 100C (212F).
HINT:
Coolant temperature is the detected value by the engine coolant temperature sensor on the water outlet.
(b) Check that the cooling fan rotates.
If not, replace the engine coolant temperature sensor.
3. INSPECT COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connector.
(c) Check that the cooling fan rotates smoothly, and check the reading on the ammeter.
Standard amperage:
5.2 to 8.2 A at 20C (68F) (M/T)
8.3 to 11.3 A at 20C (68F) (A/T)
(d) Reconnect the cooling fan connector.
4. INSPECT COOLING FAN No.2 (With Air Conditioner)
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the cooling fan connector.
(c) Check that the cooling fan rotates smoothly, and check the reading on the ammeter.
Standard amperage:
5.2 to 8.2 A at 20C (68F) (M/T)
8.3 to 11.3 A at 20C (68F) (A/T)
(d) Reconnect the cooling fan connector.
