ON−VEHICLE INSPECTION

HINT: sThe cooling fan may rotate when the ignition switch is turned from ACC to ON. This is nornal.

1. CHECK COOLING FAN OPERATION WITH LOW TEMPERATURE (Below 83 C (181 F))

1.  Turn the ignition switch ON.

2.  Check that the cooling fan stops.

If not, check the cooling fan relay and ECT , and check for disconnected connector or wire breaks between the cooling fan relay and ECT .

3. Disconnect the ECT connector.

4. 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 ECT ..

e. Reconnect ECT connector.

2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 98 C (208 F))

1. Start the engine, and raise ECT to above 98 C (208 F).

2. Check that the cooling fan rotates.

If not, replace the ECT .

3. INSPECT COOLING FAN

1. Disconnect the cooling fan connector.

2. Connect battery and ammeter to the cooling fan connector.

3. Check that the cooling fan rotates smoothly, and check the reading on the ammeter.

   Standard amperage: 4.9 to 8.5 A at 20 C (68 F)

If not, replace the cooling fan.
