Removal
1. Disconnect the radiator fan motor connector.
2. Set the heater temperature control to the "hot" position.
3. Unscrew the radiator drain plug to drain the coolant.
4. Disconnect the upper and lower hoses and the overflow tube.
5. For vehicles with automatic transmission, disconnect the oil cooler hoses from the transmission.
Warning. Cap the ends of the oil cooler hoses and the automatic transmission window to prevent leakage from the transmission and the entry of foreign objects into the transmission.
6. Remove the radiator mounting bolts.
7. Remove the radiator together with the fan motor.
8. Remove the fan motor from the radiator.
Examination
1. Check for bent, broken or clogged radiator fins.
2. Check the radiator for corrosion, damage, rust or scale.
3. Check the radiator hoses for wear, damage and cracks.
4. Check the reserve tank for damage.
5. Check the radiator cap spring for damage. Use the device to perform a pressure test on the plug.
6. Check for cracks or damage to the radiator cap seal.
Radiator Fan Motor
1. Make sure the fan rotates when battery voltage is applied to the terminals (as shown in the picture).
2. Check that there is no abnormal noise when the electric motor rotates.
