Repair Procedures

Inspection

Cap Testing
1. Remove the radiator cap, wet its seal with engine coolant, then install it to pressure tester.




2. Apply a pressure of 93 - 123kPa (0.95 - 1.25kgf/cm2, 14 - 19psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.

Radiator Leakage
1. Wait until engine is cool, then carefully remove the radiator cap and fill the radiator with engine coolant, then install a pressure tester on it.




2. Apply a pressure of 93 - 123kPa (0.95 - 1.25kgf/cm2, 14 - 19psi).
3. Inspect for engine coolant leaks and a drop in pressure.
4. If the pressure drops, check hoses, the radiator and the water pump for leakage. If there is no leakage, inspect the heater core, the cylinder block and the cylinder head.
5. Remove the tester and reinstall the radiator cap.

NOTE:
Check for engine oil in coolant and/or coolant in engine oil.

Removal

1. Disconnect the battery negative cable
2. Loosen the drain plug and drain the engine coolant.
3. Remove the air duct (A).
4. Remove the air cleaner assembly (C) after removing the AFS connector (B).

Tightening torque :
Bolt : 7.8 - 9.8N.m (0.8 - 1.0kgf.m, 5.8 - 7.2lb-ft)
Clamp : 2.9 - 4.9N.m (0.3 - 0.5kgf.m, 2.2 - 3.6lb-ft)




5. Remove the radiator upper hose (A).




6. Remove the radiator lower hose (A).




7. Remove the radiator.
(1) Remove the cooling fan connector (A).
(2) Remove the reservoir tank (B).
(3) Remove the fan assembly (C).
(4) Remove the radiator upper mounting bracket and radiator from the vehicle.






Installation

1. Installation is reverse order of removal.
2. Connect the fan motor connector.
3. Install the radiator upper hose & lower hose, and connect the ATF cooler hoses.
4. Fill the radiator with coolant and check for leaks.
