Removal and Installation
1. | Disconnect the battery negative terminal.
2. | Remove the air cleaner assembly. (Refer to Intake and exhaust system - "Air Cleaner")
3. | Loosen the drain plug, and drain the engine coolant. Remove the radiator cap to drain with speed.
4. | Disconnect the over flow hose (A) from the radiator.
5. | Disconnect the radiator upper hose (A) and lower hose (B).
6. | Disconnect the ATF cooler hoses. (Refer to Auto Transaxle System - "Auto Transaxle")
7. | Remove the front bumper. (Refer to Body - "Front Bumper")
8. | Remove the head lamp. (Refer to Body Electrical System - "Head Lamp")
9. | Remove the upper mounting bracket (A).
10. | Disconnect the cooling fan controller connector (A).
11. | Remove the air guard (A) and then disconnect the A/C condenser (B) from radiator.
12. | Disconnect the radiator assembly from vehicle.
13. | Remove the cooling fan & reservior tank (A) from the radiator (B).
14. | Install in the reverse order of removal.
15. | Fill the radiator with coolant and check for leaks.
16. | Put the radiator cap on tightly, then run engine again and check for leaks.
Inspection
Radiator Cap Testing
1. | Remove the radiator cap, wet its seal with engine coolant, and then install it on a pressure tester.
2. | Apply a pressure of 93.16 ~ 122.58kpa (0.95 ~ 1.25kg/cm², 13.51 ~ 17.78psi).
3. | Check for a drop in pressure.
4. | If the pressure drops, replace the cap.
Radiator Leakage Test
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.
Check for engine oil in coolant and/or coolant in engine oil.
