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.
