Removal and Installation

RADIATOR





Removal and Installation

WARNING: Never remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator.

REMOVAL
1. Remove front engine undercover with power tool.
2. Drain engine coolant from the radiator.

CAUTION: Perform when the engine is cold.

3. Remove air duct and air cleaner case assembly.
4. Remove reservoir tank and reservoir tank bracket.
5. Disconnect A/T fluid cooler hoses from radiator.
^ Install blind plug to avoid leakage of A/T fluid.

6. Disconnect radiator upper and lower hoses from radiator.
7. Remove radiator cooling fan assembly.





8. Rotate two radiator upper mount brackets 90 degrees in the direction shown in the figure, and remove them.





9. Lift up and remove the radiator.

CAUTION: Do not damage or scratch air conditioner condenser and radiator core when removing.

INSTALLATION
Install in the reverse order of removal.

INSPECTION AFTER INSTALLATION
^ Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301(J33984)] and radiator cap tester (commercial service tool).
^ Start and warm up the engine. Visually make sure that there is no leaks of the engine coolant and A/T fluid.

Checking Radiator Cap





1. Pull the negative-pressure valve to open it, and make sure it close completely when released.
^ Make sure there is no dirt or damage on the valve seat of the radiator cap negative-pressure valve.
^ Make sure there are no abnormalities in the opening and closing conditions of the negative-pressure valve.





2. Check radiator cap relief pressure.
Standard: 78 - 98 kPa (0.8 -1.0 kg/cm2, 11 -14 psi)
Limit: 59 kPa (0.6 kg/cm2, 9 psi)
^ When connecting the radiator cap to the radiator cap tester adapter (SST) and radiator cap tester (commercial service tool), apply engine coolant to the cap seal part.
^ Replace the radiator cap if there is an abnormality in the negative-pressure valve, or if the open-valve pressure is outside of the standard values.

Checking Radiator
Check radiator for mud or clogging. If necessary, clean radiator as follows.
^ Be careful not to bend or damage the radiator fins.
^ When radiator is cleaned without removal, remove all surrounding parts such as cooling fan shroud and horns. Then tape the harness and connectors to prevent water from entering.

1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downward.
^ Use compressed air lower than 490 kPa (5 kg/cm2, 71 psi) and keep distance more than 30 cm (11.8 inch).

5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
