Removal and Installation
WARNING: Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully remove the radiator cap by turning it all the way.
NOTE: When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
- Drain coolant from radiator. Refer to CO-11, "Changing Engine Coolant".
- Remove hoodledge covers (LH/RH).
- Remove front bumper fascia. Refer to EXT-16, "Removal and Installation".
- Remove battery tray. Refer to PG-68, "Removal and Installation (Battery Tray)".
- Disconnect reservoir hose.
- Disconnect radiator hose (upper) and radiator hose (lower).
- Remove A/C condenser. Refer to HA-45, "CONDENSER : Removal and Installation".
- Disconnect the CVT oil cooler hoses

CAUTION: Do not spill coolant in engine compartment. Use a shop cloth to absorb coolant.
- 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 on-vehicle, remove surrounding parts in order to access the radiator core. Tape the harness and electrical connectors to prevent water from entering.
- Spray water to the back side of the radiator core using a side to side motion from the top down.
- Stop spraying when debris no longer flows from radiator core.
- Blow air into the back side of radiator core using a side to side motion from the top down.
- Use compressed air lower than 490 kPa (5 kg/cm2, 71 psi) and keep distance more than 30 cm (11.8 in).
- Continue to blow air until no water sprays out.
- Inspect radiator for leaks as follows:
- Apply pressure using Tool.
Tool number : EG17650301 (J-33984-A)
Leakage test pressure : Refer to CO-27, "Radiator".
WARNING: To prevent the risk of the hose coming undone while under pressure, securely fasten it down with a hose clamp.
Attach a hose to the oil cooler as well.
- Check for leaks.
