REMOVAL

WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

1. Remove the following parts:
^ Engine undercover with power tool.
^ Engine cover
^ Air cleaner case (RH and LH)
^ Reservoir tank
^ Radiator core support ornament, radiator core support center and horn
^ Hood lock
2. Remove condenser pipe assembly.
3. Drain engine coolant from radiator.

CAUTION:
^ Perform this step when the engine is cold.
^ Never spill engine coolant on drive belts.

4. Disconnect A/T fluid cooler hoses from radiator. (A/T models)
^ Install blind plug to avoid leakage of A/T fluid.
5. Remove radiator hoses (upper and lower) and reservoir tank hose.

CAUTION:
Be careful not to allow engine coolant to contact drive belts.
