REMOVAL

WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from water outlet (front). 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 under cover with power tool.
^ Engine cover
^ Air cleaner case (RH and LH)
^ Reservoir tank
^ Hood lock cover, hood lock stay assembly and horn
