CONDENSER

12. Release radiator maintaining pawls, then pull-up the condenser assembly to release it from radiator. Refer

to

CO-13, "Removal and Installation"

(HR engine models) or

CO-35, "Removal and Installation"

engine models).

13. Maintain radiator pushing back.

14. Pull upward to remove condenser.

CAUTION:

Take care do not damaged condenser or radiator.

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

• Replace O-rings of high-pressure flexible hose and high-pressure pipe 1 with new ones, and then

apply compressor oil to it when installing it.

• Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping

straight in axial direction.

• Insert piping securely until a click is heard.
• After piping connection is completed, pull male-side piping by hand to make sure that connection

does not come loose.

• When recharging refrigerant, check for leaks.
