Connection point for female-side piping is thin. So, when inserting male-side piping, take care not to deform female-side piping. Slowly insert in
axial direction.

-

Insert one-touch joint connection point securely until it clicks.

-

After piping has been connected, pull male-side piping by hand to make sure piping does not come off.

-

When recharging refrigerant, check for leaks.

NOTE:

-

When filling radiator with coolant, refer to "Changing Engine Coolant".

-
