With Automatic Climate Control

Refer to "Precautions for Refrigerant Connection".
A plastic indicator ring is used on spring lock couplings during vehicle assembly to indicate that the coupling is connected. After the coupling is connected, the indicator ring is not necessary but will stay near the cage opening.

REMOVAL




1. Discharge refrigerant from system. Fit spring lock coupling tools (9.53 mm [3/8 in], 12.70 mm [1/2 in], 15.88 mm [5/8 in] or 19.05 mm [3/4 in]) to the coupling.




2. Close tool and push into open side of cage to expand garter spring and release female fitting.
If the tool is cocked while pushing it into the cage opening the garter spring may not release.




3. After garter spring is expanded, pull fitting apart.




4. Remove tool from disconnected coupling.

INSTALLATION




1. Check to ensure that garter spring is in cage of male fitting. If garter spring is missing, install a new spring by pushing it into the cage opening. If garter spring is damaged, remove it from cage with a small wire hook (do not use a screwdriver) and install a new spring. Check for burrs on the end of the male tube to avoid scratching the female tube.




2. Clean all dirt or foreign material from both pieces of coupling.
3. Install new O-rings on male fitting.

NOTE: O-rings are made of a special material. Use only the specified O-rings.

The use of any O-ring other than the specified O-ring may allow the connection to leak intermittently during vehicle operation.

4. Lubricate male fitting and O-rings and inside of female fitting with clean lubricant. Check for scratches on the inner surface of the female filling.







5. Install plastic indicator ring into cage opening if indicator ring is to be used.
6. Fit female fitting to male fitting and push until garter spring snaps over flared end of female fitting.
If plastic indicator ring is not used, it will snap out of cage opening when coupling is connected to indicate engagement.
7. If indicator ring is not used, ensure coupling engagement by visually checking to verify garter spring is over flared end of female fitting.
