ISSUE:
A procedure has been developed for cleaning Spring Lock Coupling (SLC) refrigerant fittings during air conditioning system repairs. This procedure and
replacement of black O-rings with the improved green O-rings will reduce the potential of refrigerant leaks.
ACTION:
When servicing the air conditioning system on the subject vehicles, or if a refrigerant leak is suspected at any of the SLC connections, disconnect all
SLC connections and replace all black O-rings with new green O-rings which are made of an improved material. Use the following service procedure to
clean the coupling before installing new green O-rings. Refer to the Parts Block in this article for correct parts usage.
CLEANING PROCEDURE
1.
Remove all refrigerant from the vehicle A/C system using an U.L. approved Refrigerant/Recovery device prior to disconnecting the refrigerant
couplings. Refer to the appropriate model year Service Manual for a detailed A/C discharging procedure.
2.
Disconnect the SLC coupling.
