Spring Lock Coupling
When disconnecting or connecting spring lock couplings, observe the following.
-
When the coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the cage of the male fitting.
-
The garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage.
-
Three O-ring seals are used to seal between the 2 halves of the couplings.
-
Use only the O-ring seals listed in the Ford Master Parts Catalog for the spring lock coupling.
-
A plastic indicator ring is used to indicate, during vehicle assembly, that the coupling is connected. Once the coupling is connected, the indicator
ring is no longer necessary but will remain captive by the coupling near the cage opening.
-
The indicator ring may also be used during service operations to indicate connection of the coupling.
-
An A/C tube lock coupling clip is used to secure the coupling and is required.
