Coupler HVAC: Description and Operation
REFRIGERANT LINE COUPLERDESCRIPTION
A/C Condenser - 2.4L Turbo Engine:
On vehicles equipped with the 2.4L Turbo engine, a spring-lock type refrigerant line coupler is used to connect the liquid line to the A/C condenser. A secondary retaining clip is installed over the connected coupler for added protection.
The spring-lock refrigerant line coupler requires a special disconnect tool for disengaging the two coupler halves.
OPERATION
Spring-lock Coupler - Typical:
The spring-lock coupler is held together by a garter spring inside a circular cage on the male half of the fitting. When the two coupler halves are connected, the flared end of the female fitting slips behind the garter spring inside the cage on the male fitting. The garter spring and cage prevent the flared end of the female fitting from pulling out of the cage.
