Service Port HVAC: Description and Operation
Plumbing - Rear
DESCRIPTION
Two refrigerant system service ports are used to recover/recycle/evacuate/charge and test the rear A/C refrigerant system. Unique sizes are used on the
service ports for the R-134a refrigerant system to ensure the system is not accidentally contaminated with R-12 refrigerant or service equipment used for
R-12 refrigerant.
The high side service port (1) for the rear A/C system is located on the A/C discharge line (2), near the right front frame rail (3), in the engine
compartment. The low side service port (4) for the rear A/C system is located on the A/C suction line (5), also near the right front frame rail. Both the
high side and low side A/C service port valve cores are serviceable.
Each of the rear A/C system service ports has a plastic protective cap installed over it from the factory. After servicing the rear refrigerant system, always
reinstall both of the service port caps.
