Service Port HVAC: Description and Operation
DESCRIPTION
Refrigerant system service ports are used to recover, recycle, evacuate, charge and test the A/C refrigerant system. Unique sizes are used on the two
service ports for the R-134a refrigerant system to ensure the system is not accidentally contaminated with R-12 refrigerant or by service equipment used
for R-12 refrigerant.
The high side service port (1) is located on the A/C discharge line (2) in front of the engine, below the upper radiator hose (3).
The low side service port (1) is located on the A/C liquid line (2) near the right front strut tower (3). Both the high side and low side A/C service port
valve cores are serviceable.
NOTE: The protective cap aids in service port sealing and helps protect the refrigerant system from contamination. Remember to always
reinstall the protective cap onto the service port when refrigerant system service is complete.
Each of the service ports has a threaded plastic protective cap installed over it from the factory. The service port caps are serviceable items.
