Grand Cherokee 2WD V8-318 5.2L VIN Y MFI (1994)
Service Port HVAC: Locations
Two Schrader-Type gauge ports are used with the refrigerant system:
- The High Pressure Service Gauge Port is located on the compressor manifold.
- The Low Pressure Service Gauge Port is located on the condenser-to-evaporator refrigerant line near the back of the engine compartment.
The service port to charge the air conditioning system is located on the condenser-to-evaporator tube near the cowl panel. New service port couplers
have been used to ensure that the system is not accidentally filled with the wrong [R-12] refrigerant. After servicing the refrigerant system, install cap on
service gauge port.
