Commander 2WD V8-4.7L VIN P Flex Fuel (2007)
Service Port HVAC: Description and Operation
DESCRIPTION
NOTE: LHD model with 4.7L engine shown. Service ports for RHD model and other engines are located in similar locations.
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 receiver/drier (2) near the right side of the radiator (3) and its protective cap is attached to the service port
with a tether strap. The low side service port (4) is located on the A/C suction line (5) near the dash panel (6). 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 protects 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.
