Service Port HVAC: Service and Repair

The service port valve ports are located on the A/C liquid line (high side) and suction line (low side).

REMOVAL
1. Remove the valve caps. Remove refrigerant from A/C system using a refrigerant recovery machine.
2. Using a standard valve core tool, remove the valve core. Be careful to prevent any dirt/debris from entering the valve core opening or getting on the replacement valve core.

CAUTION: A valve that is not fully seated can lead to damage to the valve during evacuation and charge. This can result in system refrigerant discharge while uncoupling the charge adapters.

INSTALLATION
- For installation, reverse the above procedures. Evacuate and charge the A/C system.

NOTE: When assembling the new valve core into the manifold, the core should be oiled with clean ND8 PAG compressor oil.
