Follow these steps carefully to recharge the A/C system in your GMC Terrain:
Locate the low-pressure service port on the A/C system. This is typically found on the larger diameter line, usually near the compressor.
Connect the A/C recharge hose from the kit to the low-pressure service port. Make sure it clicks into place securely.
Start the engine and turn the A/C to the maximum setting. This allows the system to draw in the refrigerant.
Check the gauge on the recharge kit. If the pressure is low, proceed to add refrigerant.
Open the valve on the refrigerant canister slowly. Monitor the gauge while adding refrigerant until it reaches the recommended pressure level, typically between 30-40 psi.
Close the valve and disconnect the recharge hose from the service port. Be cautious as some refrigerant may escape during disconnection.
Check for leaks by applying soapy water around the connections. If bubbles form, there may be a leak that requires further investigation.
