How do you add freon to 1992 Chevy truck 1500?

Answer 1

To add Freon to a 1992 Chevy Silverado 1500, first ensure the engine is off and the AC system is not running. Locate the low-pressure service port, typically found on the larger diameter aluminum line near the firewall. Attach the refrigerant can's hose to the port, then start the engine and turn the AC to maximum. Add the Freon slowly, checking the pressure gauge on the can, until it reaches the recommended level, then disconnect and securely replace the service port cap.
