How to Recharge Your CarAC: Includes AC Pressure Chart

Determine Ambient Air Temperature. If the temperature of the air is 55°F or below, do not charge the vehicle. It is also always recommended to use a charging hose with a gauge. Locate the Low-Side Service Port. This port is typically found on the line connecting the accumulator and compressor. The high side fitting is located between the AC compressor and condenser and is the larger of the two fittings. Wipe Away Dust. Wipe away any dust with a clean rag and then remove the cap from low-side service port. Attach the Charging Hose. Attach the charging hose to the low-side service port and ensure that you have a secure connection. If the hose does not attach easily you may be using the wrong port.
