A/C Ports

The A/C Charge Port Valve (Low Side) is on top of the Suction Accumulator Drier which is the metal cylinder at the rear of the passenger side of the engine compartment. The A/C Charge Port Valve (High Side) is at the front of the driver side of the engine compartment (near the battery). The fittings on a modern R-134a system are not the same for High and Low pressure. If you buy one of the self contained recharging systems (like Arctic-Freeze) it will only attach to the low side.
