GM Genuine Parts A/C Accumulators are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These accumulators are used in A/C systems with an orifice tube metering device. The accumulator is located between the evaporator and the compressor, and serves to capture and store excess liquid refrigerant. This prevents liquid refrigerant from entering the compressor where it can damage the compressor. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
