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. This GM Original Equipment A/C Accumulator is a GM-recommended replacement component and has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

My 2001 Chev 2500hd had a second low port in the accumulator, this part also has it. It perfectly and the OEM original insulation fit as original. Quality, high value for the money, easily installed, appearance looks OEM, performance was as expected.

This was exactly what I needed for my 03 Chevy 3500 6.6L truck. AC is up and running. Be sure to replace the cutoff sensor.

If you're like me and getting multiple sites saying both the 15-20421 and 15-20423 fit your vehicle. Check the spacing between the sensor fitting and the inlet fitting(the one that isn't going in to the fire wall). If your fittings are about 2 or so inches you have a 421. If your fittings are right next to each other you have the 423.
