L99 (LS-3) Compressor

[ProTouring442]

On my father's '59 Impala we using a 2010 Camaro L99 (LS-3/6L80). We are using the factory Camaro A/C compressor, and need to adapt lines to it. Does anyone know where I might procure adapters/fittings to go on the Camaro compressor?

Thanks!
Bill

Better check with the manufacturer of what ever A/C unit you are going to use to see if that compressor is compatible..........Just say'in....

We made the HVAC from a few different early 1970s GM cars. Nonetheless, their really isn't anything that would make a compressor "non-compatible," save it being unable to move enough refrigerant to keep the evaporator flooded.

The oem LS compressors are variable displacement.

Does your a/c system have a way to control it? That's the reason the aftermarket a/c companies recommend not using the stock compressor. I'm no a/c expert just going on what I was told by Vintage Air. My guess would be the ecu uses pwm to control the compressor based on whatever parameters are set-up in the ecu.

Got ya!

Hmmm.... since the displacement is controlled by the pressure in the high side (Article) and the 2010 Camaro compressor has a clutch, it shouldn't really matter.

I am pretty sure (99%) the compressor we used for our '56 build (1996 Corvette LT4) is a variable displacement as well, and it works beautifully.
