This A/C compressor pump manufactured by GM TRUCKS (part number 1136559) is a direct replacement for 1996-2002 CHEVY PICKUP 3500 models. The compressor is belt-driven and fits perfectly in place of the old one.

This was sitting in a old warehouse I bought the box it was already opened

I pulled the plugs out of the holes and seems to be NOS

Doesn’t look used

And wheel spins free

Selling as is
