Review on MASTERCOOL 98234 Socket by Josh Whitehead

I replaced the compressor accumulator diaphragm tube high pressure sensor Low pressure sensor and a new sensor for the back of the compressor New GM Schrader valve and service port/high side fitting You will need a special port to fit the Service to change port senior side. By emptying the old battery into a measuring cup. I used my two-stroke blender cup as it makes fluid ounces and added what came out of the old battery to the new battery. With new Peg 150 ACDelco refrigeration oil. Drained refrigerant oil into new compressor, it measured 4 oz, changed refrigerant oil to ACDelco oil pag 150. I've done this twice on my Chevy Dually 97 and Chevy Tahoe 99, both systems are working great again Ice Cold Air!
