Re: New 7h15 Sanden compressor defective?

"I discovered that the pressure switch is not activating the High fan speed" This will definitely impair the system. Sounds like your flushing method was quite acceptable. When you say the refrigerant is 137a, do you mean to say 134a? "Now what intrigues me most is the compressor is c...

Re: 53 Packard Patrician factory AC

"Crank pulley OD 6.75", OE idle speed is 450 rpm but I can bump it up to what the compressor would need." Please remember that if you have the idle set too high on a stick shift that you will have a lot of trouble shifting it...you will get a lot of grinding. Try it ahead of time befo...
