New AC Compressor install help
Hi Guys and Dolls, I need your expert advice once again while trying to finish up getting my 72 Corvette back on the road again.
I recently reinstalled the original and newly rebuilt water pump and fan clutch. I also reinstalled the original and newly rebuilt AC compressor too. on the AC compressor: I’m looking at my AIM manual sheet E1… it says “CAUTION do not install connector (electric) to compressor until after the system has been leak tested “. Does this mean I cannot run the engine with the electric wires plugged into the compressor until I am ready to see if the ac system will hold a vacuum? Right now I just installed my newly rebuilt ac compressor into the car with correct fan belt attached. I also attached both wires to the compressor. The compressor has only had the correct amount of oil installed in it.
Can I run the engine with both wires connected to ac compressor and not hurt the compressor if there’s no R12 installed yet?
Thanks. Joe in New Hampshire

Yes, as long as you don't turn the a/c on you should be okay. The compressor will not run unless you turn the system on with the a/c controls. But you can always leave the connector unplugged too, so that there is no chance of engaging the a/c since the electrical will be unplugged.

I don't know how much you know about working on a/c systems, so it's difficult to know how much help you need. Anyway, if you plan on charging the system yourself, (installing refrigerant), you'll will need a vacuum pump and a/c gauges to do so. In addition to evacuating the system, which is required prior to adding refrigerant, you can use the pump as a leak detector. Simply put the system under a vacuum and see if it holds overnight. If it holds, the system should be leak free.
I can offer more help, but as stated, I don't know if you need it. If you don't, let us know and I'll keep my 2 cents to myself. Good luck.
