smokin5s Posted May 20, 2017 Author Report Share Posted May 20, 2017 it's bone dry, I thought you had to use a vaccum pump to fill it if it was completely empty... am I wrong? Quote Link to comment Share on other sites More sharing options...
Mace1647545504 Posted May 20, 2017 Report Share Posted May 20, 2017 I've had dead a/c and charged it before> I don't know if it was dead dry, but I really don't so maybe you do. I will defer to someone who really knows..I'm just cheap..lol mace Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 20, 2017 Report Share Posted May 20, 2017 By pulling a vacuum it not only ensures the system is sealed, but by pulling a vacuum long enough eliminates moisture in the system. I have no idea why your system is dry, but if it's cheap you're going for I really don't know if it was fixed properly. So ramming some cans of freon in it will just keep up the idea of cheap and careless. Quote Link to comment Share on other sites More sharing options...
smokin5s Posted May 20, 2017 Author Report Share Posted May 20, 2017 my system is dry because I pulled the compressor because it was rusted out and wouldn't spin making a horrible grinding noise when the car was running. Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted May 20, 2017 Report Share Posted May 20, 2017 It needs to be vacuumed down then to get the moisture out of the system. You can get a cheap vacuum pump from horrible freight and vac it down then use the cans to top it off. Idk where the oil is held in those systems, you may need to properly top the oil off to (if it was not in the compressor then there should be nothing to worry about).

Forrest Gump 9 Posted May 20, 2017 Report Share Posted May 20, 2017 Since we're on the AC subject. My compressor is leaking freon out the back plate. If the freon is in the system, it blows cold. As soon as the freon is out, it blows warm. Can the compressor repairable? Quote Link to comment Share on other sites More sharing options...

craig71188 Posted May 21, 2017 Report Share Posted May 21, 2017 my system is dry because I pulled the compressor because it was rusted out and wouldn't spin making a horrible grinding noise when the car was running. 1) You probably have metal shavings all through the system unless you flushed it, they will likely find their way into the new compressor and damage it. 2) If you didn't replace the accumulator/receiver dryer, the desiccant will be shot and will not work to keep the system dry 3) If it is an orifice tube system, this too is likely plugged with metal shavings Slapping a compressor on and throwing refrigerant at it is a sure way to spend more money replacing the compressor again (and again) until you REALLY fix the system.
