KHE Posted June 22, 2010 Report Share Posted June 22, 2010 Use plain refrigerant, nothing with additives, o-ring conditioner, sealants, etc. If there is a leak, fix the leak. Use a manifold gage set when charging the system. When charging a system that has been empty, pull a vacuum for at least 45 minutes and charge into the vacuum. One could write a book on the do's and don'ts - many have. Is there a specific A/C issue you're working on?

Rocco Mattero Posted July 21, 2017 Report Share Posted July 21, 2017 2001 eldorado, just got the " low refrigerant / a/c compressor off " message! I haven't been using the a/c because a noise in the blower motor when on High. But I wanna try and charge it to see what happens? Where do I start!
