MBdiesel, Thank you. I recharged per your directions and all seems to be working as hoped. I still have to find the leak but at least I know the basic system is OK. The Interdynamics kit I bought came with a charging hose and a pretty rudimentary guage. I charged until about the middle of the "safe" zone. Nice clod air, don't know for how log but should be easy for an A/C shop to find the leaks. Thanks Much for your reply and advise. I let the can sit sort of near the radiator to warm it up a bit, worked pretty good.
