Hi all, If anyone has 1 or 2 cans of R-12 they wouldn't mind selling, please let me know off-list - thanks!!!
As an update to my A/C question last week, I plugged in my gauges on my buddies' 300E yesterday. There was 15psi in the system, less than I'd like, but not totally dead. We decided to gamble on putting a pound of R-12 in the system. I put in about 12oz, and the system started working on its own, no need to short the low-pressure switch. It was blowing cooler air out the ducts, too. He has the old 'green' fan switch and high side pressures were getting to 250psi and climbing (doesn't trigger until 300psi), when disaster struck. My old gauge/hose set decided to spring a dozen pinhole leaks on the high side hose and spray a cloud of you-know-what. I unscrewed the fitting as fast as I could, I'm sure we didn't lose much, but I had no other hoses so our experimenting was done for the day. Anyway, it looked promising, as the system was working and might be OK if just charged up. He's back home now and I may not see him again for a few weeks/months. He's got an R-12 can tap, but no cans of R-12. I think 1 or 2 cans should do the trick to get cold air again (system spec is 2.4 lbs). :-) -- Dave M.
