Looking for a run down on what normaly goes and sugestions on how to fix based on past experiance.

Mine has no pressure in the system, so I would assume it leaked out.

I'm tempted to try one of those seal and recharge kits you can get at the local parts store.

Anyone had luck with this?


Thanks

If you have zero gauge pressure then a seal kit won't help as you have a massive leak.

+1^ You need to pressurize with nitrogen, find and repair the leak, replace the drier. Then you need to decide which refrigerant you want to charge the system with.

What year car? The AC systems for pre-85 and 85.5 on are different. If it has been empty for a while chances are you will need a dryer and expansion valve in addition to fixing the leak.

usually the seals that go from the lines to the compressor body start leaking from the vibration. Cant hurt to put two new o-rings on the lines at the compressor-use alittle oil on them before install- and then pressurize and leak check. You'll need to vac down the system and recharge 2lbs r12 or change the oil in the compressor and use 134a. "should" get a new drier but ive had luck the cheap way by not doing it.

I'm in the same boat. My system has a slow leak. I put a can of R134A in about every two months. I've done the soapy water test and dye without success. I'm going to try a product called "Super Seal Premium," by Cliplight MFG. it has a very high success rate according to all of the reviews I've seen. It stays in a gas form in the system and only solidifies at the leaking area, so it, supposedly, will not clog any component in the system. You have to follow the instructions to the "T" in order to get good results. I have manifold gauges and a vacuum pump so that shouldn't be a problem. They also have a product called "Total Seal" which has a drying agent so you aren't supposed to need to change the drier/receiver or pull a vacuum. I'm a little skeptical on that one. Anyhow, I haven't seen a bad review on the Super Seal yet, other than it didn't seal a huge honkin' hole in someone's condenser. I'm going to try it this weekend. If it doesn't work, so be it. We only need A/C for three months here in the Northeast

I wouldn't contaminate the whole system with that Snake Oil. Find the leak, replace the O-rings as suggested, use an electronic sniffer to check for leaks. They can detect an ounce a year leakage rate. You have a massive leak.
