You may try some stop leak. I wouldn't worry too much about a small leak. So what are you putting in it? Has it been converted to 134a?

Sometimes the el cheapo schrader valve is the culprit.

yes it has been converted to 134a ,and I put a good grade of refrigerant in it ,I was just wondering if it would hurt anything by putting a bottle of that stuff in it every year? thanks Bill

car addict where is the schrader valve located at? thanks

I'm not car addict but they are under the 134a adapters.

Pay me now or pay me later WITH INTEREST. Pay for a professional to find and fix the leak or spend money every so often.

I kind of agree with aklim on this. My point in posting about a schrader valve was meant to say that sometimes really slow A/C leaks aren't much to fix. Last time I had mine professionally serviced it cost me less than $100 all in, and I needed a couple minor parts. On another (not Corvette) car of mine, I did what you do for several years - just added a can now and then. It didn't harm anything. After awhile - maybe 4-5 years - it didn't cool as well as I thought it should. I had actually overcharged it with 134, despite using the cheapo gauges. It also needed a minor check valve.

Those 134a adapters are known to leak.

I know my adapters do...

My thoughts exactly. It won't hurt your car to add a can of R134A every year, but it will hurt your wallet. I say get it fixed properly now, and be done with it.

I've also never seen a leak get better.

If it were me I would probably put some dye into the system and then fix the leak. All the parts are readily available and it is fairly simple to do.

Letting a can a year dissipate into the atmosphere is not going to make a huge hole in our Ozone Layer with your name on it. It is not a "Good" thing but if I had 24 cans of R134 on my shelf I might be tempted to just keep adding Freon. I bought out Trak Auto's supply of R134 at a ridiculous price of less than $1 a can, That stuff has gone up a bit I have noticed... I have a lifetime supply of the R134 as long as they don't rust away first.

I bought a two stage vacuum pump at harbor freight and what a handy tool that has been. I had my mechanic remove the remaining R12 Freon and then I went home and switched it over to R134. You need to get some sealant on most of the threads and they need to be tight and like mentioned before I would install the caps that came with the 134 conversion kit that I purchased. I flushed it out and pulled 28" of vacuum and let it sit for a week or so until I was SURE that it was sealed up. New oil, evaporator and some R134 and we were cranking out lots of cold air out of the system. A/C systems are not that hard to work on, you just need the right tools to do it.

I hope that you find a easy solution for your Corvette!
