My suburban has an R134 leak. It works fine when I charge it, but after a week, it stops blowing cold.

Anyone ever use those 134 recharge kits that seal leaks? Do they work?

I know I need to find and fix the leak, but this is bad timing for me to do that.

TIA

My experience has been that they work ok if your leak meets the right conditions. So of them have a dye that will help you located the leak. If you are leaking due to a seal or compressor failure the results are typically not so good. But if you are just looking to get by it might be worth a try. Some of the others might have more information regarding the long term impacts.

Depends how much of a gusher you have. For now, just top it off, it may buy you a few weeks. It's doubtful you have a bad O'ring, chances are it's the evap coil leaking. UV dye and the special black light flash light will confirm this.
