A/C questions

[04 Venom]

My daily driver probably has a leak in the evaparator coil and I am trying to avoid the time and expense of taking the dash out to fix it. My question is this: does anyone have experience using some sort of sealer injected into the a/c system to plug the hole? I know such products exist, but I don't know if they work. Any advice would be appreciated.

What car?

I don't have direct experience with a sealer like that, but I guess the worst thing would be it doesn't work. Then replace the evaporator anyway.

Bigger question, I would think, is could it do any harm to the rest of the system.

my grandpa used to say if its not worth doing it right the first time its probly not worth doing it at all

Super seal is the ONLY sealer I've had good luck with, if its a real big leak it probably won't help. Autozone sells it...

Its a 13 year old Focus ZX-3.

Good point about checking on potential harm to the other components.

I wouldn't try it. You have a 13 year old system that is not what it use to be. The book calls for 7hrs to do the whole job. I say have someone suck out the system, do the swap on a saturday and have it sucked down and recharged. Then your back to having a working system by monday.

I have gauges and a vacuum pump if you need one.

Very kind of you, but I lack experience to work on a/c.

Can you smell freon in the vents? Might just be a rock in the condensor. Id have it vacuum tested. Shoot me a pm and i can test it for you.
