My A/C was leaking R134A thru the evaporator. After charging, it would blow cold for about 4-5 days, then slowly get warmer. I was about to spend around $600-700 to get it fixed when I read this thread: https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=19926



Installed the Super Seal on Aug. 20th and it is still blowing just as cold as the day I put it in, about 48 degrees with the temp probe stuck in the vent, with the outside temp at 85 degrees. It did everything it promised to do. This product is guarenteed to work if your system will hold at least a partial charge for two weeks. Previously, mine would hold a partial charge for 10 days. I highly recommend spending the $20 and trying this before spending big $$ on fixing a leaking A/C system.
 
Your friend has the good recommendation as an added sealer will fix it for "awhile", and that is the key word. Breathing any freon at all is not good for you, and the evaporator cools the air that feeds inside of the cab.

Vibration and wear will take its toll on a thin sealer.

Just my . 02









"He recommended that I change the evaporator and accumulator. He is ASE certified. Charged up my A/C and it lasted only four days before it started blowing warm air again. If this Super Seal stuff works, then I'll use it instead of going through the trouble of tearing apart my dash and replacing the A/C parts. TIA for any input. "
 
SteveE,

My ASE certified mechanic friend was the one who put the Super Seal in and checked the system afterward. He had not tried it before, but thought it was worth a shot. I don't think a pin hole size seal would break from vibration. Besides, the sealer remains in the system in a liquid state and hardens with contact with air. If the original seal should start leaking again, more sealer would fill in the hole and seal it right up. It works like Slime does in a tire. I put Slime in all my wheel barrow tires and even with half a dozen thorns in the tire, it doesn't go flat.



As far as breathing in freon, or actually R134A, everyone who had a leaking evaporator would have done that and not found out until their system started blowing warm air. I don't think that doing it once. twice or even three times would pose a health risk.
 
I think when Freon hurts you is when you burn it first, then breath it! I think it turns into fozzeen gas or something like that.



One time I was removing the High side hose on a Dodge van while it was running, and my hand froze so I let go of the fitting. All that R-12 that was comming out of the loose fitting went into the air cleaner intake, then got burnt in the motor. It took me 30 seconds to get out of the garage and I thought I was not going to make it, some real bad stuff!



Anyway, my real question was, "if all these dodges are starting to leak Freon, should I put some of this sealer in my system now before it starts to leak?
 
I paid out the $700~ twice with my last two Dodge/Cummins trucks. One at 54k miles and the other at 89k miles. I like to keep it pure and simple. If I added a sealer into the system and then had to replace the compressor along with the evaporator because the sealer gummed up the compressor, I'd be alittle bummed out. But I am interested in how it works for you in the long run.
