I have an AC leak somewhere in my system. I have put ARTIC FREEZE and AC Pro in there only for it to go away in a few days. Before I did those, I took it to a repair facility and they put Freon with a Dye it in but never found the leak.

Can someone help please.

 

If they couldn't find a leak with dye then they didn't put enough in or they didn't circulate it enough.
You may have to do it yourself, UV dye kits and not too expensive, under $60.

I assume you don't smell anything in the cab so leak will most likely be in engine lines or condenser in front of the rad, you may need to pull the rad to get a good look at the back side of condenser after running the dye thru the system.

 

Thank you for your reply.
Nope, I don't smell anything, I guess I will go and get a can of Freon with UV Dye and look myself.

Thanks again for the reply.
