Bought a 2002 TJ and want to recharge the a/c. Not sure what Freon is in the system. What kit should I buy?
Don't you think after 10 or 15 years you'd need a little recharge?

My '00 had no cold air blowing when I bought it so 17 years old now, and I used one bottle of E-Z Chill off of Amazon for $18 and it now works perfectly and is ice cold for the first time. The stuff works great, and comes with a halfway decent gauge so you can see where your levels are before and after.Bought a 2002 TJ and want to recharge the a/c. Not sure what Freon is in the system.

What if I can’t find an AC leak even with the Mastercool Professional UV Detector Kit? I was low on refrigerant according to the gauge. I added some, cranked the Jeep on max air. Finally got pretty cold air. Within a week it will be warm again. So after recharging I added some of the UV dye and ran the Jeep and max ac for 10-15 min. Can’t find anything with my UV light. I thought maybe it’s a slow enough leak that it won’t show up for a few days. Thought I’d keep running and checking it. Any other suggestions? Does part of the system pass through the firewall into the cab? Could there be a leak in there?

I to have a leak somewhere I can't detect. Expecting the leak is at the evaporator because I can't detect it with the dye.
To answer your questionYou could have a leak inside the cab in the evaporator. It would have to be a crack or very small hole, maybe from rubbing or something. The connections to the evaporator lines are on the engine side of the firewall. As TJ4Jim said dye is not always a cure all. Used a lot in the automotive field though, and on the whole fairly successfully. I used nitrogen on the farm equipment a/c systems, and that is what we use at work. I realize that not everyone will have a nitrogen bottle in their garage. And I also realize that at $100.00 plus shop rate per hour, one might be reluctant to visit a repair shop. One of the things I like about nitrogen is you can crank up the pressure, shut the valves and see if it will hold, if not using snoop or soapy water you then start looking for bubbles, often with a mirror on the under side of fittings or solder joints. In theory you should be able to do the same with dye, but not always in practice. We hired some very good automotive techs a few years back and they were skeptical of nitrogen, never heard of it. Now it is all they use. If all else fails I would recommend finding a good a/c shop that uses it.
