QuestionHi, I have a leak in the sysytem. The mechanic tried using a dye to find the leak but nothing showed up, so he believes it is the condenser coils, which as you know is an expensive repair job on this vehicle. I have reason to suspect that since the dye was injected in August, it may be possible that over the winter it faded away or got washed off. Is that possible? This is a 15 seater that i converted to a work truck, and i have no need for the rear a/c. I suspect that somwhere along those lines, or the rear condensor may be the problem. Is it possible to cut these lines out and seal the tee? Is there a fitting that would hold up to that psi? Or can they be brazed? By the way the vehicle is a 6 liter with under 40,000k. Thank you.
Answer There is only one condenser in that system so I imagine you are talking about the rear evaporator or lines. Very common problem with these vehicles.
If you google AC line block off kits you will see a plethora of different ones available. You can buy ones that thread right into the existing lines, ones that compression fit over the aluminum tubes adn ones that require a special tool to compress a sleeve over the tube.
I use FMSI ones with the special tool as I am doing repairs every day on many make and models. This also facilites an easy repair as I can select where to block them off. You don't need to re route the AC lines, just make sure you block them off as close to the T section as you can that delivers and returns refrigerant.
Hope this was helpful, here are some links (I don't endorse these companies, just giving you an idea on what you are looking for)
