My girlfriend recently bought my brother's '93 XJ 2wd for 500 dollars. The drivetrain is in fine shape, and I'm working on all the little things to get it working just right for her. The problem is the A/C has not worked in at least a year, and it's on r12. I had some credit at the local firestone where I had my 2001 XJ 4x4 worked on, so I had them check it out and they told me the following:
They reccomended converting the system to 134a, but the expansion valve (h-block) was clogged, or not working properly, the reciever/drier had to be replaced, and to convert to 134a I'd need a new condensor because the one on it wasn't "heavy duty" enough to take 134a. ALSO, apparantly someone MAY HAVE mixed the R12 with R134a, because the low side (suction) has a 134a fitting, and the high side doesn't. I'm going to hope for the best and hope that that isn't the case, as I was told it probably ate away at the whole system. They told me the system still holds a seal (for 40 minutes anyway). They estimated ~900 bucks to fix it, so I said I'd do it myself.
Here is what I WANT to do, I need to know if I'm on the right track though.
I want to replace the receiver/drier, and the h block. I would first evacuate the system, flush it, then evac it again (to get the flush out) Then replace the h block, and drier. then I want to put in either 134a or DURACOOL, which i've heard a few good things about. What is my best option? if I go 134a, do I need some sort of orifice tube added, or can I run the system as is? What else do I need to do?
