Engine Size: 3.3
I just took an AC class at a Jr. College so items are fresh on my mind, just lacking in experience. I have converted my old 79chevy from R12 to R134, new hoses, comprssor and accum. I then fixed a jeep cherokee with all the same. Both these projects turned out OK and they still work.. Thats a good thing.
New project is a friends Villager, I have not seen it yet. The Villager is a dual system. Have not seen one of these. So, I take it that there are two evaporators and two orfice tubes. Is there like a T or Y under the hood past the condensor that drives both the evaps? I think he talked to the parts houses and there is actually an expanson valve in the rear. We plan on replacing the compressor, accumulator and orfice/expansion valve. I dont know how this failed, so I think it is best to take out the under the hood tube and see if it is clogged. If so, then we will need a new condensor. I need to flush everything. Can I take out exp valve and get to the hoses enough to flush the back part out without having to take things apart? Then flush out everthing up front. Put in new parts, pull a vac and check for leaks. Info I found on this site says 52 Oz of R134 and 11oz PAG. If compressor already has oil in it, find out how much and take away from the 11 oz. If vac holds, then charge with 52 oz of R134. How am I so far? Have I covered everything??? Any tricks or tips??
