Re: Converting factory AC to use R134a
Quote:
I have a couple of questions if someone could address them:
- Would an AC shop need to pull apart under my dash, or in the heater core area that would require pulling a fender? I have brand new paint. It looks like the inboard section of the underhood HVAC box comes off. But are all the parts in there?
- When I buy a new pump and dryer from LMC, as I did, it has some oil in it. Would that be the old style or new? I poured it out but did not flush it.

What parts? The underhood box has the evaporator in it. Expansion valve and POA are connected to the evaporators inlet and outlet outside the box. There's also a door between the core and blower motor. It's control shaft sticks up out the top of the box.
I always replace the oil shipped in the compressor. There shouldn't be any need to flush it out.
