compressor itself? I know a few of you tried this when I brought it up before, I'm now just getting around to trying it. I know there are 2 fittings I need to change. It's amazing that Haynes and the FSM don't mention the AC system, and the only 2 I have spotted are on the compressor itself. Just trying to get it right.
Thanks.
Thanks.

Theres a certail percentage of freon you have to use when you go from r12 to r134a. I THINK you use 80% of 134a at the R12's capacity.
Also be sure to change out the accumulator on the system, so its good and clean. Part that is in front of the radiator

just did the retrofit using a kit from a local autoparts store...about $30...also bought an ac leakstop bottle for less than $5.
All I had to do is to screw an adapter on the compressor (the "S" side, thicker pipe, mine was the one closer to the fender as I looked down on it)...did the leak detector / stop leak bottle (no problems), then followed the AC fill directions (2 bottle of R-134a, then a bottle of oil) and the AC was blowing stong.
FYI...I had an empty AC system (i.e. no R-12) to start, so I did not need to get that out / recovered...
This sure beats doing a fillup with R-12 - that is if you can find someone to do it!
Good luck...

Enlighten us, how cheap is this part. I think new ones for a early '80's GM vehicle I did this to costed $75. Just imagine what a "genuine Mazda" part would cost.

Thats cool. Ofcourse, it takes a few weeks or more to know that it won't leak out really. Those retro kits are a gamble if you don't have the whole system apart to get the R-12 oil out and new 0-rings also to get a well done retro-fit done. But R-134a is a bit cheaper so, recharging it couple times a year is no big woop.
