here is the problem:<BR>during the engine swap all the freon was let out... now it's like 90 degrees here and I need the A/C back. It turns out that my car 92 mx3 has 12 freon, which is very expensive.<BR>is it possible to fill it up with 134?<BR>if not, is it possible to fill up the a/c system yourself?<BR>thanks

You can use 134a as long as the system has been completely evaced.

The two refrigerents (actually i believe it is the oils) don't mix. If you mix the two together then you risk freezing the compressor. A mechanic is going to tell you whatever makes him the most money. You only need the high and low adaptors. Do not overfill the system. I believe the ratio is 80% 134a to R12.

I bought a kit from WallyWorld and did it myself, it's pretty easy. Rent a vacuum pump and the gauges or do like I did, borrow them from a friend.
