I did some searching but couldn't find exactly what I needed. This is sort of a reverse AC conversion

Anyway, long story short, 95 4Runner (134A), AC worked perfect when I got it 3 years ago. Then I had to go and kink the AC line somehow while I was changing timing belt and water pump. Got that fixed, AC worked for a while, then started giving issues. Finally decided it was the compressor. Its pretty hard to turn and makes a horrible noise sometimes.

So I got an old R12 compressor (dad has alot of yota parts sitting around), and it turns like it should, so I want to swap it in.

My question to the fine folks at yotatech, is what do I need to do to make that happen? Can I swap the manifold from the top of the 134 compressor to the R12 one, slap it on, and take it to an AC shop for evac and refill, or am I overlooking something?

Taking a road trip to the beach through eastern NC later this week, so AC is going to be crucial (though looks like its going to be in the 80s instead of 100s, so I might would survive)

The R12 compressors convert to 134 fairly easy, so I don't see why this would give you trouble. Just make sure that you preplace your receiver/drier and if there's any evidence of your old compressor failing internally (metal particles/shavings) you'll need to flush everything out.

Oh and take lotsa pics pretty plz. I may have to swap the compressor in my 90 and it looks like it will be a real PITA.

If you are able to make this work and get everything to bolt up, make sure to drain the old oil out of the R12 compressor and replace it with oil for use with R134A. the two oils are different and not compatable with each other.
