Hi,

The a/c system in my 240d has the compressor removed but the rest of it is there.

I have located compressors for the year, make and model of my car on several websites. None of the applications say if they are designed for r12 or r134. Are those compressors made for the old style r12 refrigerant or will they work with either r12 or r134?

Do the new receiver dryers, accumulator, condenser, expansion valve, refrigerant oil, refrigerant hose, a/c system o-rings and seals work with either r12 and r134? Are all of these parts interchangeable?

I was thinking I could replace the compressor, receiver dryer, condenser, expansion valve, use the old hose, replace the o-rings (I assume the seals and o-rings are the same for r12 and r134), and have it charged with r12.

Just starting this project. Thanks.
