I'm working on a 90 Burb with rear ac.
The compressor froze on me. so when I replace the compressor, I'll convert it to R134
I will replace the accumulater, expansion tube and all the seals, after I flush out the hoses
From the book I have it says it needs 9oz of oil spread out through out the system.If I just add 9oz and not worry about the amount in the evap, and condensor will I do any harm? Thanks
