A/C - Refrigerant oil question
I have a '92 Bonneville SE, original AC. I'm going to replace the main 'hose' harness (condenser/pump/accumulator) along with the expansion valve and a new accumulator. The AC pump (DA6, i think) is original. I'm leaving it R12, as refrigerant is not a problem. Would anyone know how much mineral oil the system is supposed to hold? I've read that if you empty the contents of the accumulator and add 2 oz, that would be sufficient; however, i've added a few 'oil shots' over the years (2 oz R12 and 2 oz oil, in a can). I'm afraid of 'over oiling' the system if i follow this procedure. What I'd like to know is the factory recommended oil charge (if i had to guess, i'd say around 6 oz.) AND how much the compressor holds (if any) as an adjustment to the amount. I'm not expecting to clean/flush the system, as the compressor is still good (shouldn't be a need to flush, as i've only flushed when the compressor gives up the ghost).
Any 'hep' would be appreciated.
