Fredbird | A/C Compressor Oil | ||

Bought a new compressor for my 91 (Base Model). Will be installing it later this week. or next.
How much oil should I put in it? Have not recieved the compressor yet. Will it say on the compressor itself? I looked in my FSM and did not see the capacity required. Also, since I will be going with R-134A rather than R12 will it be a different amount of oil? Thanks! |

Should say in the FSM the amount of oil to add. At least I thought it did last time I looked. I don't remember off the top of my head.
Since you are doing a conversion, the best bet is to run a cleaner through the whole system, then vacuum it down, check for leaks, and add oil/refrigerant. Which type of oil are you using? Don't forget you need a new accumulator and orifice tube, too. Also, the 134 uses a lower charge than the 12, so fill with 80% of 12 charge. Matthew PS - there are a lot of random postings in the internet about conversions, here is one: http://coloradok5.com/forums/showthread.php?t=273257 |

There is really no exact amount of oil when replacing seperate componets of a AC system. At best it is an educated guess. There is an exact amount number of ounces when replacing the complete system. But, with that said here is some info that will get you close.

I just re-read that site. Those numbers seem a little to me.
Check your underhood sticker for the total amount of oil for the system. Joel |

I have a 10PA20C compressor, so according to the chart, I need 6-8oz of oil.
As to my "Underhood sticker" I think that's long gone. |
