1997 olds silhouette: air conditioning..replacing the compressor

Resolved Question:

Hello,

I have a 1997 Olds Sillhouette with front and rear air conditioning. I am replacing the compressor, drier, and orifice tube. I believe the system uses PAG150??? What is the oil capacity of the system, and each part. I purchased the vehicle with the air conditioning not functioning, and there was no R134 in the system when I tried to recover it.

Hello I'm Neal and I am here to help resolve your issue. If I cannot help I will opt out and refer your question to another expert.

-

If this is front a/c only it takes 2 pounds of r134a, make sure not to overcharge it.-

-

Here are the amounts of oil for each component, the parts store can sell you the pag oil GM P/N 12345923 or the equvilent.
Compressor systems require 240 ml (8 fluid ounces) of polyalkylene glycol (PAG) synthetic refrigerant oil GM P/N 12345923 or equivalent. During component replacement and conditions stated, new oil quantities should be added to the system as follows:

^ Accumulator Replaced:
- Add 105 ml (3.5 fluid ounces) to new accumulator.
^ Front Evaporator replaced.
- Add 90 ml (3 fluid ounces) oil.
^ Condenser replaced.
- Add 30 ml (1 fluid ounce) oil.
^ Rear Evaporator replaced.
- Add 60 ml (2 fluid ounces) oil.
^ Rear Evaporator Pipes replaced.
- Add 30 ml (1 fluid ounce) oil.
- If less than 30 ml (1 fluid ounce) is drained, add 60 ml (2 fluid ounces).
- If more than 30 ml (1 fluid ounce) is drained, add same amount.
