Automotive Air Conditioning Information Forum

With all due respect, I never said that I was ripped off. I sought the help of the forum to get to the heart of the matter, correct any errors, and get my car proper attention. This has been a learning experience. Thanks for all the positive input.

I think I got it. If the car is not converted to R134a, which is the case, the shop MUST use R-12 Refrigerant and the compressor MUST be flushed with 525R-12 Oil and then filled with that oil.

The system was flushed to remove any shards and a new condenser was installed as well for the same reason. Concerning the oil/refrigerant, what type (specs) of oil or refrigerant is required r for this R4 Style; w/ 9 O'Clock Coil; Piston Compressor? The problem was probably related to those.

This is a licensed shop and was highly recommended. Reading your comments I lean towards a faulty installation procedure due to lack of knowledge of classic cars or lack of proper supervision at that shop. Thanks for your comments. They have been very helpful so far.

Because the compressor is totally damaged I can return it to Rock Auto and get a replacement. The requirements to honor the warranty are strict though.

The car is original. Has not been converted in any way.

The compressor was new, not remanufactured. I bought it in Rock Auto to specifically fit the 1988 Cutlass Supreme Oldsmobile. As advertised, it was supposed to be factory oiled. As for the installation it was done by a technician. Thanks for your responses so far.

The technician installed a new compressor on my car and it immediately started making noises and stopped cooling the car. The technician says that the compressor is damaged and needs to be changed. Also changed were all belts as he claimed they needed to be changed. The car is a 1988 Oldsmobile ...
