Have a 93 Allante, date of manufacture Oct 92, AC compressor dated June 02. I have been looking for three days for an AC compresor with the correct bolt up patterns, and connection lines and electrical. After many photos and eMails I have yet to find the right compressor. My compressor is has these numbers: 1136027, 051821 HR6 H. People who say they have the same unit, but on picture inspection the bolt up and mount positiions, and hose hook up points are differant. I would like to get the correct compressor or a complete rebuilding kit. My compressor only has the same milage as my car, 19k+. Thanks for any help. Marty
There were two different compressors used in 1993 Allante's. You should be able to tell from the GM database which type based upon seeing a V4J option code on the sticker in the trunk or lack of same. But I just ran into a case where the Cadillac database was wrong and we shipped the wrong compressor. We keep both of them in stock.
