Over the years there are updates to parts just like thereare to car models. For every model year that a vehicle is in production thereare small changes that are more than skin deep. The AC compressor just like other automotive AC parts may change as the years go by. Sometimes a car company goes under andthe aftermarket has to take over the production of the replacement parts. Inthe case of Saturn that is exactly what happened, when the company closed itsdoors it left many of its vehicles owners out in the cold when it came toparts. Maybe out in the cold is the wrong term to use, out in the heat isbetter since the OEM AC compressor was no longer available the aftermarket didwhat it could.
The solution to the lack of supply was to find a compressorthat bolted into the same location as the original Saturn compressor. This isnice in theory but the problem arose when a compressor was found, the compressorcould bolt on but the AC lines would not hook up. The solution was found injust changing them out and sending the update out whenever a Saturn L series orVue compressor was sold.
Each one of the replacement compressors was sold with a setof the high and low side ac lines what could be easily swapped into the system.This simplistic fix is a great example of how the aftermarket is not just abunch of cheap parts but more a community of vendors who are working to createa market for anything that has a need.
