Subject: | Service Information on 2nd Design A/C Compressor Clutch |
Models: | 1995 Saturns equipped with air conditioning and built after and including VIN SZ245875, and all service compressors with part number 21030825. |
On vehicles built after and including VIN SZ245875, a 2nd design A/C compressor clutch (P/N 21031119) is being installed on vehicles. This 2nd design A/C compressor clutch is also used on all service A/C compressors with part number 21030825. The 2nd compressor clutch can be identified by its "smooth" face, versus the face used on the previous 1st design A/C compressor clutch.
The 2nd design A/C compressor clutch will only fit on an A/C compressor with the part number 21030825. This A/C compressor is identifiable by the lack of a thermal switch and new electrical connector location.
The 1st design A/C compressor clutch (P/N 21030300) is still used to service the A/C compressor (P/N 21030811) used on 1991-1993 vehicles, and the A/C compressor (P/N 21030859) used on 1994-1995 vehicles built before VIN SZ245875.
Service procedures for both clutches will be published in the second edition. "1995 HVAC Service Manual."
Important: Tools SA9510AC and SA9506AC are required when servicing the 2nd design A/C compressor clutch.
