Product Details

The Four Seasons PAC-Kit line groups the compressor service components needed for a focused A/C repair on the listed 2006 applications. This 1771R kit is specified for vehicles with a 10S17F compressor or, on one listed Sierra 1500 application, a 10S20F compressor, along with the noted tube diameter and drier clocking requirements. For 2006 Cadillac Escalade and Escalade ESV/EXT, the listing calls for front A/C service without rear A/C. For Chevrolet Silverado and GMC Sierra applications, the notes call out the matching orifice tube and drier configuration required by each platform.

This part cross-references 77377 and 83239 for the same application.
