Detailed Description

This One Stop Solutions condenser is designed for vehicles that need a direct-fit replacement A/C condenser with OE-style dimensions and performance. Part Number 4005 uses aluminum parallel flow, serpentine, or tube-and-fin construction depending on configuration, with bonded fins and tubes to improve heat transfer. It is a practical choice for restoring cooling efficiency on Cadillac DeVille, Cadillac Fleetwood, and Cadillac Commercial Chassis applications, as well as select Buick, Oldsmobile, and Pontiac models listed below.

This part cross-references APDI 7014005 for the same application.
