Detailed Product Description

The Four Seasons 46008 fan clutch is engineered for vehicles that use a reverse rotation thermal clutch to regulate airflow through the radiator. With a 6.3-inch maximum diameter, 5.79-inch fan bolt circle, and 3 mounting holes, it is built around the dimensional requirements commonly found in import cooling systems. The aluminum body and standard duty thermal operation provide a practical replacement for worn or failing fan clutch assemblies on Mercedes-Benz models such as the S320, E320, and SL320.

This part number 46008 is a new, non-electronic fan clutch with a flange mount and M6 x 1.0 hole thread specification. It is intended for applications that require a reverse rotation clutch and a 0.95-inch distance from clutch to mounting flange. Four Seasons Fan Clutch products are positioned for direct replacement use where OE-style fit and thermal response are required.

This part cross-references Dorman - HELP 46008 for the same application.
