Detailed Product Overview

Modern cooling systems rely on electronic fan control to match fan output to engine demand. This Gates cooling fan control module processes the fan command signal and adjusts fan operation to reduce unnecessary energy loss while supporting fuel economy. It is a practical replacement for vehicles that use an external cooling fan module rather than a standalone relay setup. The FCM100K1 fits a range of Chrysler, Dodge, Jeep, and Plymouth models from 1997 through 2004, including Jeep Grand Cherokee and Dodge Grand Caravan applications.

This part cross-references Four Seasons 36128 and Suplex 19303 for the same application.
