Product Details

The Gates Engine Cooling Fan Module line is built for vehicles that rely on electronically controlled fan operation to keep engine coolant within a steady temperature range. By managing fan speed instead of running the fan at full output all the time, the module helps the cooling system respond more precisely to engine demand. This FCM120K unit cross-references Dorman OE Solutions 902-426 for the same application and also references Gates FCM120.

These Mercedes-Benz cooling fan module applications are commonly searched by drivers needing an OE-style replacement for fan control faults.

Common Problems This Part Can Address

• Cooling fan stuck at one speed or not responding correctly

Installation Notes and Tips

Verify the connector style, pin count, and amperage rating before installation. Confirm the vehicle uses a 12-volt cooling fan control setup with a female 5-pin connector and compare the original module to the Gates FCM120K for match-up on the listed Mercedes-Benz applications. Inspect the harness and surrounding cooling system wiring for heat damage or corrosion before completing the repair.
