Product Details

The Gates Engine Cooling Fan Module line is built for vehicles that rely on electronically controlled cooling fans to maintain consistent coolant temperature. By modulating fan speed instead of running the fan at full output all the time, the module supports efficient cooling control and helps reduce unnecessary electrical load. This makes FCM120 a relevant replacement for Mercedes-Benz cooling system repairs where fan control has become inconsistent or inoperative.

This part cross-references Dorman OE Solutions 902-426 for the same application. Gates FCM120 is also referenced by interchange number 0275456432.

Common Cooling System Issues
