Product Details

The Gates Engine Cooling Fan Module line focuses on controlling electric cooling fans with the accuracy needed for modern thermal management systems. On supported Audi vehicles, the module helps the fan respond to engine temperature demands rather than running at a fixed speed, which supports consistent cooling system operation and efficient electrical load management. This Gates FCM115 unit uses a female connector layout, a steel/plastic housing, and an included harness for the specified applications.

This part cross-references Dorman OE Solutions 902-435 for the same application.

What It Helps Address

• Cooling fan not responding to temperature changes
• Fan running at the wrong speed
• Engine temperature fluctuations in traffic or idle conditions
• Cooling system warning lights related to fan control
• Electrical fan control faults on Audi A4, A4 Quattro, S4, A6 Quattro, S6, and Allroad Quattro models

Installation Notes

Verify connector count, pin layout, and vehicle fitment before installation. This module is listed with 2 connectors, including a 6-pin connector and a 2-pin connector, so matching the original configuration is important for proper operation. Confirm the application against the vehicle’s cooling fan control system on 1998-2005 Audi models before replacement.

Quality Assurance

Gates supplies this engine cooling fan module as a service replacement for supported Audi cooling systems. The part is engineered for the listed fitments and built to match the electrical and physical requirements of the original application.
