Product Details

The Gates Engine Cooling Fan Module line is focused on controlling electric cooling fan operation with the precision needed to keep engine coolant temperature stable. On vehicles that use electronically controlled fans, the module helps manage fan speed based on cooling demand rather than running the fan at a fixed output. That control strategy supports efficient operation and consistent thermal management across daily driving and stop-and-go conditions.

Gates FCM137 is a fitment-based replacement for select GM trucks and SUVs, including 2008-2013 Chevrolet Tahoe, 2009-2013 Chevrolet Silverado 1500, 2008-2013 GMC Yukon, 2009-2010 and 2012-2013 GMC Sierra 1500, 2009-2013 Cadillac Escalade, and 2010-2016 Cadillac SRX. Use the Gates FCM137 when servicing an engine cooling fan module on these applications.

What This Part Helps Address

• Cooling fan operation that is stuck on or not responding correctly
• Engine temperature that rises when fan control is inconsistent
• Reduced cooling performance during idle or low-speed driving
• Electrical control issues related to the fan module circuit
• Fan speed management problems on GM cooling systems

Installation Notes and Tips

Verify connector style, pin count, and mounting location before installation. This module uses one male connector and does not include a wire harness, so inspect the vehicle harness and terminals for corrosion, heat damage, or looseness before connecting the replacement part. Confirm the original module location and compare the housing dimensions to the removed unit for proper fit.

For best results, diagnose the cooling system as a whole, including the fan motor, wiring, fuses, relays, and temperature inputs, before replacing the module. The Gates FCM137 should be installed on the exact vehicle application listed in the fitment data.

Quality Assurance

Gates is a recognized aftermarket brand with a dedicated Engine Cooling Fan Module product line for controlled electric fan applications. The FCM137 is built to match the electrical and packaging requirements of the listed GM fitments, including Cadillac SRX, Chevrolet Tahoe, and GMC Sierra 1500 applications.
