Product Details

The Gates FCM156 is built for vehicles that use an electric cooling fan module to manage engine temperature more accurately than a simple on/off relay. By modulating fan speed, the module helps the cooling system respond to changing engine load and operating conditions while limiting excess energy use. This part is listed for 2018-2019 Hyundai Sonata models, and the fitment data identifies the application as an engine cooling fan module. This part cross-references 25385D4200 for the same application.

Common Problems It Can Address

• Cooling fans running at the wrong speed or not responding correctly
• Engine temperature fluctuations caused by fan control faults
• Cooling fan operation that stays on longer than expected
• Diagnostic trouble codes related to fan module performance
• Reduced cooling system efficiency on a 2018-2019 Hyundai Sonata

Installation Notes

Verify connector style, mounting location, and OE part number before installation. The Gates FCM156 uses 2 female connectors and does not include a wire harness. Confirm the module matches the vehicle’s cooling fan control setup on the 2018-2019 Hyundai Sonata before replacement. Clear any stored fault codes after installation and test fan operation through the full temperature range.

Quality Assurance
