AdvanEX Engine Cooling Fan Control Module for Ford Edge/Flex/Crown Victoria 940002904 Replace OE — Direct Fit, Variable-Speed

The AdvanEX Engine Cooling Fan Control Module is a direct-fit replacement that controls radiator fan speed for efficient engine cooling on compatible Ford, Lincoln and Mercury vehicles.

This replacement cooling fan control module restores correct fan operation by managing the fan motor’s variable speeds to match engine load and temperature demands. Designed to match OE fit and connector arrangement, this module is compatible with multiple Ford platform engines and replaces OE part numbers such as 940002904, 6W1Z8B658AC and 6W1Z8B658AB. It helps the vehicle maintain stable operating temperatures while preserving fuel economy and electrical system reliability when installed correctly.

Which vehicles is this cooling fan module compatible with?

This AdvanEX unit fits a range of Ford, Lincoln and Mercury models across several model years and engine sizes. Always verify your existing part number and connector shape before purchase to ensure fitment.

• Ford Edge 2.0L (2012–2015), 3.5L (2007–2015), 3.7L (2011–2014)
• Ford Flex 3.5L (2010)
• Crown Victoria & Town Car 4.6L (2006–2011)
• Lincoln MKX 3.5L (2007–2010) and 3.7L (2011–2015)
• Mercury Grand Marquis 4.6L (2006–2011)

How does this module improve cooling system performance?

The control module adjusts fan motor speed across multiple levels so the radiator is cooled exactly as needed rather than running at full speed constantly. This targeted control reduces unnecessary electrical load and helps the engine reach and keep an optimal operating temperature more efficiently.

• Variable-speed control prevents overcooling and undercooling
• Rapid heat dissipation under high-load conditions
• Reduces alternator and battery stress for better fuel economy

What build and safety features does the AdvanEX module include?

This unit is engineered with robust electrical and mechanical details to match OE durability and connector placement. It includes protection features and high-current connections to resist common failure modes and to ensure long-term, reliable operation when mounted and wired correctly.

• High-current welded terminals for secure power delivery
• Integrated short-circuit protection to reduce electrical faults
• Mounting points and connectors mirror the original equipment layout

What should I check before installing this replacement module?

Confirming the original part number and connector style prevents fitment and compatibility issues. Also inspect the fan motor and wiring harness for damage—replacing only the module when upstream components are faulty can cause recurring problems.

• Compare OE numbers: 940002904, 6W1Z8B658AC, 6W1Z8B658AB, 902-209
• Confirm vehicle make, model, year and engine size
• Inspect fan motor and harness for wear before installation

Who this product is for: This AdvanEX Engine Cooling Fan Control Module is aimed at owners and mechanics who need a reliable, OE-form replacement for cooling fan control on compatible Ford, Lincoln and Mercury vehicles. It’s suitable for routine repairs, restoration projects, or when diagnosing intermittent fan operation—especially when the original module shows signs of electrical failure or intermittent speed control. AdvanEX provides a one-year after-sale support policy for manufacturing defects; buyers should double-check fitment and vehicle compatibility prior to purchase.
