EGR Valve for 2004-2010 Ford Explorer Sport Trac & Mercury Mountaineer 4.0L V6

Exhaust Gas Recirculation (EGR) Valve for Ford Explorer / Sport Trac and Mercury Mountaineer

Replacement EGR valve for the exact source-listed Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer 4.0L V6 model-year applications below.

Critical fitment warning: Fitment is model-, year-, engine-, and emissions-system-specific. The source identifies 4.0L V6 fitment but does not provide the engine code, federal versus California emissions certification, production-date breaks, connector pin count, valve calibration, flange shape, port dimensions, coolant connections, gasket configuration, or formal OE reference numbers. Confirm the VIN, exact 4.0L V6 engine code, emissions label, production date, original EGR valve number, electrical connector, mounting flange, ports, coolant connections where applicable, and gasket pattern before ordering.

Ford Compatibility

• 2004–2010 Ford Explorer — 4.0L V6
• 2004–2005 Ford Explorer Sport Trac — 4.0L V6
• 2007–2010 Ford Explorer Sport Trac — 4.0L V6

Mercury Compatibility

• 2004–2010 Mercury Mountaineer — 4.0L V6

Important exclusion: 2006 Ford Explorer Sport Trac is not listed by the source. Do not extend the two confirmed Sport Trac ranges across that missing year.

Not confirmed: V8 applications, other engine sizes, unlisted years or models, or vehicles whose emissions system, original valve, connector, flange, ports, or calibration differ.

Included Component

• 1 EGR valve

The source does not confirm an EGR gasket, O-ring, mounting bolts, coolant seals, hoses, clamps, wiring, connector repair kit, EGR pipe, cooler, or additional installation hardware. Verify the product images and received package before installation.

Specifications Requiring Verification

• Exact 4.0L V6 engine code
• Federal or California emissions configuration
• Production date and market specification
• Electrical connector shape and pin count
• Mounting-hole pattern and flange profile
• Exhaust and intake port shape
• Coolant-port configuration, if applicable
• Original valve calibration and reference

Reference Verification

No formal Ford or Mercury OE or interchange reference numbers are provided in the source description. Do not use the listing SKU alone as proof of interchange. Match the VIN, emissions label, original valve markings, connector, flange, and ports.

Installation Notes

EGR-system diagnosis and replacement should be performed by a qualified technician. EGR-related fault codes can also be caused by restricted passages, wiring faults, connector damage, vacuum or intake leaks, sensor issues, cooling-system problems, or engine-control faults. Diagnose the complete system before replacing the valve.

Allow the engine and exhaust system to cool. Disconnect the battery when required by the vehicle-specific service procedure. Inspect and clean mating surfaces and EGR passages without allowing debris to enter the intake or exhaust system. Use the correct new gasket or seals where required and follow the specified bolt sequence and torque values. Refill and bleed coolant if any coolant circuit is opened.

After installation, inspect for exhaust, vacuum, and coolant leaks. Clear applicable diagnostic codes, complete any required idle or EGR relearn procedure, and verify commanded versus actual EGR operation with suitable diagnostic equipment. Confirm stable idle and normal operation before road use.

Frequently Asked Questions

Does this fit a 2006 Explorer Sport Trac?
Not based on the supplied fitment. The source lists 2004–2005 and 2007–2010 Sport Trac, leaving 2006 excluded.

Does this fit V8 models?
No V8 application is confirmed. The source-listed engine is 4.0L V6.

Is a gasket included?
Gasket and seal inclusion are not confirmed.

Will replacing the valve clear an EGR fault code?
Not necessarily. Restricted passages, wiring, sensors, leaks, or control-system faults can produce similar codes and should be diagnosed first.
