Ford 3.5L EcoBoost fitment guide
Which Vehicles Use the 3.5L EcoBoost?
The Ford 3.5L EcoBoost was produced in both standard-output and high-output configurations across trucks, SUVs, vans and performance vehicles. Fitment varies by VIN, production year, turbocharger configuration and engine code, and the 2017-and-newer second-generation engine (port + direct injection, dual-chain timing) is not interchangeable with the 2010–2016 first generation. Always verify your VIN before ordering.

Why engines fail
Common 3.5L EcoBoost Engine Problems
When lubrication, cooling or timing maintenance slips, the failures below follow, and most of them send owners looking for a replacement engine.
Cam phaser rattle
Cold-start timing noise, cam correlation codes and drivability issues caused by worn phasers and timing components.
Timing chain stretch
High-mileage engines commonly develop timing chain slack, resulting in rough running and timing faults.
Turbocharger failure
Restricted oil supply damages turbo bearings and reduces boost pressure.
Carbon buildup
Direct injection creates intake valve deposits causing hesitation, misfires and reduced performance.
Internal water pump
Some transverse applications use an internal water pump capable of leaking coolant directly into the engine oil.
Bottom-end damage
Coolant contamination, overheating and poor lubrication eventually damage bearings and crankshaft components.

Frequently asked questions
3.5L Ford EcoBoost Engine Replacement FAQs
Is a remanufactured 3.5L EcoBoost better than a used engine?
Yes. A used twin-turbo V6 may already have chain wear, a tired turbo and bearing damage. A Fraser 3.5L is zero-mile and VIN-verified, with updated chains, guides, tensioners and phasers, verified oiling and new internals, all compression and leak-down tested.
Which vehicles use the Ford 3.5L EcoBoost?
F-150 (2011+), Raptor (2017+), Expedition, Navigator and Transit (2015+), Explorer Sport (2013–2019) and Platinum (2016–2019), Taurus SHO and Flex (2010–2019), Lincoln MKS (2010–2016) and MKT (2010–2019), plus Police Interceptor models.
What are the most common problems?
Cam phaser rattle, timing chain stretch, turbo failure, carbon buildup, internal water pump leaks on some transverse applications, and bottom-end damage.
Are all 3.5L EcoBoost engines identical?
No. There are standard and high-output versions, longitudinal and transverse layouts, and two generations. The 2017+ Gen 2 doesn't interchange with the 2010–2016 Gen 1. We verify your VIN first.
What warranty does Fraser provide?
Standard: 3 years / unlimited miles. Fraser Advantage™ (Options 2, 3 and 4): 5 years / unlimited miles plus 1 year free No-Fault. Labor paid at Mitchell or ALLDATA book time.
Can Fraser ship directly to my repair shop?
Yes. Shipping is free to any commercial address in the continental U.S.
Do I pay a core deposit upfront?
No. There's a $0 upfront core fee, and Fraser picks up your core after installation.
Is financing available?
Yes. Financing is available through Affirm and PayTomorrow, and we accept Visa, Mastercard, Discover and American Express.
