2018 Ford Expedition 3.5L EcoBoost Engine Replacement Cost

A 2018 Ford Expedition 3.5L EcoBoost engine replacement usually means a remanufactured twin-turbo V6 — remanufactured pricing is quoted per unit, so call for the current price on your VIN. The 3.5L EcoBoost is strong, but cam phaser rattle is the symptom that decides the repair.

Cam phaser rattle A rattling noise on cold start that lasts a few seconds is the classic 3.5L EcoBoost cam phaser symptom. The phasers wear and lose oil pressure control; the rattle gets longer and louder over time, and eventually sets timing fault codes. A phaser job is a component repair — but on a high-mileage engine it is often the first sign the timing system is due for a full replacement.

Timing chain stretch A rattle that persists after warm-up, timing fault codes, or a check-engine light for cam/crank correlation usually means the timing chain has stretched. A stretched chain affects performance and, if it jumps, causes catastrophic valve damage.

Turbocharger wear A whine, loss of boost, or excessive oil consumption can point to turbo wear at high mileage. A turbo is a component repair — diagnose it before assuming the engine is done.

For the part itself, a remanufactured 3.5L EcoBoost for the 2018 Expedition is quoted per unit — call for the current price on your VIN. Pricing moves with trim, 2WD versus 4WD, mileage, and availability. Add installation labor, freight, and a refundable core charge on remanufactured units. A remanufactured unit arrives with the stronger warranty: up to 5 years with unlimited miles, parts and labor.

A used 3.5L EcoBoost is the lower-cost path and a first-class option here: a pull from a donor vehicle, inspected and documented with mileage, that gets a solid vehicle running again without a large outlay. It carries up to 5 years or 50,000 miles of parts-only coverage. A remanufactured 3.5L EcoBoost is fully disassembled, inspected, and rebuilt to specification with new wear components and tested before it ships. It costs more, but it arrives with the stronger warranty — up to 5 years with unlimited miles, parts and labor — and it is the smarter long-term choice if you plan to keep the vehicle for years. Either way, confirm the VIN, the engine code, and 2WD versus 4WD before you order, and have a licensed shop do the install.

We back every engine we sell, and the two warranties are different in a way that matters when you choose. A remanufactured engine carries up to 5 years of coverage with unlimited miles (gasoline, non-commercial, 2001 and newer), parts and labor included, with labor reimbursed at $50 per hour per the Mitchell labor guide after an approved claim. A used engine carries up to 5 years or 50,000 miles, parts only, with no labor reimbursement. Both require installation by a Licensed Automotive Repair Facility, and used units must be installed within 14 business days of delivery with the heat tabs intact. Remanufactured units also carry a refundable core charge, returned when your old engine comes back to us.

Replacement is the right move when the failure is isolated to the engine and the rest of the vehicle is worth saving — solid body and frame, good tires, no major suspension or electrical issues. A quality used or remanufactured engine can extend the life of an otherwise good vehicle by years at a fraction of the cost of a replacement vehicle. Get an honest assessment first: if the vehicle also needs major work elsewhere, or the repair cost approaches the vehicle's value, the math changes. Proper diagnosis from a trusted mechanic is the essential first step — don't replace what doesn't need replacing, but don't pour repair money into an engine that is already mechanically compromised.
