Used Ford 3.5L Duratec V6 for Sale — VIN-Verified.
VIN-verified, road-tested used gas engines for cars, trucks, and SUVs — matched to your exact vehicle and backed by a real warranty. 0% restocking, ever.
Used & remanufactured Ford 3.5L Duratec V6 — VIN-verified, tested, and shipped nationwide from our Pasadena, TX facility. Fits Ford Explorer, Taurus, Flex, Edge; Ford F-150 (base 3.5 NA).
This is Ford's naturally aspirated 3.5L Duratec/Cyclone V6 (not the twin-turbo EcoBoost) used in Explorer, Taurus, Flex and base F-150, so we VIN-verify carefully to avoid confusing it with the EcoBoost since the two share a displacement but nothing else. Water-pump wear (internal on some applications) is a known concern, which we inspect, and every engine gets a compression and leak-down test before shipping from Pasadena. Ultra Auto Parts TX is Houston's drivetrain specialist, supplying quality used and remanufactured gas engines out of our Pasadena, TX facility at 5041 Spencer Hwy, Ste 101. Every engine we sell is sourced, inspected, and VIN-verified against your specific vehicle before it ships — no random salvage guesswork. As a used-engine dealer serving the greater Houston area, we test compression, run leak-down and bore-scope checks, and confirm mileage so you know exactly what you're buying. Whether you drive a Chevy Silverado, Ford F-150, Toyota Camry, Honda Accord, or a Nissan, Dodge, GMC, or Jeep, our bilingual English/Spanish team helps you find the right long block or complete drop-in engine. Send us your VIN and we'll match the correct engine family, displacement, and options so it bolts in right the first time.
Known issues we check on the Ford 3.5L Duratec V6
This is Ford's naturally aspirated 3.5L Duratec/Cyclone V6, not the twin-turbo EcoBoost, so we VIN-verify carefully since the two share a displacement but nothing else. The known weak point is the internal, timing-chain-driven water pump on many applications, which can leak coolant into the engine when it fails, so we inspect that closely along with timing-chain and cam-phaser condition. Every engine is VIN-matched to your Explorer, Taurus, Flex, Edge, or base F-150 and compression- and leak-down-tested in Pasadena before we quote.
Used vs. remanufactured Ford 3.5L Duratec V6 — which to buy
A tested used 3.5L Duratec is a solid value when the water pump and timing components check out, and ours are inspected for exactly those points. Remanufactured makes sense on high-mileage units, especially since the internal water pump is labor-intensive and worth having refreshed with a longer warranty. We carry both and match to your vehicle and budget. Send your VIN and we will give you honest guidance so you get the naturally aspirated engine, not an EcoBoost by mistake.
Why buy a quality used engines?
A quality used engine is the smart middle ground between an expensive brand-new crate engine and a risky unknown. You get genuine OEM components engineered for your exact platform — correct block, heads, and sensor locations — at a fraction of new-engine cost. Low-mileage salvage engines pulled from wrecked-but-running vehicles often have plenty of service life left, and because they're OEM, fitment and reliability beat generic aftermarket overhauls.
Common signs you need a replacement
Most drivers come to us after a blown head gasket, a spun rod bearing (rod knock), cracked block from overheating, a thrown timing chain, or oil-starvation damage. High-mileage engines burning oil or losing compression are common triggers too. When the repair bill approaches the engine's value, a VIN-matched used replacement is usually the faster, more affordable path back on the road.

Fitment Flags We Check
- LS 5.3 vs 5.7 (LM7 vs LS1) — different displacement, blocks and accessories don't freely interchange
- VVT vs non-VVT variants — cam phaser and controller differences change fitment and wiring
- Flex-fuel (E85) vs standard gas — different injectors, sensors, and calibration
- 8th digit of the VIN identifies the engine code — always confirm it matches
- Truck vs car/SUV accessory brackets, oil pan, and intake can differ on the same engine family
- Early vs late LS (24x vs 58x reluctor) affects harness and PCM compatibility
