VERDICT · STRONG TOWING CHOICE, VERIFY GENERATION

Ford F-150 3.5L EcoBoost
is it a safe used buy?

The twin-turbo V6 alternative to the 5.0L Coyote V8 on this F-150 generation — genuinely strong towing torque, with the same generation-specific water pump and intercooler checklist covered on this engine's own dedicated page.

How the engine fits this car

This generation's aluminium body keeps weight down, and this twin-turbo V6 delivers genuinely strong low-end torque for towing — the same engine covered in detail on the related Explorer page, here offered as the high-output alternative to the naturally aspirated 5.0L V8 on this truck.

This generation falls mostly within the engine's second-generation production window (from roughly 2017), which carries meaningfully lower risk than the first-generation examples covered in the engine page's early-production checklist — worth confirming the exact build year.

Ford F-150-specific pros and cons

This is about the car itself — for engine-specific failure points, see the dedicated engine page below.

WHAT HOLDS UP WELL

  • Genuinely strong low-end torque, class-competitive towing capacity for the segment
  • Second-generation (2017+) engines meaningfully improved on the first-generation's documented concerns
  • Twin-turbo layout delivers power with less weight over the front axle than the related V8
  • Strong real-world data given how widely this engine is used across Ford's lineup

WHAT TO WATCH

  • Early production (2015–2016) examples carry the water pump and intercooler considerations detailed on the engine page
  • Carbon buildup on intake valves, the usual direct-injection trade-off
  • Fuel economy advantage over the 5.0L V8 is real but modest in real-world towing use
  • Turbocharger and related component wear is a consideration worth monitoring as these engines age

Pre-purchase checklist for this generation

Check the exact production year and generation — second-generation engines carry meaningfully lower risk than early first-generation examples.

Ask about water pump history on first-generation (2015–2016) examples specifically, per the engine page's guidance.

If the truck has been used for towing, ask about typical load and frequency, and inspect transmission behaviour under load during the test drive.
