What engines are used in the Ford Explorer?

In brief, the Ford Explorer lineup in the United States currently relies on three powertrains: a 2.3‑liter EcoBoost turbocharged inline‑4, a 3.0‑liter EcoBoost V6 for higher trims and performance variants, and a hybrid 3.3‑liter V6 paired with electric motors. This article breaks down where each engine appears and what they deliver.

Gasoline powertrains

The Explorer’s gasoline-only options balance efficiency and performance across the model range. The following engines are currently offered in most trims.

Engine options

2.3-liter EcoBoost inline-4 turbo — 300 horsepower and 310 lb-ft of torque; widely available across most trims and paired with a 10‑speed automatic transmission.

3.0-liter EcoBoost V6 — about 400 horsepower and 415 lb-ft of torque; primarily found on higher trims and the Explorer ST, delivering strong acceleration and towing capability.

Conclusion: The gasoline lineup provides a base of efficient performance with the 2.3L EcoBoost and a high-performance option on the 3.0L EcoBoost for buyers seeking extra power.

Hybrid powertrain

The Explorer also offers a full hybrid option that combines the 3.3-liter V6 with electric propulsion. This setup is not a plug-in hybrid; the battery is charged through the engine and braking during normal driving.

Hybrid specifics

3.3-liter Hybrid V6 — combined system output around 318 horsepower and 322 lb-ft of torque; aimed at improving real-world fuel economy while maintaining usable everyday performance.

Conclusion: The hybrid powertrain appeals to buyers prioritizing efficiency without sacrificing practical power for daily driving or light-duty towing.

Summary

The Ford Explorer’s current engine lineup focuses on three configurations: a standard 2.3L EcoBoost for most models, a 3.0L EcoBoost V6 for higher trims and the ST variant, and a non-plug-in hybrid pairing of a 3.3L V6 with electric motors. This mix gives buyers a choice between balance, performance, and efficiency depending on their needs.

What Ford engine to stay away from?

Ford engines to avoid include the 6.0L and 6.4L Power Stroke diesels, which had numerous issues like EGR cooler failures and injector problems, and the 5.4L Triton V8 known for spark plug and timing chain problems. Other engines to be cautious of are the 3.8L V6 due to head gasket failures and certain EcoBoost engines, especially early 1.0L and 1.6L models, which have faced issues like premature timing belt wear and overheating.

Engines with high failure rates

6.0L and 6.4L Power Stroke diesel engines: These engines (2003-2007 and 2008-2010, respectively) are notorious for expensive problems, including head gasket failures, injector issues, and turbocharger failures.
5.4L Triton V8: This engine (1997-2010) is infamous for spark plugs breaking during removal and cam phaser/timing chain issues.
3.8L SX V6: From 1982 to 2008, this engine had issues with weak head bolts causing head gasket failures, and early versions were prone to coolant leaks.

Problematic EcoBoost engines

1.0L EcoBoost (early versions): Early models used a rubber timing belt in hot engine oil, which could degrade and clog the oil pickup, leading to oil starvation and engine damage.
1.6L EcoBoost: This engine has been associated with overheating and coolant leaks.
3.5L EcoBoost: Problems can include carbon buildup, premature timing chain wear, and water pump failures.
2.7L EcoBoost: Early models (around 2016-2017) experienced issues with defective valve guides, excessive oil consumption, and leaking plastic oil pans.

What year Explorer to stay away from?

You should stay away from the 2002–2006 Ford Explorer models due to frequent and expensive transmission problems, engine issues, and suspension wear. Other years to avoid include the 2016 and 2020 models, which have reported issues with electrical systems, faulty parts, and transmission problems.
Model years to avoid

2002–2006: The third generation is widely considered the least reliable due to significant transmission failures, engine problems (like timing chain issues), and premature suspension wear. The 2002 model year has the highest number of overall complaints, primarily for its transmission.
2016: This model year has been criticized for issues like faulty fuel tanks and suspension components, as well as poor rearward visibility and lack of interior storage.
2020: As the first year of the current design, the 2020 model is noted for a high number of recalls, particularly involving transmission problems that can cause stalling and power loss.

Other years with potential issues

2011–2019: This generation has drawn complaints about electrical system problems.
Early 2021 models: Some 2021 models built in late 2020 and early 2021 had issues, though later models made in late 2021 are generally considered more reliable.
