Which EcoBoost engine is best?
The 3. Liter EcoBoost Has Come A Long Way The D35 3. Liter EcoBoost features quite a few key upgrades over its predecessor, whose unreliability was highly-publicized, especially early on in its life. However, the second generation 3. EcoBoost is generally regarded as the most reliable Ford EcoBoost motor. All EcoBoost engines are equipped with a turbocharger, which helps to achieve the same horsepower as a conventional engine but with less displacement. So while the engine may be smaller, it is actually more powerful than a conventional internal combustion engine.
What is the weakness of the 2. EcoBoost?
Short answer: The most common problems with the Ford 2. Ecoboost engine are head gasket failures, carbon build-up, overheating, turbocharger issues, and spark plug & coil failures. Turbocharger Failure: The EcoBoost’s reliance on turbocharging for enhanced performance has led to issues with turbocharger reliability. Failures may include the turbocharger itself malfunctioning or related components such as wastegate problems that affect performance and fuel efficiency.The Ecoboost engine in early models is known for running hot. It had a nylon coolant pipe that often failed when exposed to high temperatures. This caused coolant to leak and the engine to overheat.
