How Ford's 3.5L V6 engine evolved from the TwinForce concept to become Ford's most potent V6 engine

Ford 's EcoBoost engine is one of the most significant engines in the automaker's fleet of power plants.

It has been a fundamental aspect of several models, notably the Ford F-150 and the hardcore hot-hatch Ford Focus RS .

The first -generation EcoBoost V6 engine had several issues, which included coolant leaks, a fault with its exhaust manifold, boost pressure leaks, boost-pressure leaks, wastegate canister failure, intercooler heat-soak issues, and timing chain elongation.

Ford employed this engine in several applications, ranging from the 2017 Ford Expedition Expedition to the 2018 Ford Expedition .

The third -generation 3.5L EcoBoost V6 has evolved into a capable power plant.

The engine was not without its faults, which included coolant leaks from the turbocharger system, exhaust manifold stud failures, excessive cam phaser wear, turbocharginger faults, excessive spark plug wear, and a plastic drain plug used in 20172018 engines that could cause engine failure.

Ford issued a recall for the 20242025 Ford F-150, Ford Expedition , and 2024 Lincoln Navigator because of a misaligned engine cup plug.
