It is the first EcoBoost engine to include twin independent variable cam timing (Ti-VCT), with advertised 10–20% better fuel economy while maintaining the performance of 3.0 L V6s. [ 40 ] [ 41 ] This engine is derived from the 2.0 L Mazda L engine block used by Ford in the North American Focus MK3, but equipped with unique heads, fuel ...
Due to packaging differences in transverse (FWD) applications, the water pump is relocated to the valley behind the timing cover and is driven by the timing chain. The 3.5 L engine will fit into any engine bay the smaller Duratec 3.0 L will, and replaced it in some applications (notably the Ford Taurus) in the 2008 model year.
Unlike the SHO V6, the SHO V8's valvetrain was an "interference" design, one that is shared by many engines built today, meaning that the piston will collide with the valves if the camshaft or timing chain fails. Due to some cam sprocket failures, the engine acquired a reputation for potentially catastrophic failure.
Water pumps on 2008-2019 Taurus and 2013-2019 Police Interceptor models equipped with the 3.5L Ford Cyclone V6, 3.5L EcoBoost V6, and 3.7L V6 have a tendency to fail, potentially ruining the engine. The water pumps on these engines are internally mounted and driven by the timing chain.
It uses a jackshaft in place of a camshaft to drive a timing chain to each cylinder head. Three timing chains are used, one from the crank to the jackshaft, one in the front of the engine to drive the cam for the left bank, and one on the back of the engine to drive the cam for the right bank. In addition, the 4WD Ranger/Explorer with the SOHC ...
Water pumps on 2011 through 2019 Ford Explorer and 2013 through 2019 Ford Police Interceptor Utility equipped with the 3.5 L V6, 3.5 L EcoBoost V6, and 3.7 L V6 have a tendency to fail and potentially ruin the engine when they do. The water pumps on these engines are internally mounted and driven by the timing chain.
The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres.Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec ...
A racing version of this engine exists and is used on mini prototypes like the Juno SS3 V6. It is a 3.0 L (2,967 cc) naturally aspirated non variable timing engines producing between 350 and 400 hp (261 and 298 kW) with a redline of around 8700 rpm. The engine has a 40-hour racing life span before it needs to be rebuilt with rings and bearings ...
