Ford 2.0L EcoBoost GTDI Engine: Specs, Problems, and Reliability. The Ford’s 2.0 EcoBoost is a 2.0-liter four-cylinder gasoline turbocharged engine with direct fuel injection. It is also called sometimes as a Ford 2.0 GTDI engine (Gasoline Turbocharged Direct Injection). Ford Motor Co. introduced the first 2.0 L EcoBoost in 2010. The engine currently is provided in many Ford’s vehicles globally, including Fusion, Focus ST, Edge, Escape, Explorer, Taurus in North America, the Falcon in Australia, the Mondeo, and S-Max in the European market. The EcoBoost family also features a bigger 4-cylinder engine – 2.3 L EcoBoost.
The 2.0 L EcoBoost includes two generations already. The 2.0 EcoBoost GTDI engine was significantly redeveloped in 2015. The new version (the twin-scroll 2.0 EcoBoost) shares almost no parts with the predecessor, but it is still produced by the same name while the old engine is gradually replaced in all vehicles. Let’s take a closer look at each of them.
The First Generation 2.0 L EcoBoost Engine
The engine has a high-pressure die-cast aluminum “Open-Deck” style cylinder block with high strength steel sleeves molded in the block material. The engine block is equipped with a cast-iron crankshaft with eight counterweights, five main bearings (diameter is 52 mm), and a damped front pulley. There are also forged steel “I-beam” connecting rods and aluminum pistons with low friction coatings on the piston skirt. The engine block has pistons cooling oil jets. On top of the block, there is a cast aluminum cylinder head with double overhead camshafts.
Depend upon the market and application, the 2.0 l GTDI engine has a water-cooled exhaust manifold integrated into the cylinder head or a conventional head with a separate exhaust manifold (it is made as one unit with a turbocharger). There are four valves per cylinders – two exhaust and two intake valves (16 valves total). The engine has a variable timing for intake and exhaust valves (Ford’s Twin independent Variable Cam Timing or Ti-VCT). The intake and exhaust camshafts are driven by a single-row timing chain.
The 2.0 l EcoBoost features the high-pressure petrol direct injection fuel system. Each cylinder has a 7-hole injector that injects fuel directly into the combustion chamber. The high-pressure fuel pump is mounted atop the cylinder head and driven by a four-sided camshaft lobe. The fuel pressure is between 65 and 2150 psi, depending on demand. Another key component that allowed the engine to provide such a good power output and fuel efficiency is a turbocharger. The cooled exhaust gases spin the low-inertia Borg Warner K03 turbocharger, which compresses the intake air and sends it into a plastic intake manifold through an air-to-air intercooler mounted before a vehicle.
The ignition is electronically controlled, and each ignition system has an individual ignition coil. The engine operation is controlled by the Bosch MED17 ECU. To stop the detonation, the engine was equipped with individual knock control. The throttle body is also digitally controlled. The throttle valve is actuated relying on a signal of the gas-pedal position sensor, engine temperature, and other engine control and vehicle systems like ESP and etc.

The Second Generation Twin-Scroll 2.0 EcoBoost Engine
The new twin-scroll 2.0-liter EcoBoost engine debuted in the 2015 Ford Edge and presently is delivered in Ford Everest, Ford Tourneo, Ford Escape, and Ford Fusion. The main target in front of engineers was more pleasurable and responsive in drive engine, with better performance and fuel efficiency in Ford’s all-wheel-drive applications than the current 2.0 EcoBoost version.
The new 2.0 has a new aluminum cylinder block and redesigned aluminum cylinder head with an integrated exhaust manifold optimized for the Borg-Warner twin-scroll turbocharger. The exhaust gases from cylinders 2 and 3, and 1 and 4, go separately into each scroll of the turbocharger reducing the moment needed to reach full boost. The new turbocharger also has an active wastegate, which allows accurately manage boost and torque levels. Moreover, the new 2.0 l EcoBoost engine features revised fuel injectors with more precise fuel delivery, forged steel crankshaft, new pistons, higher squeezing ratio (10.0:1 vs 9.3:1), and an active oil control system. The twin-scroll 2.0 engine is also lighter by about 10 pounds than the predecessor.
2.0 EcoBoost GTDI Engine Problems and Reliability
Ford’s 2.0 EcoBoost GTDI engine does not have huge problems, but still, some car owners faced some troubles throughout the years of production.
The engine with a separate exhaust manifold is the leader around consumer messages about problems with 2.0 l EcoBoost engines. The main subject is an exhaust manifold itself. The stainless steel exhaust manifold leans to cracking and further destruction at relatively low mileage (50-60k miles). The main disadvantage is that the exhaust manifold is one unit with a turbocharger, which makes the replacement is quite expensive.
Failure of the turbocharger control valve is a common problem. The engine loses power and the message “check engine” shows up on the dashboard. When turning off the ignition and then turning it on, the error message disappears. The control valve replacement is required to fix this problem.
In the fuel system, the main source of trouble is a low-pressure fuel pump. The fuel filter in the tank is simply clogged and does not allow the pump to deliver the required pressure and enough fuel for a correct high-pressure pump operation. A car with that issue has a bad acceleration or slow max speed. Failure of high and low circuit fuel pressure sensors has similar symptoms but happens very rarely.
You need to also know that direct injection engines are prone to carbon buildup on the intake valves backside and on walls of the intake ports. To keep the same output efficiency and fuel consumption, a periodical carbon/soot cleaning method is necessary for Ford’s EcoBoost engines.
