Top 5 Ford 3.5 L EcoBoost Engine Problems: Let Fix Together

If you have the latest EcoBoost engine, you must be aware of the various Ford 3.5 L EcoBoost engine problems.

Here in the following article, we are going to discuss everything about this engine. 

With the constant increase in fuel prices worldwide, car manufacturers have been given the task of looking for effective solutions to keep consumption to a minimum.

Either with alternative propulsions or with new technologies for gasoline engines.

The latter is the case of the new Ford F-150 XLT V6 EcoBoost, a pickup almost 6 meters long that implements the EcoBoost engine technology that Ford already offers in several of its models.

This technology uses the implementation of forced induction and direct injection to reduce displacement without losing power and performance while improving fuel consumption.

Hence, EcoBoost technology comes with complete equipment and unexpected performance and becomes a great option for those looking for a pickup truck. 

Top 05 Ford 3.5 L EcoBoost Engine Problems with Solutions

The EcoBoost engine is one of the most recent innovations in the automotive industry.

All manufacturers compete for greater power and fuel economy while reducing emissions of harmful gases to the environment.

In the early 2010s, Ford began putting EcoBoost engines in everything from Fiesta and Focus models to F150s.

The EcoBoost engine is a combination of the turbocharger and direct fuel injection and is a great way to improve performance.

A “turbocharged” engine uses a turbine to force more air into the engine’s intake.

Released at the beginning of the decade, the EcoBoost engine is one of Ford’s greatest mechanical successes.

An engine that combines turbocharger and direct fuel injection to improve performance and reduce fuel consumption.

However, and without detracting from the virtues of this engine, the EcoBoost engine has presented several problems, as it happens with many new technologies.

1. Limited Operating Mode

In humid climates, the turbo can “inhale” enough moisture to put the engine in limited operating mode. However, Ford has issued a solution and technical service bulletins.

2. Software Issues

Various software updates for 2011 models related to vacuum, ignition, and shift points. Chain/timing tensioner wear due to past oil change interval.

Appearing as P0016 trouble code, Ford has issued a TSB.

3. Aerosol Cleaners Damage to Turbo Bearings

Ford has already advised to all the owners NOT to operate induction aerosol cleaner using the intake. It damages to moving parts, turbo bearings, and seals.

4. Timing Chain/Tensioner is Wearing

The timing chain/tensioner is wearing due to the past oil change interval. Appears with trouble code P0016. Ford has issued a technical service bulletin regarding the problem.

5. Failures in Engine Temperature Measurement

Some owners have reported failures in the measurement of the engine temperature since it takes this from the hose of the coolant water and not directly from the engine.

The Ford 3.5 L EcoBoost engine has been designed to provide a lean mixture that can deliver and cruising state, which is a rich mixture when the engine operates in loads like hill climbing or hard acceleration.

This new Ford 3.5 L EcoBoost engine uses various materials like iron and compact graphite aluminum for reduction of weight without forgoing its strength and valve timing and cam timing to increase fuel economy and power. 

Its direct injections require fuel to be within a high pressure, and Ford models’ piston crown and combustion chamber are specially designed to create a swirling effect on an intake stroke for better and more efficient combustion.

Best Ford 3.5 L EcoBoost Engine: Features & Specification

This latest 3.5 Liter EcoBoost engine is a twin-turbocharged engine from one of the world leaders Ford Motor.

It is utilized to power all types of cars from full-size to midsize, supercars, utility vehicles, pickup trucks, or all types of popular SUVs. 

The Ford F-150 XLT V6 EcoBoost is powered by a 3.5-liter V6 engine that develops 365 horsepower and 420 lb-ft of torque available from 2,500 RPM.

This allows it to have an acceleration that is more similar to that of a car than that of a pickup since the almost immediate action of the turbos gives it a response that when overtaking has no reproach, even on steep climbs.

If you are wondering, this EcoBoost engine model is perfect in the market. Let us tell you that it also has several issues, which we will be discussing today.

Ford 3.5 EcoBoost Specifications In-details

The New 10-Speed Automatic Transmission

Once the 2017 Ford F-150 combines the 3.5-liter V6 EcoBoost engine with the new 10-speed automatic transmission.

It offers an average consumption of 20 mpg (8.5 km / l) in the 4×4 version and 21 mpg (9 km / l). l) in the 4×2 variant.

EcoBoost 6-Cylinders

These EPA estimates show an improvement of 1 mpg (0.4 km / l) in the 4×2 and 2 mpg (0.8 km / l) in the 4×4, compared to the 2016 F-150 equipped with a six-speed automatic transmission and the previous generation 3.5-liter EcoBoost six-cylinder.

50 Pound-feet of Torque and 10 More HP

Regarding the latter, in addition to being more efficient, it offers more power, compared to its predecessor, it delivers 50 pound-feet of torque and 10 more hp.

In this way, the new generation twin-turbo V6 that achieves 375 hp and 470 pound-feet of torque outperforms all diesel and gasoline competitors, including V8 engines with almost twice the displacement.

Ideal for Hauling Heavy Loads and Trailers

For its part, the also new 10-speed automatic transmission – Ford’s first not to use cast iron components – improves the power and torque ranges, with shorter gearboxes.

These properties make it ideal for hauling heavy loads and trailers.

Ford 3.5 EcoBoost Life Expectancy

If we talk about the life expectancy of this new 3.5 L EcoBoost engine, it can easily give you up to 250,000 miles, which is similar to 402,000 km and more than that.

However, we must take care well of our engine with regular maintenance and no alterations.

The crankshaft, the pistons, the common-rail fuel supply system at 2,000 bar pressure, or the exhaust system have been redesigned.

It is now redesigned to withstand more severe temperature cycles and to withstand the prolonged stresses of use in a pickup – how to tow heavy loads on long slopes. 

Your Honeywell turbocharger blows at a maximum pressure of 1.5 bar.

It is heavier than the 3.5 EcoBoost engine and develops a maximum power of 250 HP at 3,250 RPM, with an interesting maximum torque of 600 Nm at 1,750 rpm.

Almost identical figures to those of the Land Rover Discovery.

Ford 3.5 EcoBoost Reliability: How Reliable are 3.5 EcoBoost Engines

Ford has done a great job to keep its Pickup trucks at the top.

The issue of efficiency is now very relevant. So much so that with the 3.5 L EcoBoost engine, it is possible to obtain consumption above 11 km / l without much problem.

But while it is true, it offers many improvements in terms of comfort, efficiency, and reliability. The work vehicle approach is not lost.

Even to the contrary, the towing and loading capabilities are the benchmark of the segment.

Maximum Power: 3.5 L EcoBoost engine develops a maximum power of 250 hp at 3,250 RPM, with an interesting maximum torque of 600 Nm at 1,750 rpm – almost identical figures to those of the Land Rover Discovery.

Direct injection and Two Low Inertia Turbos: The real novelty is in the new mechanical 3.5 liters EcoBoost engine of direct injection and two low inertia turbos that the firm calls Ecoboost.

And is that if getting US buyers to start migrating to smaller and more efficient engines in passenger cars is difficult. Raising that idea in the case of pickups seems simply crazy.

Of course, from a consumer point of view, this V6 EcoBoost is by far a better buy, as it is capable of hauling as much as the 6.2-liter V8, which is 11,300 pounds (5.125 kg). 

But it is offering better fuel economy than the 5.0-liter block. At the same time, the 365hp horsepower might not impress at first.

The 420 pounds of torque available at 90% from 1,700 to 5,000 turns allows it to do true wonders when it comes to dragging, loading, or just full throttle.

6-speed Automatic Transmission: All engines are coupled to a six-speed automatic transmission, and there is obviously the possibility of also incorporating a 4×4 system depending on the version.

Twin Turbochargers: Because the Ford 3.5-liter EcoBoost engine, with two parallel twin turbochargers, direct injection, and an after-charger, generates a power of 375 horsepower at 5,000 rpm.

Also, and an impressive torque of 637 Nm at 3,500 rpm, associated with a 10-speed automatic with trailer management, a manual option, progressive gears, and three driving modes.

In this case, the traction is 4 × 4 automatic (4WD).


Hope you are well aware of the Ford 3.5 L EcoBoost engine problems.

However, Ford has not declared consumption yet, but they aim to achieve an average of 7.8 l / 100 km according to the EPA cycle, more realistic than the NEDC. 

This new Ford 3.5L EcoBoost engine is in Ford F-150 Power Stroke 2018 with a diesel engine. And they play it. They are risking it because it has this powerful engine. 

A 3.5 L EcoBoost engine, a modified version of the V6 turbodiesel that Jaguar or Land Rover currently use, and which in the past even used some PSA Group vehicles.

Ford claims that the development of this engine began in 1999, but that before introducing it in the US.

Other hands, the engineers who developed the 6.7 V8 Power Stroke almost completely redesigned it. What’s more, they claim it shares little more than the block with these engines.
