Ford 1.6 EcoBoost Engine: Problems, Longevity, And Specs

By Nick Marchenko, PhD

The Ford 1.6 EcoBoost has all it takes to be an amazing versatile engine. It has power, efficiency, and reduced emissions, and yet there is a fatal flaw plaguing different EcoBoost engines. This defect in the way the engine block and cylinder head caused a lot of controversies, recalls, incidents and lawsuits.

However, even though there is a major issue with coolant leaks, we can still see plenty of car models using the Ford 1.6 EcoBoost engine. This does not mean that the issue can be ignored. Just that statistically, it is not very likely that your car will even have those detrimental side effects of the engine build. 

If you decide to buy a car that has this particular engine, be careful. With enough luck and some proper maintenance, the Ford 1.6 EcoBoost can be a reliable engine with great performance. But you should learn to identify the early signs of coolant leaks and know how to respond accordingly. 

Ford 1.6L EcoBoost Engine Specs & Horsepower

The Ford 1.6L EcoBoost is a compact 4-cylinder engine with a displacement of 1.6L. These engines run on petrol, but the direct fuel injection along with some other techniques, allow them to use fuel very sparingly. This helps with achieving an impressive 26/38 MPG. However, it comes at a price. The direct injection fuel systems are prone to clogging much faster. With this engine, you might need to clean up a little more often.

In terms of horsepower, the Ford 1.6L EcoBoost engine is also great, being able to produce 182 hp and 175 lb/ft torque. And all that is delivered with much better fuel efficiency than many similar or larger engines.

So, Ford 1.6 EcoBoost engine seems amazing if you only look at the specs. However, we mentioned some issues with defect blocks previously. To get a better idea of how this actually works (or rather doesn’t work properly) watch this engine strip-down video with expert opinion on the matter:

Possible Problems with Ford 1.6 EcoBoost Engine

The biggest issue with some Ford 1.6 EcoBoost engines is overheating. There were several instances of this engine model catching fire, involving serious injuries. It also caused many recalls for safety concerns. 

But overheating is not the only issue to be aware of, it is merely the most dangerous. It is best to check for official complaints in the NHTSA database, where they are structured and listed by model years. This will give you a better understanding of the possible issues with the car of your choice. Perhaps, the engine is not actually that problematic when put into perspective.

Overheating

This disturbing Ford 1.6 EcoBoost engine problem can be caused by a flaw in the block design and subsequent coolant leaks. Low coolant levels are often to blame for overheating in these vehicles, so keep an eye on the coolant level just in case.

To spot overheating in time, look for these symptoms: warning dashboard lights, steam or smoke from the engine compartment, and strange smell. If you know that your car has a problem with coolant leaks, stop to check the coolant level and look at the engine temperature gauge. But be careful with opening the hood, use protection for your hands and do not stand too close. Steam is very dangerous and it leaves deep burns.

To fix the issue, wait till the engine cools down and refill the coolant according to the manual and your coolant capacity. After that, check for leaks and go see a professional who can inspect the car for damage. Overheating can prompt corrosion and cracks on pistons, so do not skip this step.

Turbo failure

Another issue commonly reported by drivers is turbocharger failure. This Ford 1.6 EcoBoost engine problem can be identified by the common symptoms: loss of power, poor engine performance and gas mileage in particular. In severe cases, you can also notice smoke coming from a broken turbocharger. 

There is often no saving it, and the faulty turbo is simply replaced. But the biggest question is what may be causing this problem in the first place. Trace back to the root of the problem (clogged oil lines, low oil level or something else) and fix that issue before you continue on.

Coolant leaks

Unfortunately, many EcoBoost engines, together with Ford 1.6 EcoBoost, suffer from a flawed engine block design that allows coolant to leak into the cylinders, causing all sorts of problems starting with buildup and ending with overheating and misfires. 

The symptoms of this EcoBoost engine problem are white smoke from the exhaust, a quickly depleting coolant level, and a “Check Engine” light on the dashboard. There is actually no cure for this disease, you can either manage it or, if the warranty allows for it, replace it and hope for the best.

Oil leaks

The oil leaks can be just as dangerous and damaging to the engine as coolant leaks in terms of fire hazards. If the oil level drops below the safe level, it can cause costly or even irreparable harm to the engine. 

If you notice oil spots underneath the car, a low oil level ahead of time or even a burnt smell, this might indicate that you have an oil leak. Regular maintenance usually prevents any issues with oil leaks or deficiency. But if you find evidence that this is exactly what happened to your engine, find the source and replace or reseal the part.

Ford 1.6 EcoBoost Engine Life Expectancy

The Ford 1.6 EcoBoost engines can typically last for as many as 200,000 miles without much need for extra maintenance. This means that if you are lucky enough to pick a Ford with this engine that never experiences particularly bad coolant leaks, it can easily last for 10 years or so before you have to replace some worn-out parts or fix any problems.

These engines are quite reliable except for a certain defect lurking in the shadows. It is not very common, but it still exists and anyone can fall victim to this defect and the problems associated with it.

What Ford Models Use the 1.6 EcoBoost?

Thanks to the amazing mixture of power and efficiency, this compact engine became a very versatile part. It powers a range of different car models, from compact SUVs to subcompact cars. The careful balance of output and fuel efficiency makes it possible to replace bulkier and less eco-friendly engines with a smaller 1.6L steel heart able to produce just enough torque and hp to be a good match. The Ford 1.6 EcoBoost is a great reliable engine that can appeal to different driving styles and preferences. 

Here are some car models that currently come with the Ford 1.6 EcoBoost engine.

Is Ford 1.6 EcoBoost a Good Engine?

Yes, a Ford 1.6 EcoBoost is a good and reliable engine for a range of Ford vehicles. It manages to combine great performance and low fuel consumption thanks to its size and the technologies involved. The only big issue with these engines is the innate problem with how the engine blocks are cut out. This design oversight may or may not result in coolant leaks in the future, so the risk is there. But every day, millions of people go around their daily business in cars using the Ford 1.6 EcoBoost without any engine problems at all.

With a pinch of luck and proper maintenance, you can expect this engine to go for many miles and never remind you of itself. Just keep in mind that these issues can someday occur and be ready to act accordingly.

What is the difference between Ford 1.5L and 1.6L EcoBoost?

These two engines share a lot of features, but they differ in more than displacement. The Ford 1.6 EcoBoost can be considered more reliable than its smaller counterpart. It received less backlash from the coolant leak issue than the 1.5L EcoBoost and Ford models using it. It also is believed to last for a lot longer.
