3.5 EcoBoost Life Expectancy, Plus Tips to Make It Last Longer 

Most people know Ford as a global brand of cars, SUVs, trucks, and pickups. Not a lot are aware that they also manufacture some of the best engines in the market. Among others, one of the most popular is the EcoBoost, which the company claims can deliver the mileage that you need and the power that you want. 

In this article, we will talk about 3.5 EcoBoost life expectancy, which will give you a better picture of its reliability and longevity. We’ll also tackle some of the engine’s problems, and most importantly, what you can do to make it last longer. 

But first… 

What Is a 3.5 EcoBoost Engine?

Produced in 2009, the Ford EcoBoost is an award-winning turbo-charged and direct-injection petrol engine. Compared to a conventional engine, it is more powerful. Best of all, while it delivers outstanding performance, it is up to 20% more fuel-efficient, so you can enjoy the best of both worlds. 

The EcoBoost is a line-up of ground-breaking engines available in different variants, starting at 1.0L. However, this article focuses on the 3.5L variant. It is a V6 gasoline engine, which was first introduced as Twin Force. 

It was created to be a viable alternative to larger and power-hungry displacement V8 engines. Over the years, it became popular for being the engine that complements the F150, which is one of Ford’s best-sellers. 

What Is the 3.5 EcoBoost Life Expectancy?

A standard factory 3.5-liter EcoBoost engine has a life expectancy of up to 250,000 miles (402,000 kilometers). The engine is built tough to last long, so you can be confident that it offers peak performance for many years. Nonetheless, such is the case if you pay attention to proper care and maintenance. 

It is easy for the 3.5 EcoBoost to last longer than 250,000 with certain modifications, such as tune-ups and exhaust upgrades. Major customizations, such as large bumpers and suspension lifts may make the lifespan of the engine shorter as it needs to exert more effort for the car to run. 

Some owners note that their 3.5L EcoBoost engines reach a mileage of up to 300,000. This is unsurprising given the reliability of the engine. However, this is possible only under normal driving conditions and when you ensure regular maintenance, such as changing the oil when necessary. 

Most Common Problems with 3.5 EcoBoost

While most of the 3.5L Ford EcoBoost engines have a life expectancy of 250,000 miles, it can be shorter in some cases. This happens if the engine is prone to problems that limit its performance. 

These issues include: 

Timing Chain Wear

The timing chain connects the engine to the crankshaft and camshaft. It coordinates the movement of the valves. For optimal functionality, proper lubrication is important. Otherwise, it will not move smoothly.

Over time, it is subject to wear and tear. As a result, it elongates. Additionally, it disrupts the timing of the intake and exhaust valve. From increased emissions to engine efficiency, it brings a lot of problems. 

In a Ford EcoBoost, the pivot points in the chain link can bend backward. Often, this is a result of old age. To remedy the problem, remove and replace the chain. By using a new timing chain, you can restore the performance of the engine, and it will work like it is new. 

Carbon Buildup

As the fuel burns, carbon builds up in the engine, which affects performance. This build-up can shorten life expectancy. As a by-product of combustion, carbon build-up is normal, but you can avoid its detrimental effects if you know how to get rid of the deposits. Because EcoBoost has direct fuel injection, it is prone to carbon accumulation. 

One of the best ways to avoid carbon build-up in your Ford engine is the use of high-quality fuels. By doing this, the gasoline will be cleaner-burning, so you don’t have to worry about the build-up. 

Some people might resort to cleaning the fuel injector. However, take note that Ford does not recommend the latter. You can end up causing irreversible turbo damage if you use injectors.

Coolant Leaks 

A coolant is a must-have for the optimal performance of 3.5 EcoBoost. It is the lifeblood of the cooling system, preventing high temperatures. It picks up excess heat and brings it to the radiator. 

In many of the smaller Ford engines, a coolant leak is a common problem. It has even been the subject of a lawsuit that the company confronted for years. The issue has been addressed in the 3.5 EcoBoost, but that does not mean that it cannot happen. When a coolant leaks in the combustion chamber, a fire can start. 

When there is a coolant leak, one of the best solutions is to replace the old hose clamps. Also, check for any damage where the leak. Replacing the radiator and radiator hose can also be a quick fix. 

Ignition Issues 

Through the years, the Ford EcoBoost engine can suffer from an ignition failure. As a result, your car may not start, the lights will flicker, the engine will stall, or the key will not turn. The symptoms will depend on the extent of the problem. 

The ignition issues in EcoBoost are results of carbon deposits. It is a common problem that you will find in other turbo engines. Misfiring can happen as a result of an ignition problem. To add, it can be hard or impossible to start your car.

How to Extend the Lifespan of 3.5 EcoBoost

It is possible to extend a Ford EcoBoost engine’s life span and maximize its performance by doing the following: 

Change the Oil Regularly

Changing engine oil on time delivers plenty of benefits. For instance, it keeps the engine clean. It gets rid of dirt and particles that can form sludge and negatively impact engine performance over time. 

It also protects the other parts of your car, lessens emissions, and improves gas mileage. Overall, it is a great way to increase an engine’s life expectancy. 

Many owners of vehicles powered by Ford 3.5 EcoBoost change their oil between 3,000 to 5,000 miles. Some people change it at the same time as their tire rotation, making it easier to keep up with the schedule. 

Replace Filters when Necessary

Cars require different filters, which all impact the performance of the engine one way or another. One of the most important is an oil filter. It maintains a continuous flow while also getting rid of metallic and oxidized particles that can contaminate the oil. It reduces engine wear.

It is best to change the oil in a Ford 3.5 EcoBoost Engine every 6,000 to 10,000 miles. You do not need to do so every time you change the oil. When changing the oil filter, consider factors like size and capture efficiency, dirt-holding capacity, and pressure flow. 

Inspect the Timing Belt 

The timing belt is crucial for the effective operation of 3.5 EcoBoost. It synchronizes the movements of the engine’s internal components. Like the timing chain, it is prone to wear over time, and the failure to remedy the problem can result in costly repairs and engine inefficiency. 

We recommend changing the timing belt every 60,000 to 100,000 miles. Check the manual of your car for specific interval recommendations from the manufacturer. If you do not change the timing belt at the right time, you can end up having a bent or broken cylinder head and damaged valves. 

Prevent Overheating 

There are many reasons why the Ford 3.5 EcoBoost overheats. It happens when the cooling system fails to manage the heat in the engine’s compartment. Some of the culprits include blockages and leaks in the rubber hoses, water pumps, and gaskets. Problems in the radiator, coolants, and thermostats can also contribute to the problem. 

To prevent the EcoBoost engine from overheating, regularly inspect the radiator and coolant. See to it that they are working properly. It also helps to park your car in a shaded area and to tint your windows. Watch out for the temperature gauge. As soon as the engine overheats, pull over and implement the best fix possible. 

Practice Good Driving

Good driving habits will help extend the lifespan of Ford EcoBoost. Even if the engine has top-notch construction, it is useless if you are a reckless driver. By improving your driving behavior, your engine will last longer. 

Among others, one of the best things to do is to drive with lighter loads, which will put a lesser strain on the engine. Additionally, you should know how to shift gears properly. Being gentle during the break-in period also helps.
