3.5L Engine Common Problems
Just as nothing is flawless, the same goes for this engine. Still not believe us? Here are the two main issues to prove our point.
Ignition System Issues
Ignition coils usually last for 140,000 miles. However, it wears down much faster in 3.5L Ecoboost. As a result, you experience misfires and stuttering issues.
Misfires in the plugs and coils may lead to ignition system issues. Now comes the question of how to avoid it?
It’s simple; look for carbon tracks and replace all the plugs with new ones. You can also pull the ignition coil and swap it with the perfect ones.
3.5L Timing Chain Issues
The ratio of timing chain issues is slightly higher in F-150 model engines.
The 3.5L Ecoboost is a turbocharged technology that makes the engine oil more susceptible to stress issues.
When you delay changing oil frequently, the oil filter system gets worn out.
As a result, the chain starts stretching and eventually fails to perform its functions.
How can you determine that something is going on with the timing chain?
Now to answer this question, you should look if your car starts with a rattle. Also, keep checking engine lights.
Factors to Consider Between 2.7 Ecoboost vs 3.5 Ecoboost
Now that you have a precise concept of what they generally offer. Opt for 2.7L Ecoboost if you want to run daily errands with fuel economy.
However, go for 3.5L Ecoboost if you are after a remarkable performance.
Are you still contemplating your options? Why not make it easier for you by exploring the article below!
Let’s go through the differences between 2.7 Ecoboost vs 3.5 Ecoboost specs.
Before we compare the horsepower of each engine, let us discuss how horsepower differs from torque?
Are not they the same thing? If not, then what makes one different from the other?
In simple terms, horsepower highlights how timely your engine delivers its work. In addition, torque defines how much does your engine work.
The 3.5L delivers 375 hp while 2.7L offers 325 hp so, if you prefer more power- your right choice is the 3.5 Ecoboost.
Have you any idea what torque generally means? If No, we can make it easier for you.
Torque is simply a circulatory force. You can say; it is the strength of the engine. More torque offers more acceleration.
The 2021 V6 2.7L engine offers standard torque of 400 lb-ft. It is a remarkable value in itself.
Moreover 3.5L has greater torque values and hence greater strength.
In short, we recommend going for the 3.5| Ecoboost if you are after more torque-oriented engines.
As we said before, both are gas-operated engines. However, they differ in terms of fuel mileage. Let us take a quick look at the 2.7L Ecoboost vs 3.5L Ecoboost fuel mileage.
Do you know why Ecoboost engines have direct-injection fuel systems? Because these systems help enhance fuel economy and better mileage.
However, 3.5L engines are more powerful and offer more hp, torque, towing capacity and, payload capacity.
Also, it is the latest turbocharged technology that makes it less economical than the 2.7L.
Aren’t you familiar with the term displacement like us? Are you feeling confused if it is somehow related to time?
You need not sweat it up. Let’s look through the article with us.
Displacement refers to the change in position following time.
So yeah, both are directly related to each other. Now that you know displacement. What engine should you choose?
As the name suggests- 2.7L Ecoboost covers 2,694 ccs. Whereas; 3.5L tops the chart again.
Let’s learn about towing capacity before comparing the Ford 2.7 Ecoboost vs 3.5 Ecoboost.
Towing capacity refers to tow the weight of the truck and the cargo on it.
The Ford provides one of the most versatile trucks for its remarkable towing capacity. However, the 3.5 engine offers 13,800 that is more than the 2.7 engine ones.
You need not worry anymore as the 3.5L Ecoboost once again won the battle for providing maximum facilities to drivers like us.
Before jumping to comparison, you should be clear that towing capacity and payload capacity are two separate terms.
Can you differentiate between pulling and carrying? If yes, consider the same instance to separate towing and payload capacity.
It is much easier to pull an object rather than to carry it. The same concept goes for a truck.
The load a truck can pull- towing capacity. Whereas the weight a truck can carry- payload capacity. Is not it easier to remember now?
The 3.5 engine offers more payload capacity than the 2.7 one. We recommend you root for the 3.5| Ecoboost engine for better results.
An engine is like the heart of any system that requires maintenance to enhance its life span. Maintenance upgrades the engine mileage and reliability.
Before comparing the 2.7 Ecoboost vs 3.5 Ecoboost reliability, let’s define reliability.
Reliability is the quality of an engine that shows its performing consistency.
Reliability is a much-debated topic. We can not pinpoint if one engine is reliable over the other.
However, we can increase the engine reliability with proper maintenance.
Now comes the question of how to maintain it? Maintenance involves replacing the fuel filter and changing engine oil frequently.
The 3.5 engines cost more than the 2.7 ones. The base price of a 2.7L engine is about $45,500.
Also, a 3.5L engine costs $1,400 more than it. Let’s cut it short and learn why!
It’s not a secret; the 3.5 Ecoboost delivers more hp and torque. Furthermore, you can tow heavy loads with more ease.
Overall low cost and fuel economy make the 2.7L engine an all-around better pickup truck in this comparison.
2.7L Ecoboost vs 3.5L Ecoboost – Which One to Choose?
