Most commonly used in the Fiesta & Focus models, the 1.0 engine has been a highly regarded powerplant since its inception.
However, in addition to the normal faults that affect all Ecoboost engines, there are some potentially serious issues with the engine. This has had a negative influence on the company’s reputation, and the Ford 1.0 Ecoboost engine was affected by a number of recalls in 2018.

Ford found success in downsizing its engines by employing the EcoBoost with ultra-low friction, excellent efficiency, and a long-lasting design. They began to offer this engine as an option for many more vehicles over the years. The 1.0 EcoBoost is offered on the following models:

  • B-MAX
  • C-MAX
  • Kuga
  • Fiesta
  • Focus
  • Mondeo
  • Connect (Transit)
  • Courier (Transit)
  • Custom (Transit)

Common Problems

Since its introduction, the Ford 1.0L Ecoboost engine has undergone a substantial number of modifications. However, some of them were so outstanding that they received the IEPOTY award, while others received lower acclaim.

Ford claims that 44,682 Ford cars equipped with the three-cylinder turbocharged 1.0-litre engine and manufactured between October 2011 and October 2013 were equipped with a nylon coolant pipe between the engine and the coolant tank that had the potential to fail at high temperatures, according to the company.

96% of the automobiles were fixed as a result of a Field Service Action issued in March 2015 to replace the hoses on the vehicles. According to Ford, the issue was not treated as a safety recall by the Driver and Vehicle Standards Agency because a dash warning light should illuminate if the car begins to overheat, providing drivers with an early warning that there is a problem with the vehicle.

Carbon Buildup

One of the most common 1.0 Ecoboost engine problems is carbon build-up. Because the engine is equipped with a direct injection (DI) only fuel injection system, the fuel goes through the intake valve and leaves carbon residues.

Because the engine does not have a cleaning mechanism in the valve, this is an issue. Carbon eventually accumulates to the point that it obstructs the regular flow of petrol and causes damage to the valve.

A common symptom of this problem is that your vehicle experiences numerous misfires when idling and has a difficult time starting.

Another technique to discover the problem is to monitor your performance on a daily basis since, in addition to having a limited flow of petrol, the engine will have a reduced ability to function. This implies that your acceleration and MPG will be reduced.

This is not a major issue because it does not cause any long-term damage to your engine. You can drive your vehicle for many miles without encountering any difficulties.

As previously stated, there is no long-term remedy to this issue.

The only temporary option is to use the “Walnut Blast” approach, which costs around £500 and ensures that the valve remains clean for the following 75,000 miles of driving.

Cooling System

In particular, the engine’s coolant system proved to be a source of concern, and this was the primary cause for the engine’s recall in 2018.

The problem was caused by the use of nylon coolant tubing, which proved useless when the engine temperature reached a certain level. It resulted in a succession of issues, one of which being the engine fire.

When driving for long periods of time or at high speeds, these turbocharged engines can become extremely hot. When your vehicle hits a higher RPM, the coolant issue will begin to manifest itself in the form of hissing noises. After a time, you’ll see smoke coming from beneath your bonnet. If you do not come to a complete stop at this point, the engine can overheat and cause your vehicle to be undrivable.

Because the Ford 1.0L is such a little engine, there is no possibility to fit a bigger pipe with high-temperature endurance at that location. The only fix is a replacement component which should give you many more years of loyal service.

Low Fuel Pressure Issues

The Ford 1.0L is well-known for having a high MPG engine, however, owners have reported issues with the low-pressure fuel pump (LPFP)

In order to achieve high MPG, the engine must operate at extremely high temperatures, placing a great deal of strain on the fuel pumps, which in turn reduces their performance and the overall longevity of the component.

You may notice knocking sounds under the bonnet. Following some time, your car’s engine will shut down automatically, resulting in a stuttering performance. You’ll also experience a high number of misfires throughout the ignition process.

The solution to this problem is straightforward. It may be completed for free if you are still covered by your manufacturer’s warranty if your vehicle is under 3 years old. Simply take your vehicle to your local garage or dealership and have the cam bucket replaced. This will increase your LPFP and allow you to fully utilize the engine’s full capabilities.
