6.7 Powerstroke Problems

Written By: ProSource Diesel

Ford started using the 6.7 Powerstroke diesel engine in 2011—a significant technological boost from the 6.4L engine—and the truck manufacturer is still using them in their 2022 models. These 800-pound engines are brawny—and people who buy vehicles with this type of diesel engine are usually thrilled by their truck’s power as well as its smooth and quiet ride.

(If, by the way, you see the engine referred to as a “Power Stroke” or a “Powerstroke,” we’re still talking about the same Ford diesel engine.)

The good news: it’s a relatively low percentage of owners who experience problems with this engine with many of the issues occurring in Gen 1 models when Ford was still improving upon this powerful engine technology. That said, if you’re the one having a problem, you need a fast solution, and this post can help.

These engines are divided into three generations and, when buying replacement diesel truck parts, it’s important to select the ones for that year’s model:

Now here’s more information about the problems people have experienced with their Ford 6.7 diesel engines.

Radiator Leaks

The earliest models often developed these leaks, some minor and others more severe. Ford pickup trucks in the model year of 2012 and beyond have experienced fewer of these issues.

Glow Plug Problems

Again, when this problem arose, it’s typically been with the earliest models, such as the 2011 trucks. When tips separated from the glow plug, problems could be huge. In later years, glow plug problems were often part of an exhaust valve failure.

Oil Leaks

Gen 1 models sprung leaks from the vacuum pump gasket, usually because of loose bolts. Tightening them up would help, but you’d probably also need a gasket replacement.

NOx Sensor Problems

These failures happened frequently with 2011 model years to the point where Ford created the Custom Satisfaction Program 12B33 that would last through the end of April 2013. Ford owners who experienced this issue could have NOx sensors checked and replaced. They also received an SCR system upgrade for emission control.

Turbocharger Challenges

Ceramic ball bearings, especially in the 2011 and 2012 model years, led to turbo failures that were expensive to address. So, Ford switched to the use of steel ball bearings. In Gen 1 models, the turbochargers were pushed to the limit (and, sometimes, beyond), but Gen 2 and 3 models have larger turbochargers to provide more power. This has resulted in fewer problems.

Faulty EGT Sensors

Vehicles from the 2012 model year sometimes suffered from EGT sensor failures. This is especially true in emergency vehicles that came equipped with an ambulance package and to a lesser degree in other pickup models. Faulty EGT sensors are the one of most common reasons for check engine lights coming on as well as for stop safely warnings.

Coolant Leaks

When looking at models from 2011-2016, the inlet fitting design for the turbo coolant system is the most common leak culprit. If that’s not the cause, then a radiator leak is another possibility.

Yet another item to check: the water pump. Less common possibilities include the oil cooler T-line and the radiator hose O-ring.

Although not universally true, many problems listed so far are most commonly found in Gen 1 models from 2011-2014. For them, here are the appropriate Ford Powerstroke parts.

Gen 2 6.7 Powerstroke Problems

By 2015, Ford Motor Company had corrected many of the earlier problems and upgraded the engine in significant ways. If there are problems with 6.7 Powerstroke parts in 2015-2019 models, they tend to be with the EGR cooler flow, the fan clutch, and the crankshaft damper. Other challenges can arise because of the additional power and torque inherent in the turbo updates.

If you experience these problems (or other ones not listed) in your 2015-2019 pickup truck, here’s where the appropriate Ford Powerstroke parts are listed.

Gen 3 6.7 Powerstroke Problems

In 2020, Ford released the Powerstroke engine that truly offers the best-in-class power and it’s anticipated that many of the problems that took place in Gen 1 and Gen 2 engines have been addressed.
