6.7 Powerstroke Problems

Written By: ProSource Diesel

Ford introduced the 6.7 Powerstroke diesel engine to their trucks in 2011. This engine’s technology was a giant step up from their previous 6.4L engine. The engine is such an improvement that Ford still uses it in 2023. This 970-pound engine has powerful capabilities, operates smoothly, and runs quietly; Diesel truck owners are thrilled by it even today.

The vast majority of 6.7 Powerstroke diesel engine owners never experience any problems. Most of the engine issues stem from its Gen 1 model and were fixed in the following generations. If you’re experiencing a problem with this engine and need a quick fix, this guide will give you easy answers.

When buying replacement diesel truck parts, make sure the part is compatible with your truck’s model year. The 6.7 Powerstroke is divided into three distinct generations by year:

Gen 1: 2011-2014 (2011-2016 6.7 Powerstroke parts)

Gen 2: 2015-2019 (2015-2019 6.7 Powerstroke parts)

Gen 3: 2020-2023 (contact us for these Ford Powerstroke parts)

When the 6.7 Powerstroke has issues, it’s usually one of the following:

Radiator & Coolant System Leaks

The earliest models of Powerstroke often developed radiator leaks; the severity of these leaks varies. Ford pickup trucks from 2012 and onward experience this issue significantly less.

Among the 2011-2016 model years, the inlet fitting design on the turbo coolant system sometimes led to leaks. You might also experience a leak in your radiator.

When checking for leaks, also check your water pump. Less-common causes might be your engine’s oil cooler T-line and the radiator hose O-ring.

Many of the problems listed so far are found on Gen 1 models from 2011-2014, but they can occur in later models as well. You can find the appropriate Ford Powerstroke parts here:

Glow Plug Problems

This is another issue that typically occurs in the engine’s earliest models. 2011 trucks experienced this issue the most. When the tips from the glow plug become separated, it becomes difficult to start up your engine. In later model years, the glow plug problems often occurred as a side-effect of exhaust valve failure.

Oil Leaks

Gen 1 models sometimes sprung leaks in the vacuum pump gasket, which was typically caused by loose bolts. You can mitigate the issue by tightening the bolts, but you’ll likely also need a replacement gasket.

NOx Sensor Problems

This failure occurred frequently during the 2011 model year. This issue became so severe, Ford created the Custom Satisfaction Program 12B33 to allow owners to have the NOx sensors checked and replaced. This initiative also gave them an upgrade for emission control.

Turbocharger Challenges

The ceramic ball bearings, especially the ones in the 2011 and 2012 model years, sometimes caused costly turbo failures. Ford eventually switched to steel ball bearings. Gen 1 Powerstroke 6.7 models had their turbochargers pushed to the limit, but the Gen 2 and 3 models added larger turbos to provide more power, resulting in fewer problems.

Faulty EGT Sensors

Vehicles in the 2012 model year sometimes experienced EGT sensor failure. This issue was especially common in emergency vehicles equipped with an ambulance package, less so in pickup models. If the check engine light is on, faulty EGT sensors are a common culprit. They might also activate “stop safely now” warnings.

Gen 2 6.7 Powerstroke Problems

By 2015, Ford had ironed out many of the early engine problems and made significant upgrades to the engine. Common problems in 2015-2019 6.7 Powerstroke include issues with the EGR cooler flow, the fan clutch, and the crankshaft damper. The updated turbo in these models created more power and torque, which sometimes led to issues too.

If you experience problems in this engine generation or any other generation, these are the appropriate Ford Powerstroke parts.
