6.7 Powerstroke Years to Avoid (Why You Should)

While the 6.7L Powerstroke engine might have been praised and hyped as the best version in the Power Stroke series, the engine is not entirely flawless. Some specific model years of the 6.7 Powerstroke engine are flagged as the “worst” you can buy/have in your vehicle.

So, what are the worst 6.7 Powerstroke years to avoid?

The 2011 through 2014 models seem to have many problems; hence, they are easily the worst models you should avoid. Also, the 2011 – 2014 6.7L Power Stroke models are the older generation; the new-gen models from 2015 are much better and hold up pretty well.

6.7L Powerstroke Generations

There are three generations of the 6.7L Powerstroke engine; the first-gen models are the most problematic ones to choose from; you should avoid them. However, some people seem to not have any problems with the first-gen models in their trucks.

  • First Generations: 2011 to 2014
  • Second Generation: 2015 to 2019
  • Third Generation: 2020 to date

The third-gen models are redesigned; they appear more decent and “good looking” than the older models. Also, the third-gen models are more efficient and produce more power for all kinds of activities.

Common 6.7 Powerstroke Years to Avoid

These model years are flagged as the worst years because they are unreliable and typically had a lot of issues – some of which could cost over $1,500 to fix.

It is advisable to avoid these 6.7 Powerstroke years – most especially if you’d be getting the engine in a used Ford truck.

Hereunder are the years of 6.7 powerstroke to avoid:

  • 2011 6.7L Power Stroke
  • 2012 6.7L Power Stroke
  • 2013 6.7L Power Stroke
  • 2014 6.7L Power Stroke

Why are these 6.7 power stroke years regarded as the ones to avoid? Well, below are the common problems you may face with these model years.

Problems With 6.7L Powerstroke Engines

1. Turbocharger Problems

Well, it’s the first generation; one should expect that the components haven’t been perfected yet. Yes, the first-gen turbocharger in the 6.7L typically fails after many miles.

The turbo failure starts in the charger (ceramic) bearings and exhibits some symptoms before it fails completely.

2. EGT Sensor Problems

The EGT (Exhaust Gas Temperature) sensor relays the exhaust gas temperature to the ECU/PCM; if this sensor fails, it will affect the engine’s after-treatment system, which may cause the check engine light to illuminate on the affected car’s dashboard.

Getting this sensor fixed costs approximately $200 (including labor and parts costs).

3. Overheating Due To EGR Cooler Clogs or Failure

The EGR Cooler is the device that helps the 6.7 power stroke to comply with the Euro 6 emissions standard.

It does this by cooling down the exhaust gas being recirculated into the engine; as the exhaust gas cools down, the NOx content drops significantly, resulting in environmentally friendlier emissions.

But then, when the EGR cooler is clogged or damaged, the engine would start producing more harmful emissions. EGR cooler failure can also lead to engine overheating and stalling. If left to linger, this problem could break down the engine completely. Getting a new EGR cooler costs less than $150.

4. Pump Failures

The fuel pump or injector/injection pump typically fails after many miles on the older-gen 6.7L Powerstrokes.

Failure of both or either of these pumps can cause engine stalling, rough idling, hard starting, or loss of power while driving (acceleration). Fixing this problem can cost up to $1,500 or more, depending on the level of damage.

5. Radiator Coolant Leaks

Some old-gen 6.7 power stroke engine owners complain of constant low coolant levels. This happens due to leaks in the primary radiator. The 6.7L Power Stroke engine comes with dual radiators; the primary radiator seems more unreliable than the secondary one.

Most Reliable 6.7 Powerstroke Years

The models in the second and third generations of the 6.7 Powerstroke series seem to hold up pretty. One can easily say that the years after 2014 (which ended the first-gen era) are the best years to buy. In other words, from 2015 thru 2022, 6.7 Powerstroke years are the best to buy.

These newer models are more reliable, fortified, charged, and flaunt a much better-looking appearance. There are just more improvements on 2015-to-date models that make them much better. Also, starting from the 2017 model, Ford redesigned the 6.7L turbo-diesel engine.
