- Coolant Leaks. Cost to fix: $400-$2,000
Leaks/Poor Bearings
Problem:
One of the most problematic areas of the system is trouble with leaks and poor bearings. Issues in the coolant inlet and primary stock radiator can lead to significant leaks, and it’s possible for the glow plugs to break. Issues with the engine and ceramic bearing-balls can lead to catastrophic disaster.
Look for leaks and engine failure to determine if this could be a problematic area in the vehicle. If you suspect there could be a leak, we recommend taking your car to a mechanic as soon as possible to have them diagnose and repair the machine. Leaks and poor bearings can be disastrous if left alone for too long in a system.

Cost:
It shouldn’t be too expensive to invest in a fix for leaks and poor bearings in your system. The average cost ranges from $300-$400, which is far less than significant engine troubles. This trouble isn’t nearly as pricey as many engine issues, but it should still be touched on right away,
Injection Pump Failure
Problem:
Injection pump failure is one of the worst areas in the list of Ford 6.7 diesel problems, also known as the “Achilles Heel” of the system. It tends to break down tanks due to significant metal-on-metal impact from the air inside the fuel pump. The air contamination can wreak havoc.
There are several clear signs of injection pump failure. Watch for indications like tricky starts, sputtering noises, stalling, power loss, fuel tank noise, lower fuel efficiency, and more. Don’t let this trouble go on for too long.
Cost:
Unfortunately, handling a repair on the injection pump can be one of the more expensive selections. Much of the cost is thanks to the labor associated with the system. Prepare to spend anywhere in the ballpark of $1,800-$2,500.
First-Gen Sensor Engine Problem
Problem:
Thanks to significant upgrades to the system, there haven’t been many troubles in the electric system in the newest versions of the Ford 6.7. However, the first generation of the vehicle created electrical issues that led to a significant decrease in the vehicle’s power ability. Refrain from investing in the first generation if you can.
Signs of engine issues will be a lack of power in the system, the car failing to start, sputtering, and even breaking down and stalling in the middle of the road. Engine issues aren’t fun to handle so, again, try to avoid the first generation to refrain from the sensor issue.
Cost:
Engines are one of the most expensive parts of a vehicle. It can take $3,000-$8,000 to repair the sensor in your system.
FORD 5.4 ENGINE PROBLEMS
The powerplant enjoyed a 20-year run in everything from Ford F-150 picks to Lincoln Navigators. But this period is marked by many Ford 5.4 engine problems.
EGR Cooler Troubles
Problem:
The EGR cooler is another area of failure in the long list of Ford 6.7 diesel problems, which is concerning in many areas of the vehicle. They do not fail, but many individuals report a significant buildup of soot in the system. If the soot becomes too extreme, you must replace the entire thing.
There are several clear indicators of EGR cooler troubles. Keep your eyes peeled for coolant leakage on the outside, white steam and smoke, engine lights, and a far lower coolant level.
Cost:
The price range for repairing this system can vary dramatically depending on the level of buildup. Anticipate paying around $270-$4,000.
Coolant Leaks
Problem:
Finally, coolant leaks from the radiator are highly problematic for the average owner. This engine is massive, so it makes sense that it produces significant heat. Coolant keeps it at a safe temperature but will quickly break if it isn’t maintained. If coolant levels leak, the system won’t be able to care for itself effectively.
Leaks could be a hole in the physical radiator, deteriorating hose pieces, or anything in between. Watch for puddles under your vehicle and check out the temperature gauges as you go. If your fluid drops faster than it should, consider a possible coolant leak to be the issue.
Cost:
Coolant leak costs vary depending on the severity of the leak and what’s causing it. Thus, anticipate paying around $400-$2,000 for this repair.

Avoiding Ford 6.7 Diesel Issues
The best way to reduce the troubles in your Ford 6.7 diesel is to keep your eyes out for issues. If you see any indicators of a problem, take the vehicle to a professional as soon as possible.
It’s always tempting to try to fix things yourself. However, if you aren’t completely confident in your actions, seek a professional. Otherwise, you are far more likely to break it further.
Final Thoughts
Though the Ford 6.7 is one of the top selections from the brand, there are still significant Ford 6.7 diesel problems to consider. Watch for leaks/poor bearings, injection pump failure, first-gen sensor engine problems, EGR cooler troubles, and coolant leaks.
It might be tempting to let trouble go on for a long time without addressing it. However, we don’t recommend that avenue. The longer you allow something to sit, the more likely it will impact your vehicle for the worse and the more expensive. Sooner is always better when repairing your Ford 6.7 diesel system.
