Ford 6.7L Power Stroke Repair
The 6.7L Power Stroke is Ford's in-house diesel and has proven considerably more robust than its predecessors. The work we see most involves fuel system, emissions and cooling components rather than fundamental engine architecture. We service 6.7L Power Stroke trucks at our Glendale shop.
Common applications
- Ford F-250, F-350, F-450 and F-550 Super Duty (2011 and newer)
- F-650/F-750 medium-duty in certain configurations
Known problems and symptoms
Early applications in particular can suffer HPFP failure that contaminates the fuel system, which expands the repair scope significantly.
Variable geometry turbo actuator and bearing issues produce low power and boost-related codes.
EGR cooler, DEF injector and NOx sensor faults are the most common emissions-side repairs on this engine.
The dual cooling circuits on this engine need correct service. Overheating complaints deserve thorough diagnosis in Arizona conditions.
Less common than on older engines but still a real cause of cold-start issues.
How we diagnose it
- Full powertrain scan including emissions and aftertreatment data
- Fuel rail pressure and return flow testing
- Boost, backpressure and turbo actuator testing
- Cooling system pressure testing on both circuits
- DEF quality and dosing system diagnosis
Repair options
- Fuel system repair including full cleanup after pump failure
- Turbocharger and actuator replacement
- EGR cooler, DEF and NOx sensor repair to factory configuration
- Cooling system service and component replacement
- Engine repair or replacement when internal damage is confirmed

Frequently asked questions
What happens if the high-pressure fuel pump fails?
Metal debris can travel through the fuel system, which means injectors, lines and the tank may all need attention. We confirm the extent before quoting so there are no surprises mid-repair.
Do you service the transmission behind this engine too?
Yes — the 6R140 and later 10-speed units behind the 6.7L are transmissions we work on regularly.
