Is the 2017 Ford 6.7 diesel a good engine?
Generally speaking, yes: the 2017 Ford 6.7L Power Stroke is a solid, capable diesel for heavy-duty pickups, delivering strong torque and reliable towing when properly maintained.
The question of the 2017 6.7L Power Stroke centers on real-world durability, performance under load, and the long-term maintenance costs associated with modern diesel emissions systems. Ford’s 6.7L Power Stroke, introduced to replace earlier diesel designs, matured into a high-torque, heavy-haul engine by the 2017 model year. Owners commonly praise its towing ability and robust low-end torque, while recognizing that diesel technology—particularly high-pressure fuel systems and aftertreatment components—can require attentive maintenance and occasional expensive repairs as miles accumulate. This article examines how the 2017 6.7L performs in practice, where it excels, and what buyers and owners should watch for.
Engine Performance and Design
Power, torque, and overall versatility define the 6.7L Power Stroke. For 2017, Ford rated the engine at roughly 440 horsepower and about 860 lb-ft of torque, enabling strong acceleration with heavy payloads and confident towing. The engine uses a modern common-rail fuel system and a turbocharger to deliver power while meeting emissions requirements, paired with Ford’s heavy-duty chassis. Real-world fuel economy varies with load, weight, and driving conditions, but many owners appreciate its balance of capability and daily drivability for a diesel-powered pickup.
Power and Torque Figures
In the 2017 model year, the Power Stroke delivered around 440 hp and 860 lb-ft of torque. This output is designed to provide substantial towing and payload capability while maintaining driveability for everyday use. Peak torque is available at relatively low engine speeds, aiding start-up performance and hill climbs with heavy trailers.
Pros and Strengths
The following points are commonly cited by owners, technicians, and automotive publications as the engine's strengths:
- High torque at low RPMs, which helps with towing and heavy payloads.
- Strong long-term durability when properly maintained, with many trucks reaching high mileages.
- Good aftermarket and dealer support, and readily available parts and service.
- Solid overall performance for both daily driving and work use, with competent highway manners for a heavy-duty diesel.
- Robust cooling and exhaust aftertreatment integration that supports sustained heavy use.
These strengths make the 6.7L Power Stroke a compelling choice for buyers prioritizing torque and hauling capability, provided maintenance is kept up and potential issues are managed early.
Drawbacks and Maintenance Considerations
As with any modern diesel, the 2017 6.7 Power Stroke has potential trouble spots that owners should monitor, particularly as mileage climbs. Here are the main concerns to be aware of:
- High-pressure fuel system vulnerabilities (CP4 HPFP) that can fail and trigger costly repairs if contaminants or wear cause pump failure.
- EGR/DEF system components, including the EGR cooler and related plumbing, which can develop leaks or clogging tendencies that affect performance and emissions.
- Oil and cooling components, such as the oil cooler and related seals, with potential for leaks under heavy use or high mileage.
- Turbos and actuators that can wear or fail with age, though less common than in earlier diesel generations.
- Higher maintenance and repair costs, especially for major failures, due to specialized diesel components and labor.
Regular preventive maintenance and prompt attention to warning signs can mitigate many of these risks, but potential buyers should be prepared for diesel-specific maintenance costs as the truck ages.
Maintenance Tips for Longevity
A proactive maintenance approach is essential to maximize the lifespan of the 6.7 Power Stroke. The following practices are commonly recommended by technicians and owners alike:
- Keep up with manufacturer-recommended maintenance intervals for oil changes, fuel filters, and DEF dosing fluids.
- Use high-quality fuel and ensure the fuel system is clean to minimize CP4 wear and fuel-contaminant risks.
- Monitor exhaust aftertreatment temperatures and service EGR/DEF components to prevent clogging or leaks.
- Address cooling system issues promptly, including oil cooler and radiator checks, to prevent overheating in heavy-use scenarios.
- Follow Ford service bulletins for software updates that optimize engine management and emission controls.
Adhering to these maintenance steps can help reduce the likelihood of major failures and preserve resale value for a high-mileage 2017 diesel.
Summary
The 2017 Ford 6.7L Power Stroke is generally a solid, capable engine for heavy-duty pickup use, offering ample torque and reliable towing when well maintained. It benefits from modern diesel technology, strong factory support, and a track record of durability for many owners. However, diesel systems—particularly high-pressure fuel pumps, EGR/DEF components, and cooling systems—can lead to costly repairs if neglected. With diligent maintenance and prompt attention to potential issues, the 6.7L Power Stroke remains a competitive choice in the used-diesel market for buyers prioritizing torque, payload, and long-haul capability.
