The 6.0-liter Power Stroke replaced the 7.3-liter in Super Duty pickups partway through the 2003 model year. It is a turbocharged V8 with a smaller displacement than its predecessor but a higher rating, at 325 hp and 560 lb-ft initially, and 570 lb-ft for 2005 through 2007. It was used in F-250 and F-350 Super Duty trucks with a four-speed automatic or a manual transmission, and was replaced by the 6.4-liter engine for 2008.
What made it successful
Its higher power output compared with the 7.3-liter gave Ford a clear rating advantage over its own previous engine.
Market position
Its peak ratings sat above the previous Ford diesel. How it compared with competitors' ratings of the same years is not yet sourced.
Rebuild Potential
Tier BEditorial opinion.
The 6.0L has excellent parts and community support and a well-documented repair path. It ranks below the 7.3L because the head gasket, EGR cooler, and oil cooler faults are inherent to the design and can be costly. Once those fixes are done it becomes a viable candidate, with the emissions equipment kept in place.
Best year ranges
- 2005-2007: Commonly said to be the better builds among these engines; not confirmed against a primary source, and the same failure points still apply.
Known weak points
The oil cooler clogs, which can cascade into EGR cooler and head gasket failures.
Common fix: Replace the oil cooler and EGR cooler with upgraded units and service the coolant system.
Factory head bolts can stretch, leading to head gasket failure.
Common fix: Replace with head studs and upgraded head gaskets.
Common upgrade categories
- Upgraded oil cooler and EGR cooler
- Head studs and multi-layer head gaskets
- Coolant filtration and service
- HPOP, injector, and FICM service
- Transmission cooling
Keep the emissions equipment the truck was built with. Removing or defeating it on a vehicle originally equipped with it is illegal under federal law. Rules vary by state (for example California/CARB), so check local law and model-year requirements before modifying.
