The engine's, regardless of model year, are temperamental - many of the sensors and problematic engine systems have been replaced by updated parts, so factory replacements are often of higher quality than the originals. The absence of a partner seems to have given Ford an advantage over competitors, granting them the freedom to design an engine that fits their specific needs and the needs of their customers. Also unique is the engine's exhaust and intake manifold designs. Additionally, it streamlines the warranty process, which was partially responsible for souring the relationship between Ford and International in regards to problems with the 6. Among the many selling points was a variable geometry turbocharger that provided quick throttle response and the TorqShift transmission, which provided crisp, positive shifts. The engines are assembled in Chihuahua, Mexico. .
Because of the flash update, very few engines likely exist with the original programming. Owners of the 390 hp model were able to receive a free dealer installed upgrade to achieve the new 400 hp power rating. Both horsepower and torque were once again increased for the 2018 model year, peaking at 450 hp and 935 lb-ft, respectively. In the performance department, the 6. The Ford, International partnership lasted nearly 30 years, but Ford seems to be doing just fine on their own.
The first Super Duty's sold featured the early 390 horsepower engine rating. It is said that the earliest 6. The unique exhaust flow design is said to increase thermal efficiency of the turbocharger. Fortunately, Ford seems to have hit a home run with the 6. While torque does not peak on the 6. The key to avoiding problems with the 6.
Viscosity recommendations vary with ambient temperature; refer to owners manual Engine Weight: Approx. As with any new engine, potential truck buyers initially questioned the platform's reliability despite reports of extensive durability testing. This helps lower combustion temperatures and increase engine longevity. As opposed to a tradition V engine, the intake and exhaust flows are reversed - the intake manifolds are located on the outer deck of the cylinder head and the exhaust manifolds exit directly into the engine valley where the turbocharger is mounted. Despite an overwhelming number of problems, the 6. This is the first Power Stroke not manufactured by long time partner, International Navistar.
However, it is difficult to prove any correlation between the engine's model year and the percentage of trucks experiencing technical difficulties. Ford suggests that software adjustments, cylinder head improvements, and increased turbocharger boost are responsible for the increases. A unique feature of the 6. Ford chose to design, engineer, and produce its own diesel engine to maintain profitability and a competitive edge in the growing diesel segment. The International variation of the 6. Oil is jetted into the bottom or the piston and travels through a cavity within the piston, cooling the top of the piston before exiting.
