2008 Ford F-450 Super Duty Service and Repair Manual

This factory service and repair manual for the 2008 Ford F-450 Super Duty covers the arrival of the turbocharged 6.4L V8 diesel, offered next to the 6.8L V10 on gasoline. A pickup body returns to the list as well, the four-door crew cab, joining three chassis configurations, and King Ranch appears among four trims with Lariat, XL and XLT. With a diesel new to the range, the specifications, torque values, wiring diagrams and diagnostics are grouped by system so each engine's data stays distinct from the other's.

Known issues on the 2008 F-450 Super Duty. Three recalls are on federal record for this model year. One is a seating systems compliance recall, where the seat side pivot bracket may crack or break in a crash; another covers 6.4L diesel trucks whose positive battery wire sits close enough to a splash shield bolt to chafe through to bare copper; the third also concerns the 6.4L, where excess hydrocarbons in the exhaust can drive particulate filter temperatures up, bringing lack of power, rough running, unusual noises and white smoke. Owners have filed 68 complaints with NHTSA, heavily on engine and engine cooling, then the power train. Exhaust, charging and driveline diagnostics all appear here.
