2004 Ford F-450 Super Duty Service and Repair Manual

This factory service and repair manual for the 2004 Ford F-450 Super Duty settles on two engines after the previous year's overlap: the turbocharged 6.0L V8 diesel and the naturally aspirated 6.8L V10 gasoline engine. The three chassis bodies carry over in four-door crew cab, four-door extended cab and two-door conventional forms, and the trims run Base, Lariat, XL and XLT. Specifications, torque values, wiring diagrams and diagnostics are laid out system by system, so a diesel job and a gasoline job start from the same index.

Known issues on the 2004 F-450 Super Duty. Three recalls are on federal record. The weightiest covers trucks with 6.0L diesel engines that may stall without warning while being driven and may not restart, traced to the wiring; the others involve tail lamp service parts sent to dealers and an aftermarket seven-way trailer adaptor whose incorrect wiring can leave trailer lights inoperative. Owners have filed 33 complaints with NHTSA, and the fuel system accounts for more than half of them, ahead of engine cooling and the wiring. Fuel delivery, harness routing and stall diagnostics are the sections that map onto those reports.
