Vehicle
Ford F-250 Super Duty
The heavy-duty truck line, and it is a different vehicle from the F-150 despite the name — different frame, different axles, different engines, and a separate service literature. Diagnosis is dominated by which diesel is fitted. The 6.0 Power Stroke is the one with the reputation: head gasket failure driven by stretching head bolts, EGR cooler cracking, and an oil-driven injection system whose high-pressure oil rail leaks make it crank without starting. The 6.4 adds a pair of turbochargers and a diesel particulate filter with its own regeneration faults, and the 6.7 from 2011 is Ford's own design and a substantially better one. The 7.3 before all of them is mechanically simple and the most durable of the family.
Generations
-
Seventh generation 1980–1986
Carburetted petrol and the mechanical 6.9 IDI diesel — neither sets a code, so diagnosis here is compression, timing and fuel delivery.

Pre-Super Duty 1987–1998
Before the Super Duty split the line, the F-250 shared the F-150's chassis; the 7.3 IDI diesel here is mechanical and sets nothing.

PHN131 1999–2019
The first Super Duty, and the longest-lived: North America stopped in 2007 and Brazil went on building it until 2019, which is why its engine list holds two South American diesels the US truck never had. The 7.3 Power Stroke gives way to the 6.0 in 2003, and that change is the one that matters most on this generation.

P356 2008–2010
Three model years, and the generation of the 6.4 Power Stroke — a sequential twin-turbo that lasted no longer than the truck it was built for.

P473 2011–2016
Ford stops buying its diesel in and builds the 6.7 Power Stroke itself, and the petrol V8 becomes the 6.2 Boss. The six-speed 6R140 arrives with them; the old five-speed stays only on the chassis cabs with the V10.

Fifth generation (P708) 2023–present
The 6.2 Boss gives way to a 6.8 Godzilla, so both petrol V8s are now the same family at two sizes, and every gearbox is a ten-speed. The 6.7 Power Stroke gains a High-Output version above the standard one.

Service information
Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- What actually fixed it — or that nothing did, which is worth knowing too.
