From daily-driven work trucks to high-output performance builds, proper fluid maintenance is one of the most effective ways to extend Powerstroke engine life, cooling efficiency, injector longevity, a

If the O/D OFF light on your shifter is flashing, your truck is not just asking for attention. It is telling you the PCM saw a transmission-related fault. A solid light usually means overdrive was man

In 1995 Ford began implementing the OBDII system in most of their vehicles. By 1996, due to a federal mandate, all vehicles were using the system. OBDII or On Board Diagnostics 2, gave us tons more da

Outside the completely fixable issues we all know about that have given it a bad reputation (oil cooler failures, EGR issues, turbo failures, head gasket issues) the 6.0L Powerstroke is known for its

If you’ve ever heard an old Ford guy say “check that cruise control switch before it checks your garage for smoke detectors,” this is what they’re talking about. Easilly the most commonly delt with re

Some 1994.5–1997 OBS 7.3 Powerstroke trucks used an early-style EOT sensor that is now obsolete. If your truck still has that old Engine Oil Temperature sensor and it fails, the correct repair is to u

The 7.3L Powerstroke is one of the most reliable diesel engines ever built, but as these engines get older, many issues become more and more common. Hard starts being near the top of that list. But th

The 7.3L Powerstroke ran long enough that people started treating all of them the same. That is how wrong parts get ordered. A 1996 OBS 7.3 and a 2002 Super Duty 7.3 share the same basic engine family

The ICP sensor is one of the more important sensors on a 7.3L Powerstroke, and also one of the easier ones to diagnose. ICP stands for Injection Control Pressure. The sensor is threaded into the high-

The 7.3L Powerstroke has earned its reputation the honest way: by generally refusing to die for decades. But even the best diesel ever stuffed into a Ford pickup is still attached to 20-plus-year-old

The 7.3L Powerstroke will usually drag the trailer wherever you point it. The 4R100 however, needs a little more respect. It is not a bad transmission by any means, but heat, old fluid, weak cooler ca

A 7.3L Powerstroke that cranks but won’t start does not automatically need a cam sensor, injectors, or an HPOP. It needs diagnosis. The 7.3 is simple compared to newer diesels, but it still needs four

The 6.0L Powerstroke is not the engine you diagnose with hopes, guesses, and a Facebook comment that starts with “my buddy’s did that.” A good scan tool is mandatory. Not just for codes, but for live

A good scan tool can save you a pile of money if you know what numbers actually matter. Codes are useful, but live data is where the 7.3 starts telling on itself. Hard start, no-start, low power, smok

The High-Pressure Oil Pump (HPOP) is the heart of the HEUI (Hydraulically Actuated, Electronically Controlled Unit Injector) fuel injection system used on both the 7.3L and 6.0L Powerstroke. When the

Glow plugs. Things that are often forgotten until running or starting issues arise. Hard cold starts, cold no starts, smoky when cold, rough running when cold, all are common concerns that could be as
