Ford Powerstroke Repair From the 7.3 to the 6.7
Powerstroke repair starts with knowing which of Ford's four heavy-duty pickup diesels is under your hood, because a 7.3, a 6.0, a 6.4 and a 6.7 each break in their own way. We diagnose and fix all four, from oil-actuated HEUI injectors to CP4 fuel systems, then tell you what needs attention now and what can wait.
Four heavy-duty engines wearing the same Powerstroke badge
Ford's heavy-duty pickups have carried four very different Power Stroke diesels. The model year tells you which one you own.
| Engine | Model years | How it makes fuel pressure | Emissions hardware |
|---|---|---|---|
| 7.3 | 1994.5 to 2003 (OBS through 1997, Super Duty 1999 to 2003; also E-Series vans and the Excursion) | HEUI: oil pressure drives the injectors and the IDM fires them | None. No EGR, no DPF |
| 6.0 | 2003.5 to 2007 | HEUI again: oil pressure drives the injectors and a FICM fires them | EGR valve and EGR cooler |
| 6.4 | 2008 to 2010 | High-pressure common rail with piezo injectors | Two EGR coolers, and the first Power Stroke with a DPF |
| 6.7 | 2011 on | Common rail fed by a Bosch CP4.2 pump, 2011 and newer | EGR, DPF, and DEF with SCR |
That year came with either the 7.3 or the 6.0, and we confirm which.
Pick your Powerstroke, see what we watch for
The short version. Each generation has its own page with the full rundown.
7.3: simple, and it runs on oil pressure
No EGR and no DPF, which is why owners keep them forever. Oil pressure drives the injectors, so many hard starts and stalls trace back to the high-pressure oil pump (HPOP), the IPR valve or the ICP sensor. Details on our 7.3 Powerstroke repair page.
- Hard or no start once it is warm
- Stalling or stumbling at idle
- Oil leaks around the high-pressure oil system
- Rough running from tired injectors
6.0: fixable, if you fix the cause
The 6.0 earned its reputation with stretched head bolts and EGR coolers that fail and can take out the oil cooler. A FICM fires the injectors and a Garrett VGT handles boost. Head studs and real cooling work make it a keeper. See our 6.0 Powerstroke repair page.
- Coolant pushing out of the degas bottle
- Coolant loss with no puddle under the truck
- Hard starts and misfires from low FICM voltage
- Turbo that sticks and loses boost
6.4: strong engine, tight packaging
Ford's first common rail Powerstroke: piezo injectors, BorgWarner compound turbos, two EGR coolers and the first DPF on a Power Stroke. Radiators leak, and big jobs often mean lifting the cab. More on our 6.4 Powerstroke repair page.
- Coolant leaks at the radiator
- DPF and regen warnings
- EGR cooler failures and coolant loss
- Fuel and injector faults on the common rail
6.7: the current engine, and fussy about fuel
A Bosch CP4.2 pump, a turbo in the valley between the heads, a separate low-temperature cooling loop and DEF from 2011. Water or bad fuel can wreck the CP4 and spread debris through the system, so we cover Ford 6.7 CP4 failure in its own article. Specifics live on our 6.7 Powerstroke repair page.
- Hard start, no start or a sudden stall
- DEF, SCR and NOx sensor warnings
- Coolant leaks in either cooling loop
- Turbo noise or low boost
Where your symptom sends us
The complaint tells us which system to open first.
Lights, limp mode, odd behavior
A code points at a circuit, not a part. Our diesel diagnostics prove what failed before money goes into parts.
Low power, hard start
Fuel pressure and supply, including the 6.7 CP4. See diesel fuel system repair.
Misfire, smoke, rough idle
Oil-actuated HEUI injectors on the 7.3 and 6.0, high-pressure common rail on the 6.4 and 6.7, each tested differently. See diesel injector repair.
No boost, whistle, smoke
Sticking VGTs on the 6.0, compound turbos on the 6.4, the valley-mounted turbo on the 6.7. Start with diesel turbo repair.
Coolant loss, regen warnings
The 6.0 and 6.4 are famous for EGR cooler replacement. DPF, DEF and sensor faults fall under diesel emissions repair. We do not do delete work.
Slipping, flare, hot fluid
Towing works the automatic hard on every generation. Read about diesel transmission repair.
How mountain miles show up on a Ford diesel
Ford diesels have rolled through our bays since 2007, most of them working trucks. A camper or trailer over the passes holds heat high for miles, and that is when a weak EGR cooler, tired radiator or sticking turbo quits.
- Cold mornings are hard on HEUI engines, because cold, thick oil slows the oil pressure that drives the 7.3 and 6.0 injectors
- Short winter trips keep a 6.4 or 6.7 from finishing its DPF regen
- We take on the problems other shops and dealerships could not solve

I can’t say enough good things about Bodacious Diesel. They’re team is knowledgeable, honest, and incredibly thorough. They took the time to explain exactly what was going on with my truck, gave clear options, and never tried to upsell unnecessary work. The repairs were done right and at a fair price. You can tell they genuinely care about their customers and take pride in their work. If you’re looking for reliable diesel mechanics you can trust, Bodacious Diesel is the place to go.5 STARS
What sets the price of a Powerstroke repair
We quote after testing. One warning light can mean a sensor or a head.
| Cost factor | Why it matters on a Powerstroke |
|---|---|
| Which generation | A 7.3 is open and easy to reach. A 6.4 often needs the cab off for the big jobs. |
| The failed part or its cause | A cracked 6.0 EGR cooler with a plugged oil cooler behind it means both get replaced, or the new cooler fails too. |
| Contamination | When a 6.7 CP4 sheds metal, the clean-up reaches far past the pump. |
| Shared labor | Two repairs behind one teardown cost less done together. |
Most work is drop-off. We are open Monday to Friday, 8:00 AM to 6:00 PM, and you hear the findings and cost before any work begins.

Powerstroke questions owners ask us
Short answers here; each generation page goes further.
Go by model year: the 7.3 ran 1994.5 to 2003, the 6.0 ran 2003.5 to 2007, the 6.4 ran 2008 to 2010 and the 6.7 has been in Super Duty trucks since 2011. A 2003 can have either the 7.3 or the 6.0, so we check the engine itself before any Powerstroke repair gets quoted.
Often, yes. Most 6.0 trouble comes from stretched head bolts and a clogged oil cooler that kills the EGR cooler. Fix those causes, with head studs and cooling work done together, and you have a truck worth keeping.
Diagnosis typically takes 24 to 72 hours depending on workload. Repair time then depends on the job and parts availability; a cab-off 6.4 job takes longer than a sensor on a 7.3. You get the timeline with the plan.
Watch it, do not panic. The 6.7 uses a Bosch CP4.2, 2011 and newer, and it does not tolerate water or poor fuel. Change fuel filters on schedule and call at the first hard start or fuel pressure code.
We do not do delete work. Powerstroke repair here means fixing EGR, DPF and DEF systems so they work as built, and finding what made them fail.
