About the Powerstroke 7.3L Engine
The 7.3L Power Stroke is the most legendary diesel engine Ford ever put in a pickup truck. Manufactured by International/Navistar (designated T444E), the 7.3L was produced from 1994 to 2003 and earned a reputation for bulletproof reliability that no other light-duty diesel has matched. The engine uses a unique HEUI (Hydraulically-actuated Electronically-controlled Unit Injector) fuel system that uses high-pressure engine oil to fire the fuel injectors — a design that was revolutionary at the time. With no EGR, no DPF, and no DEF, the 7.3L is the simplest modern diesel to own and maintain. Many 7.3L trucks have exceeded 500,000 miles on the original engine, and the platform has developed a massive following among diesel enthusiasts, work truck owners, and the military.

Common Powerstroke 7.3L Issues (Addressed in Our Remanufactured Engines)
- CPS (Camshaft Position Sensor) failure — most common cause of no-start or stalling
- ICP (Injection Control Pressure) sensor failure — causes rough running and power loss
- IPR (Injection Pressure Regulator) valve sticking — causes hard starts and rough idle
- Turbo pedestal O-ring leaks — causes oil leaks and reduced boost
- EBPV (Exhaust Back Pressure Valve) can stick — causes excessive exhaust restriction
- Under Valve Cover (UVC) harness chafing — causes injector misfires

Powerstroke 7.3L Buying Guide
When purchasing a remanufactured 7.3L Power Stroke, the most important factor is the condition of the HEUI fuel system. The high-pressure oil pump, IPR valve, and ICP sensor should all be new or remanufactured. A quality remanufactured 7.3L should include new UVC harnesses, a new CPS, and updated turbo pedestal O-rings. The 7.3L is identified by VIN code 'F' in the 8th position. The 1999.5-2003 models are generally preferred due to the updated Super Duty chassis and improved electronics. Always verify whether the engine is a California emissions model, as these have slightly different components.
Frequently Asked Questions — Powerstroke 7.3L
How much does a remanufactured 7.3 Powerstroke engine cost?
A remanufactured 7.3L Power Stroke engine typically costs between $5,500 and $8,000 depending on the model year and configuration. The 1999-2003 Super Duty versions are slightly more expensive than the 1994-1997 models. All our 7.3L engines include new HEUI components and a comprehensive warranty. Call (631) 991-7700 for an exact quote.
Is the 7.3 Powerstroke the best diesel engine ever made?
The 7.3L Power Stroke is widely considered one of the most reliable diesel engines ever put in a pickup truck. Its combination of simple design (no EGR, no DPF, no DEF), proven HEUI fuel system, and legendary longevity (many exceed 500,000 miles) make it a top choice for reliability. While newer engines offer more power, few match the 7.3L's reputation for trouble-free operation.
How many miles can a 7.3 Powerstroke last?
A well-maintained 7.3L Power Stroke can last 400,000 to 500,000+ miles on the original engine. Many commercial and fleet trucks have exceeded 500,000 miles. The key to longevity is regular oil changes (the HEUI system depends on clean oil), clean fuel, and addressing CPS and ICP sensor issues promptly.
What years did Ford use the 7.3 Powerstroke?
Ford used the 7.3L Power Stroke from 1994 through 2003. It was installed in F-250/F-350 trucks (1994-2003), F-450/F-550 (1999-2003), Excursion (2000-2003), and E-350/E-450 vans. The engine was manufactured by International/Navistar under the designation T444E.
What replaced the 7.3 Powerstroke?
The 7.3L was replaced by the 6.0L Power Stroke in 2003. Ford made the change to meet stricter emissions standards and to increase power output. While the 6.0L offered more horsepower, it proved less reliable than the 7.3L, leading many owners to prefer the older engine.
Can you put a 7.3 Powerstroke in a newer Ford truck?
While technically possible, swapping a 7.3L into a newer truck is a major project requiring custom wiring, transmission adapters, and ECM programming. The 7.3L uses a unique HEUI fuel system and older electronics that don't directly interface with newer Ford truck systems. It's generally more practical to find a 1999-2003 Super Duty and install a remanufactured 7.3L.
