7.3L Powerstroke Engine
The 7.3L Powerstroke Engine was introduced alongside the 7.3L IDI. You could say that the 7.3L Powerstroke is based on the design of the IDI, but the engines complete opposites by nature of their operation. By 1999, International had built 1million o the 7.3L Powerstrokes. The 2 millionth 7.3L Powerstroke rolled off the production line in 2002. The 7.3L Powerstroke Engine failed to meet strict federal emissions regulations, and was retired after the 2003 model year. The 7.3L Powerstroke laid the foundation for Ford’s prosperity in the diesel market. The 7.3L Powerstroke gives new meaning to the terms performance, reliability, and longevity. It is not uncommon for a 7.3L Powerstroke to serve well past the 500,000 mile mark without requiring major repair. The 7.3L Powerstroke for many owners is a million mile motor. The performance figures for the 7.3L Powerstroke are relatively low by todays standards, but the 7.3L Powerstroke is largely responsible for fueling the race between Ford, Dodge, and Gm in the marketplace.
7.3L PowerStroke Engine Serial # Location
The serial number of a 7.3L Powerstroke engine is located on the rear oil cooler pad (driver’s side rear of engine, the “pad” is where the oil filter assembly mounts to the engine block). The first 2 digits of the serial number are “7.3”, followed by a 4 digit manufacturing designator, and then a 6 digit build number. The sequential build number may be useful in learning more about what components your engine is equipped with, as some items were changed/upgraded throughout the engine’s life.
Additional 7.3L Powerstroke Engine Info:
The 7.3L Powerstroke is based on International’s T444E (the name “Powerstroke” is unique to Ford vehicles). The T444E has been offered in applications exceeding a 60,000 lb GVWR; the T444E and 7.3L Powerstroke are medium duty engine platforms. Pickups, school buses, dump trucks, the engines have been used in a variety of diverse applications.
Over 2 million 7.3L Powerstroke engines are still in operation today, more than Chevrolet/GMC Duramax and Dodge Ram Cummins equipped pickups combined.
Though greatly outdated by today’s standards, the 7.3L Powerstroke was the leader of innovation at the time of its introduction.
The 7.3L Powerstroke diesel is regarded as one of the best diesel engines utilized in the light/medium duty market due to an unsurpassed reputation of reliability, even in the most rugged of operating conditions. During its production, very few 7.3L Powerstroke experienced serious engine problems and the B50 engine life of 350,000 miles proved to be an extremely conservative rating. Though production of the 7.3L Powerstroke ceased in 2003, the engine remains highly sought after and they hold their value well.
