All About The History of Ford Power Stroke Diesel Engine

The history of Ford Power Stroke engine dates back to 1994. Before the first generation of the Power Stroke engine, there was the 6.9L IDI, was produced from 1982-1987. This engine was developed in collaboration with International Truck and Engine Corporation.

The first generation Power Stroke engine, known as the 7.3L Power Stroke, was introduced in 1994. The 6.0L and 6.7L Power Stroke engines were introduced in 2003 and 2011 as the second and fourth generation Power Stroke engines. The most recent additions are the 3.2L and 3.0L Power Stroke.

This article will go over the history of the Ford Power Stroke engine and the features of each engine.

Who Makes The Power Stroke Engine?

Ford and ITEC (International Truck and Engine Corporation, ITEC is owned by Navistar) formed a partnership in 1982 to produce diesel engines.

The Ford’s Power stroke history begins with the 6.9-liter IDI engine; it had 170 hp and 315 lbs torque. This engine was manufactured until 1987, when the 7.3-liter IDI engine superseded it.

The 7.3-liter Powerstroke followed in 1994; it had a turbocharger and upgraded interior features. This was the beginning of a revolution in the engine world.

Ford’s Power Stroke Engine History:

The 7.3-liter Powerstroke

The 7.3-liter IDI engine, which had been in use since the 1980s, was replaced by the 7.3-liter Powerstroke engine in 1994. It had a cast iron block, cylinder heads, a high-pressure oil pump, and a common rail fuel injection system.

These modifications enabled the engine to produce more power and torque than the IDI engine while improving fuel efficiency and lowering emissions.

Ford released a new version of the engine in 2001, which included a more powerful turbocharger, an air cooler, and fuel injectors. These improvements increased its power output to 275 horsepower and 525 lb-ft of torque.

The engine received a new high-pressure and low-pressure oil pump and other refinements in 2003, which increased its durability and reliability. The 7.3-liter Powerstroke was phased out of production in 2003 but remains to be the best Powerstroke engine ever made.

The 6.0-liter Powerstroke

Navistar, formerly known as ITEC, collaborated with Ford to develop the 6.0-liter Powerstroke engine in 2003. Stricter emissions regulations drove the decision to abandon the popular 7.3-liter engine.

One of the most noticeable changes in 6.0L was converting the engine block and cylinder heads from cast iron to aluminum. This reduced the engine’s weight by more than 100 pounds, which improved fuel economy and overall vehicle performance.

The 6.0-liter Powerstroke also included a high-pressure common rail fuel injection system, allowing more precise fuel delivery control and increased power output.

Thanks to the variable geometry turbocharger and emissions control features, which contributed to better low-end torque and overall performance, the 6.0-liter Powerstroke produced 325 horsepower and 570 pound-feet of torque.

Unfortunately, the 6.0L was the worst of all Powerstroke engines. The most common 6.0-liter Powerstroke problems were reliability issues, especially with the high-pressure fuel injection system and the head gasket.

Also, the engine was susceptible to head gasket failures, which could result in coolant leaks and engine damage. Many owners reported injector problems and issues with the oil and ERG cooler.

Ford issued several recalls, and in 2007, they abandoned the 6.0L Powerstroke.

The 6.4-liter Powerstroke

Once again, Navistar collaborated with Ford to make the 6.4-liter Powerstroke diesel engine in 2008. With a power output of 350 horsepower and 650 lb-ft of torque, they designed the 6.4L Powerstroke to be more powerful and efficient than its predecessor.

It included several new technologies: a high-pressure common rail fuel injection system and a variable geometry turbocharger. The 6.4 Powerstroke also had new block and cylinder heads designed to improve durability and reduce emissions.

The estimated 6.4 Powerstroke life expectancy was around 150,000-200,000 miles when properly maintained and used in normal conditions.

The 6.4L Powerstroke was phased out in 2010 and was replaced by the 6.7L Powerstroke. Also, the Ford-Navistar collaboration ended.

The 6.7-liter Powerstroke

Ford introduced their own built 6.7-liter Powerstroke diesel engine in 2011. The 6.7-liter Powerstroke includes a high-pressure common rail fuel injection system, a variable geometry turbocharger, a humidifier cooler, and an exhaust gas recirculation system, among other advanced technologies.

Also, selective catalytic reduction (SCR) technology is one of the key features of the 6.7-liter Powerstroke.

This system employs diesel exhaust fluid (DEF) to reduce nitrogen oxide (NOx) emissions, allowing the engine to meet stricter EPA emissions standards (EPA). Power ratings for the engine range from 385 horsepower and 405 lb-ft of torque to 450 horsepower and 935 lb-ft of torque.

The 6.7-liter Powerstroke has received several updates to improve performance and reliability. Ford, for example, introduced a software update in 2013 to improve the engine’s fuel economy, and the engine was updated in 2017 with a new high-pressure fuel injection system.

The Present 3.0L And 3.2L Power Stroke

The 3.2l and 3.0L are the most current Power stroke engine, which was introduced to the market in 2015 and 2018, respectively. Here are some known facts about them:

● The 3.2L Powerstroke

The 3.2 Power Stroke engine is a five-cylinder diesel engine and was first introduced in 2015. It is commonly known as the Duratorq in many markets and was designed for use in the Ford Transit and Ford Ranger pickups.

The 3.2 Power Stroke engine has a horsepower of 197 and generates 350 lb-ft of torque; the engine features a high-pressure common rail fuel injection system, a turbocharger with variable geometry, and a water-cooled EGR system.

● The 3.0L Powerstroke

Ford 3.0 Power Stroke engine is a 3.0-liter, V6 turbo diesel engine with 250 horsepower and 440 pound-feet of torque. It is used in light-duty trucks such as the Ford F150.

It has a lightweight graphite iron construction and cast aluminum cylinder heads. It also features a forged crankshaft with specially designed rods and bearings, a variable-geometry turbocharger, and a Bosch-supplied common-rail direct injection system (29,000 psi).
