What Years Did Ford Have Problems With Diesel Engine?

Between 1999 and 2003, Ford had problems with their diesel engines. The main issue was with the engine’s glow plugs, which would fail and cause the engine to misfire. This problem was especially prevalent in cold weather.

Ford issued a recall for the affected vehicles in 2001, but many owners reported continuing issues even after the recall was carried out. In 2003, Ford finally released an updated design for the glow plugs that resolved the issue.

In addition, it was named Engine of the Year by both Diesel Power magazine and WardsAuto World in 2012. So if you’re looking for a reliable diesel engine for your Ford truck, you can’t go wrong with the 6.7 liter Powerstroke.

Ford Diesel Engines by Year

Diesel engines have been around for many years, but they really came into their own in the 1970s. That’s when Ford began offering them in their light-duty trucks. The first was the 6.9L IDI V8, which was available from 1982 to 1987.

This engine was followed by the 7.3L Power Stroke V8, which was available from 1988 to 2003. The 6.4L Power Stroke V8 replaced the 7.3L in 2004 and was used until 2007, when it was replaced by the 6.7L Power Stroke V8. The current engine is the 3rd generation of Power Stroke diesel, and it’s available in both F-250/350 and F-450/550 trucks.

If you’re looking for a durable and powerful diesel engine for your truck, Ford has a great option for you!

6.0 Powerstroke Years to Avoid

If you’re in the market for a used 6.0 Powerstroke, there are certain years you should avoid. The 2003 and 2007 model years seem to be the most troublesome, with the highest number of complaints and issues reported. Both engine and transmission problems are common in these two years, so it’s best to steer clear if you can.

2004 and 2005 models are also known to have their fair share of issues, although not as many as the 2003 and 2007 models. 2006 seems to be the best year of the bunch, with relatively few complaints compared to other model years. Of course, every truck is different and will have its own unique set of problems, regardless of what year it is.

That’s why it’s always important to get a thorough inspection before buying any used vehicle. But if you’re looking at 6.0 Powerstrokes specifically, try to avoid the 2003, 2004, 2005, and 2007 model years if possible.

7.3 Powerstroke Years to Avoid

If you’re in the market for a 7.3 Powerstroke, there are certain years you should avoid. The biggest problem with the 7.3 is the head gasket failure. This can happen as early as 100,000 miles, but is more common around 150,000-200,000 miles.

There are also issues with the EGR cooler and oil cooler leaking into the coolant system. These problems can be expensive to fix and can cause major engine damage if not addressed quickly. The best way to avoid these problems is to buy a 7.3 that has been well maintained and has had all of the necessary repairs done.

You can also have your mechanic check for any signs of head gasket or coolant system leaks before you purchase the vehicle. If you do end up buying a 7.3 that has these problems, make sure to get them fixed ASAP to prevent any further damage to your engine.

Most Reliable Ford Diesel Engine

Whether you need a workhorse of an engine for towing or hauling, or you just want something that will provide great fuel economy, the Powerstroke is a great option.


Diesel engines are known for their durability and longevity. However, there are certain years of Ford diesel engines that should be avoided. These years include the 6.9L engine from 1985-1987 and the 7.3L engine from 1994-1997.
