What engine is in a 2006 F-550?

The 2006 Ford F-550 most commonly used a 6.0-liter Power Stroke V8 turbo diesel; a gasoline alternative, the 6.8-liter Triton V10, was offered on select cab/chassis configurations.

In 2006, the F-550 sat at the top end of Ford’s F-Series heavy-duty lineup, built as a chassis cab for commercial use. Engine choices varied by GVWR, body style, and emissions package. The diesel 6.0L Power Stroke was the standard and most widely installed option, while a gasoline 6.8L V10 was available for specific configurations. Below is a breakdown of the engines you could encounter on a 2006 F-550.

Engine options for the 2006 F-550

Diesel option: 6.0L Power Stroke V8 Turbo Diesel

Before listing details, note that many 2006 F-550s came with Ford's 6.0L Power Stroke turbodiesel. Availability and exact output varied by emissions package and configuration.

Key characteristics of the diesel option commonly seen on the 2006 F-550 include:

• Engine: 6.0-liter Power Stroke V8 turbo diesel


• Configuration: designed for heavy-duty chassis cabs and vocational applications


• Performance notes: typically offered with a turbocharged setup and a torque-focused delivery suited to towing and haulage


• Transmission pairing: often matched with Ford's heavy-duty automatic transmissions of the era (e.g., TorqShift 5R110W variants)

Diesel variants were the workhorse choice for most 2006 F-550 buyers, especially in commercial and fleet use, due to higher torque and better long-haul durability for heavy loads.

Gasoline option details follow for those configurations that used a petrol engine.

Gasoline option: 6.8L Triton V10

Some cab/chassis configurations offered a gasoline alternative, the 6.8-liter Triton V10, for those who preferred or required a gasoline-powered setup.

Key characteristics of the gasoline option include:

• Engine: 6.8-liter Triton V10 gasoline


• Availability: offered on select 2006 F-550 configurations, less common than the diesel version


• Performance notes: horsepower and torque vary by emissions package and tuning; typical figures differ from the diesel option and are generally lower in torque compared to the diesel


• Usage context: often chosen for applications where diesel fueling or emissions considerations differ from the standard fleet setup

As with any used heavy-duty truck, verify the exact engine on a specific vehicle via the VIN, door sticker, or title to confirm which option it carries.

Summary

For the 2006 F-550, the dominant engine was Ford's 6.0L Power Stroke V8 turbodiesel, favored for its torque and towing capability in commercial use. A gasoline alternative, the 6.8L Triton V10, was available on certain configurations but was far less common. Always check the exact specification on a given unit to confirm the engine and related hardware, as options varied by GVWR, body style, and emissions package.

Is the 2006 6.0 Power Stroke a good engine?

The 2006 6.0L Powerstroke is not considered a good engine in stock form due to well-known issues like failing EGR coolers, head gasket failures, and oil cooler problems, according to Blessed Performance, Sinister Diesel, and Custom Offsets. However, it can become a reliable engine if these problems are addressed with "bulletproofing" upgrades, as it offers good power and is often priced lower than competitors, say Reddit users, SPEtuner, and this YouTube video.
 
Common issues and potential solutions

• EGR cooler failure: The original coolers are prone to cracking or sticking, leading to overheating and other issues. Upgraded or deleted EGR systems are common fixes. 
• Head gasket failure: The engine's design, with only five head bolts per cylinder, makes it susceptible to head gasket failure under high cylinder pressure. Many owners replace the stock head bolts with stronger aftermarket studs. 
• Oil cooler problems: The factory oil cooler can clog with debris or rupture, causing oil and coolant to mix. Clogged passageways also lead to high oil temperatures. Upgraded oil coolers are the standard solution. 
• High-pressure oil pump (HPOP) issues: Leaks can occur from the standpipe or dummy plug O-rings, causing a lack of high-pressure oil to the injectors and preventing the truck from running. These are relatively inexpensive to fix with new O-rings. 
• Turbocharger problems: While the 2006 model received some improvements, issues like an inadequate oil drain tube can lead to oil coking and turbo failure. 

What to look for in a 2006 6.0L

• Evidence of "bulletproofing": A truck that has already had the common failure points addressed with quality parts is a much safer buy. 
• Proper maintenance records: Even with upgrades, this engine requires diligent maintenance to stay reliable. 
• Stock or mild tuning: Trucks that have been heavily modified with aggressive tuning are more likely to have suffered from the design flaws. 

What year to avoid a 6.0 Power Stroke?

The 6.0L Powerstroke engine years to be most cautious about are 2003-2004, as these early models had the most significant issues with high-pressure oil pumps, injectors, and head gaskets. While all 6.0L engines (2003-2007) are known for common problems like issues with the EGR cooler, oil cooler, and head bolts, the later model years 2005-2007 are generally considered improved and more reliable due to factory upgrades. 
Years to be most cautious (avoid if possible) 

• 2003-2004: These are the most problematic years due to a less reliable High-Pressure Oil Pump (HPOP), faulty injectors, and a higher susceptibility to head gasket failure due to weaker head bolts. 

Years with factory improvements 

• 2005-2007: These years incorporated numerous factory updates, making them more reliable. Key improvements include an updated HPOP, upgraded head bolts (20mm vs. 18mm), and a better engine oil cooler design, though they can still experience issues, particularly with oil leaks from dummy plugs and standpipes. 

What to do if considering any 6.0L Powerstroke

• Look for "bulletproofed" trucks: A truck with all the common weak points addressed through aftermarket "bulletproofing" can be a great purchase. Be sure to ask for proof of the work performed. 
• Factor in repair costs: All 6.0L engines will likely require some repairs, so be prepared for potential costs for things like EGR and oil coolers, head studs, and turbo/HPOP issues, regardless of the model year. 

What motor comes in a F-550?

They'll tell you that the standard powertrain of the 2023 Ford F-550 is a 7.3-liter OHV PFI V8 engine that is capable of providing drivers with 225 horsepower and 468 lb-ft of torque, plus a 10-speed TorqShift® automatic transmission.
