The 2004 Ford F-150 came with several engine options, but the 5.4L Triton V8 was the most popular choice. This naturally aspirated, overhead cam engine produces 300 horsepower and 365 lb-ft of torque. It features a 3-valve per cylinder design with variable cam timing on the intake side. The 5.4L uses a cast iron block with aluminum heads and was designed for heavy-duty truck applications. It’s capable of towing up to 9,900 pounds when properly equipped and provides good low-end torque for work applications.

The 2004 Ford F-150 shares many parts with the 2004-2008 F-150 generation, as Ford redesigned the truck in 2004. The 5.4L engine components are largely compatible across these years, though some sensors and accessories may vary. Body panels, interior components, and suspension parts generally interchange within this generation. Some drivetrain components may also fit 2004-2010 models, but the 2009-2010 trucks received updates that can affect compatibility. Always verify part numbers and specifications, as Ford made running changes throughout production that can affect fitment.

The 5.4L Triton V8 in the 2004 F-150 has mixed reliability. While the engine is generally robust and long-lasting with proper maintenance, it has several well-documented issues. The most serious is spark plug ejection due to inadequate thread engagement in the aluminum heads. Regular maintenance is crucial – change oil every 5,000 miles, replace spark plugs at recommended intervals using proper torque specifications, and address timing chain tensioner issues early. Despite these problems, many 5.4L engines exceed 200,000 miles when properly maintained and issues are addressed promptly.
