What is the service on a 100000 mile Ford f250?

At 100,000 miles, a Ford F-250 typically requires a major service that includes oil and filter changes, replacement of critical filters, fluid flushes, and comprehensive system inspections. The exact items depend on whether your truck runs on gasoline or diesel, as well as its model year and maintenance history.

In the sections below, we detail what to expect for gasoline-powered F-250s and diesel-powered F-250s at this milestone, including which fluids, filters, and components are commonly addressed, and why these services matter for long-term reliability and performance.

Gasoline-powered Ford F-250 at 100,000 miles

The following items are commonly addressed on gasoline-engine F-250 models reaching the 100,000-mile mark. The precise scope can vary by year and maintenance history.

• Engine oil and oil filter replacement


• Air filter replacement


• Spark plugs replacement (as recommended by Ford for gasoline engines)


• Cabin air filter replacement


• Transmission fluid and, if applicable, transmission filter service


• Coolant/antifreeze replacement or flush


• Differential fluids replacement (front and rear)


• Transfer case fluid replacement


• Serpentine belt inspection and replacement if worn


• Brake system inspection and service (pads/rotors and fluid as needed)


• Fuel system inspection and fuel filter replacement (if equipped for your model year)

These tasks help maintain power, efficiency, and braking performance, while reducing the risk of unexpected breakdowns as the truck ages. Always refer to your owner’s manual or your Ford dealer for the exact items and intervals for your specific year and trim.

Diesel-powered Ford F-250 (6.7L Power Stroke) at 100,000 miles

Diesel engines differ in their maintenance needs. At 100,000 miles, diesel F-250s typically emphasize the fuel system, cooling system, and drivetrain fluids, along with routine inspections. The following items are commonly addressed on diesel models at this milestone.

• Engine oil and oil filter replacement


• Diesel fuel filter replacement (and fuel system inspection)


• Air filter replacement


• Coolant/antifreeze replacement or coolant service


• Transmission fluid and, if applicable, transmission filter service


• Transfer case fluid replacement


• Axle/differential fluids replacement (front and rear)


• Def/DEF system check and refills as needed


• Glow plug diagnostics and replacement if required


• Serpentine belt inspection and replacement if worn


• Brake system inspection and service (pads/rotors and fluid as needed)

Diesel-specific maintenance, especially fuel filtration and DEF system checks, helps protect the fuel-injection system, exhaust aftertreatment, and overall reliability of the Power Stroke engine. As with gasoline models, consult your owner’s manual or dealer for precise intervals and any model-year caveats.

Maintenance notes and considerations

Beyond the lists above, a 100,000-mile service often includes a general multi-point inspection covering hoses, belts, cooling system components, battery and charging system, steering and suspension, tire condition, alignment, and overall vehicle electronics. Your technician may also recommend addressing tires, wheel bearings, or minor wear items that could become more costly if ignored.

Summary

Reaching 100,000 miles on a Ford F-250 marks a pivotal maintenance milestone. The core objective is to replace worn fluids and filters, verify the integrity of critical systems, and prevent failures that could lead to downtime. Whether your truck runs on gasoline or diesel, the exact service items and timing depend on engine type, year, and how well the vehicle has been maintained. Always follow the specific recommendations in your owner's manual and consult a trusted Ford service center to tailor the service to your truck’s history and usage.

What does Ford recommend for 100,000 mile service?

Replace the cabin air filter, ensuring that you have clean air and an HVAC system that works at its best. Inspect the accessory drive belt or belts, making sure that there are no signs of cracking or excessive wear. Replace the spark plugs to ensure that your engine continues to fire exactly when needed.

How much is Ford 100,000 mile service?

The cost for a Ford 100,000-mile service can range from approximately $500 to over $1,300, depending on the vehicle model, the specific services performed, and whether you use a dealership or an independent mechanic. The price is influenced by parts, labor rates, and the number of recommended procedures, which typically include replacing spark plugs, changing all fluids, and inspecting key components. 
Cost breakdown and factors

• Dealer vs. Independent: Dealerships often have higher labor rates and can be more expensive, but they may offer a more comprehensive service and use genuine Ford parts. 
• Vehicle Model: The cost can vary significantly based on the vehicle. For example, a 2019 Ford Expedition service was estimated around $926-$1280, while a 2017 Ford Expedition service came in at around $1600. 
• Specific Services: Key components that drive up the cost include spark plug replacement, which can be labor-intensive on some models, and the replacement of all fluids like transmission and coolant. 
• DIY Savings: You can save money by performing some of the simpler tasks yourself, such as changing the cabin air filter or replacing spark plugs.
