2024 Ford F-350 Super Duty Factory Maintenance Schedule

Quick reference

Maintaining your 2024 Ford F-350 Super Duty according to factory specifications is crucial for its longevity, performance, and resale value. This heavy-duty truck is engineered for demanding tasks, and adhering to a strict maintenance schedule will ensure it continues to operate at peak efficiency, whether you're hauling, towing, or navigating rough terrain.

The 2024 F-350 Super Duty offers a robust lineup of powertrains, including the 6.8L V8 gasoline engine, the 7.3L "Godzilla" V8 gasoline engine, and the 6.7L Power Stroke V8 turbo diesel engine, including the High Output variant. Each of these engines and their accompanying drivetrains have specific maintenance needs, and while many intervals are similar, some key differences exist, particularly concerning fuel filters and spark plugs.

Severe-duty schedule

Ford defines severe-duty conditions as operating in extreme temperatures (hot or cold), frequent short trips (less than 10 miles), heavy towing or hauling, extensive idling, dusty or off-road conditions, or sustained high-speed driving. If your 2024 F-350 Super Duty falls into any of these categories, you'll need to follow an accelerated maintenance schedule. The most critical change is often related to oil changes and fluid services.

• Oil and Filter Change: Every 5,000 miles or 6 months (whichever comes first), as opposed to the normal duty 7,500-10,000 miles. This is paramount for the health of both gasoline and diesel engines under stress.
• Engine and Cabin Air Filters: Inspect more frequently and replace as needed, potentially every 15,000 miles, especially in dusty environments.
• Fuel Filter (Diesel): Replace every 15,000-20,000 miles or more frequently, depending on fuel quality and operating conditions. Dirty fuel can quickly clog filters and lead to costly injector issues.
• Transmission Fluid Service: Recommended every 30,000-60,000 miles if consistently towing heavy loads or operating in extreme temperatures. This includes both the fluid and filter.
• Differential and Transfer Case Fluid Service: Consider servicing these components every 30,000-60,000 miles under severe conditions to ensure proper lubrication and prevent premature wear.
• Brake Fluid: Flushed every 30,000 miles or 3 years due to potential moisture absorption, which degrades performance and can lead to corrosion.

Known issues by mileage (This generation F-350 Super Duty - 2023+)

As the 2024 F-350 is part of the latest generation (introduced in 2023), long-term common issues are still emerging. However, based on early reports and trends from previous Super Duty generations, here are some areas to monitor:

• Early Mileage (5,000-30,000 miles): Generally, these trucks are robust from the factory. Focus on routine maintenance. Some owners report minor electronic glitches or software updates needed for infotainment systems or driver-assist features. Keep an eye on tire wear, especially with heavy loads, and ensure proper tire pressure.
• Mid Mileage (30,000-60,000 miles): This is when some wear items start to show their age. Brake components (pads and rotors) may need replacement depending on driving habits and load. Suspension components like ball joints and tie rod ends should be inspected, particularly if operated off-road or with consistent heavy loads. Diesel owners should be diligent with fuel filter changes to prevent fuel system issues. Consider differential fluid service around this time, especially if towing frequently.
• Higher Mileage (60,000-100,000 miles+): Beyond the 60,000-mile mark, issues can become more prevalent if maintenance has been neglected. For diesel models, monitoring the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system for clogs or issues is crucial. Transmission performance should be smooth; any hesitation or rough shifting warrants immediate inspection. Coolant system hoses and connections can degrade over time and should be inspected for leaks. Spark plugs, if applicable, are due for replacement, and ignoring this can lead to misfires and reduced fuel economy.

Estimated cost per service

Costs can vary significantly based on your location, dealership rates, independent shop rates, and whether you opt for genuine Ford parts or aftermarket equivalents. The following are general estimates:

• Oil and Filter Change: $100-$200 (gasoline), $150-$300 (diesel, due to higher oil capacity and specialized oil).
• Tire Rotation: $25-$50 (often included with oil changes at dealerships).
• Cabin Air Filter Replacement: $50-$100.
• Engine Air Filter Replacement: $60-$120 (can be higher for diesel due to larger filters).
• Fuel Filter Replacement (Diesel): $150-$300 (includes parts and labor, often requires two filters).
• Brake Fluid Flush: $150-$250.
• Coolant Flush: $200-$400.
• Transmission Fluid and Filter Service: $300-$700 (can be higher for advanced multi-speed transmissions in severe duty).
• Spark Plug Replacement (Gasoline): $300-$600 (V8 engines have many plugs, and some can be difficult to access).
• Differential Fluid Service: $150-$250 per differential.
• Transfer Case Fluid Service: $100-$200.
• Accessory Drive Belt Replacement: $150-$300.
• PCV Valve (Inspection/Replacement): $50-$150.

These are estimates, and combining services often leads to package discounts.

What you can DIY vs shop

Many maintenance tasks on the 2024 Ford F-350 Super Duty can be performed by a competent DIY mechanic, saving labor costs, provided you have the right tools and knowledge. However, some tasks are best left to a professional shop, especially given the size and complexity of this heavy-duty truck.

DIY-Friendly Tasks:

• Oil and Filter Change: Requires ramps or a jack, oil filter wrench, drain pan, and the correct oil and filter. Diesel models have higher oil capacities and filters that might be in less conventional locations.
• Tire Rotation: Requires a good jack, jack stands, and lug nut wrench. Torque wrenches are essential for proper lug nut tightening.
• Cabin Air Filter Replacement: Usually a straightforward process, often located behind the glove box.
• Engine Air Filter Replacement: Typically easy to access and replace in the airbox under the hood.
• Wiper Blade Replacement: Very simple task.
• Fluid Level Checks: Checking oil, coolant, brake fluid, power steering (if applicable), and washer fluid levels is easy.

Shop-Recommended Tasks:

• Fuel Filter Replacement (Diesel): While technically DIY-able, it can be messy, and proper bleeding of the fuel system is critical to avoid engine issues. Specialized tools may be required.
• Brake Fluid Flush: Requires specific equipment to properly bleed the brake lines and can be dangerous if not done correctly.
• Coolant Flush: Proper disposal of old coolant and ensuring all air is purged from the system is crucial. The cooling system can be complex.
• Transmission Fluid and Filter Service: This is a more involved procedure, requiring specific tools, knowledge of transmission types, and precise fluid level checks at specific temperatures. Incorrect service can lead to costly transmission damage.
• Spark Plug Replacement (Gasoline): While some plugs are accessible, others can be challenging on V8 engines. Improper removal or installation can damage threads or spark plug coils.
• Differential and Transfer Case Fluid Service: Requires specialized fluids and often a pump to refill. Proper torque specs for drain/fill plugs are important.
• Accessory Drive Belt Replacement: Can be tricky due to tight spaces and the need for proper belt tension. Can be a DIY job for experienced mechanics.
• Any diagnostic work: If you have a check engine light or performance issue, a professional shop with diagnostic equipment is highly recommended.

Always consult your owner's manual for precise instructions and specifications before attempting any maintenance. When in doubt, it's always safer to trust an ASE-certified technician.
