2022 Ford F-350 Super Duty: Coolant Capacity & Type

The 2022 Ford F-350 Super Duty utilizes a robust cooling system, and understanding its coolant capacity and type is crucial for proper maintenance. The total cooling system capacity for your 2022 Ford F-350 Super Duty varies by engine, but generally ranges from 21.8 to 32.5 quarts (20.6 to 30.7 liters).

Quick Answer

• Total Cooling System Capacity: 21.8 – 32.5 quarts (20.6 – 30.7 liters) (varies by engine)
• OEM Coolant Specification: Motorcraft Specialty Orange Concentrated Antifreeze/Coolant, meeting Ford Specification WSS-M97B44-D2 (P-OAT – Phosphated Organic Acid Technology)
• Mix Ratio: Typically 50/50 with distilled water for concentrate, or use pre-mixed 50/50 solution.

Capacity by Engine Option

The 2022 Ford F-350 Super Duty was available with several engine options, each having a slightly different cooling system capacity:

Always refer to your owner's manual for the most accurate and up-to-date information for your specific vehicle configuration.

Flush Interval

Maintaining the coolant flush interval is vital for the longevity of your cooling system components and overall engine health. Ford recommends the following intervals for your 2022 F-350 Super Duty:

• Normal Duty: Replace coolant every 6 years or 100,000 miles, whichever comes first.
• Severe Duty (e.g., heavy towing, frequent off-road use, extreme temperatures): Consider reducing the flush interval to every 3 years or 50,000 miles, whichever comes first. Consult your owner's manual for specific severe duty recommendations.

How to Refill & Bleed

Properly refilling and bleeding the cooling system after a flush or repair is critical to prevent air pockets, which can lead to overheating. Always allow the engine to cool completely before performing any cooling system work.

1. Drain System: With the engine cool, place a drain pan under the radiator. Open the radiator drain cock (petcock) and remove the radiator cap to allow the coolant to drain completely. For a full flush, you may need to drain from the engine block as well; consult your service manual.
2. Rinse (Optional but Recommended): Once drained, close the drain cock and fill the system with distilled water. Run the engine with the heater on high until it reaches operating temperature. Drain the distilled water. Repeat this process until the drained water is clear.
3. Refill: Close the radiator drain cock. Begin filling the system slowly through the degas bottle (coolant reservoir) with the specified Motorcraft Specialty Orange coolant (50/50 mix). Fill until the level reaches the "COLD FILL" mark.
4. Bleed Air (Gasoline Engines): Start the engine and run it with the heater on high. As the engine warms up, the thermostat will open, and the coolant level in the degas bottle may drop. Continue to add coolant to maintain the "COLD FILL" level. Gently squeeze the upper and lower radiator hoses to help expel air. Allow the engine to cycle through several cooling fan cycles. On some F-350 models, there may be a specific bleed screw on a coolant hose or housing; refer to your service manual.
5. Bleed Air (Diesel Engines): The 6.7L Power Stroke diesel engine often has a more complex bleeding procedure. It may utilize a vacuum-fill tool for best results to ensure all air is removed. If a vacuum filler is not available, careful manual bleeding is still possible. After filling, run the engine with the heater on high and monitor the degas bottle level, adding coolant as needed. Some diesel cooling systems can be slow to bleed all air, and it may take several drive cycles before the coolant level stabilizes. Always check the coolant level after the first few drive cycles and top off as necessary.
6. Final Check: Once the engine is cool, recheck the coolant level in the degas bottle and adjust if necessary.

Common Cooling System Issues for 2022 Ford F-350 Super Duty

While the 2022 F-350 Super Duty is a robust truck, certain cooling system issues can arise, particularly given the demands placed on these heavy-duty vehicles:

• Radiator Leaks: Radiators can develop leaks over time due to age, road debris, or fatigue from vibrations, especially in heavy-duty applications. Keep an eye out for coolant puddles under the front of the truck.
• Water Pump Failure: The water pump is a critical component that circulates coolant. Failure can manifest as leaks from the weep hole, bearing noise (whining or grinding), or engine overheating. This is more common at higher mileages.
• Degas Bottle Cracks/Leaks: The plastic degas bottle (coolant reservoir) can develop cracks due to heat cycles and age, leading to slow coolant leaks and loss of pressure in the system.
• Thermostat Issues: A stuck-open thermostat can lead to the engine running too cool, reducing efficiency, while a stuck-closed thermostat can cause rapid overheating. Both can trigger dashboard warning lights and potentially cause engine damage.
• Hose Leaks: Coolant hoses can degrade over time due to heat and pressure, leading to cracks, bulges, or leaks at connection points. Regular inspection of hoses is recommended.
• 6.7L Power Stroke Specific Issues: While improved over earlier generations, the 6.7L Power Stroke diesel engine can still experience issues such as clogged EGR (Exhaust Gas Recirculation) cooler, which is part of the cooling system, or issues with the secondary cooling system for the turbocharger and EGR.

Regular inspection of your cooling system, including coolant levels, hose condition, and radiator integrity, can help prevent significant problems. Always use the specified Motorcraft Specialty Orange coolant to avoid compatibility issues and potential damage to your cooling system components.
