The 2017 Ford F-350 Super Duty can hold between 20.8 and 38.8 quarts (19.7 to 36.7 liters) of coolant, depending on the engine and cooling system configuration.
Quick Answer
- Total Cooling System Capacity: 20.8 to 38.8 quarts (19.7 to 36.7 liters)
- OEM Coolant Specification: Ford Motorcraft Orange Antifreeze/Coolant (VC-3-D or VC-3-D2), which is a Phosphate Hybrid Organic Acid Technology (P-HOAT) coolant meeting Ford specification WSS-M97B44-D.
- Mix Ratio: 50/50 mix of coolant and distilled water.
Capacity by Engine Option
| Engine | Capacity (Quarts) | Capacity (Liters) |
|---|---|---|
| 6.2L V8 Gas | 20.8 qt | 19.7 L |
| 6.7L Power Stroke Diesel (Single Radiator) | 35.1 qt | 33.2 L |
| 6.7L Power Stroke Diesel (Dual Radiator) | 38.8 qt | 36.7 L |
Flush Interval
- Normal Service: The initial flush is recommended at 200,000 miles or 10 years, whichever comes first. Subsequent flushes should be done every 100,000 miles or 5 years.
- Severe Duty: Under severe operating conditions (towing, heavy loads, extensive idling), it's recommended to change the coolant every 60,000 miles.
How to Refill & Bleed
Refilling the cooling system on the 2017 F-350, especially the 6.7L Power Stroke, requires careful attention to avoid air pockets.
- Mix Coolant: If using concentrate, mix it 50/50 with distilled water before adding.
- Slow Fill: Add the coolant mixture to the degas bottle (coolant reservoir) very slowly.
- Run Engine: Start the engine and let it warm up with the heater on high.
- Top Off: As the thermostat opens and coolant circulates, the level in the degas bottle will drop. Continue to top it off to the "MAX" line as the air purges.
- Vacuum-Fill Recommended: Due to the complexity of the 6.7L diesel's cooling system (which includes primary and secondary cooling systems), a vacuum-fill tool is highly recommended to ensure no air is trapped in the system. Trapped air can lead to overheating.
Common Cooling System Issues
- Leaking Radiators: The radiators, both primary and secondary on the 6.7L diesel, can be prone to leaks from the plastic end tanks.
- Degas Bottle Leaks: The coolant reservoir (degas bottle) can develop cracks and leak over time.
- Water Pump Failure: While not overly common, water pump failure is a potential issue to be aware of, especially at higher mileages.
