How much coolant does a Ford F350 take?
The exact coolant capacity depends on the engine and year, but in general gasoline F-350s need about 15–18 quarts, while the 6.7L Power Stroke diesel uses around 34 quarts. For your specific truck, check the owner's manual or a Ford service bulletin to confirm.
Coolant capacity refers to the total amount required to fill the complete cooling system, including the radiator, engine block, heads, heater core, and related passages. Because the F-350 comes with different engines and configurations, the exact number can vary slightly by model year and market.
Coolant capacity by engine option
The following figures reflect typical official specifications for common F-350 configurations. Always verify the exact value for your year and engine in the owner's manual or Ford service data.
- 6.2L V8 gasoline: Approximately 16 quarts (about 15 liters) for the total cooling system.
- 7.3L Godzilla gasoline: Approximately 18 quarts (about 17 liters).
- 6.7L Power Stroke diesel: Approximately 34 quarts (about 32 liters).
Diesel engines generally require more coolant due to a larger cooling circuit and higher heat output.
Coolant type and filling guidance
To refill or top off, use Ford-approved coolant that meets the vehicle’s specifications. In most regions this is an ethylene glycol–based coolant offered by Motorcraft, either premixed (50/50) or as concentrate that you mix with distilled water. Do not mix different coolant chemistries or use water that contains minerals that can promote corrosion.
- Type and specification: Use Motorcraft or Ford-approved coolant that complies with the current Ford specification for your model year (often noted on the container or in the owner's manual).
- Mixture: Use premixed 50/50 coolant or mix concentrate with distilled water to achieve a 50/50 ratio.
- Filling and bleeding: With the engine cool, fill the reservoir to the indicated level. After starting the engine and warming it up, bleed air from the system as needed and top off to the proper level.
Bleeding procedures can vary by year and configuration, so consult the owner's manual or a service manual for exact steps. Using the correct coolant type and ensuring the system is properly bled helps prevent overheating and corrosion.
Summary
In short, the Ford F-350’s coolant capacity is engine-dependent: roughly 15–18 quarts for most gas engines and about 34 quarts for the 6.7L Power Stroke diesel. Always verify the exact capacity for your year and engine, and use Ford-approved coolant with proper mixing and bleeding procedures to maintain optimal cooling performance.
How much coolant is in a 6.7 powerstroke?
A 6.7L Powerstroke engine has a primary cooling system and a secondary cooling system, with a total capacity of approximately 47.3 to 50.2 quarts of coolant, depending on the model year. The primary system takes about 30 to 35.1 quarts, and the secondary system holds about 15.1 quarts.
Primary cooling system
- Capacity: 29.4-30.3 quarts (2011-2016) or 31.7-35.1 quarts (2017-2020), notes Hot Shot's Secret.
- Location: The main engine cooling system, located on the driver's side of the engine bay.
Secondary cooling system
- Capacity: 8.1 quarts (2011-2016) or 14.3 quarts (2017-2020), cites Ford's service content.
- Location: A separate system that cools the charge air cooler, EGR fuel cooler, and transmission cooler.
- Tank: The secondary tank is typically located on the back of the radiator.
How much coolant does a 350 engine hold?
Capacity should be around 4 gallons. 2 gallons of coolant and fill the rest with water if it is completely empty.
How much coolant does a 2004 Ford f350 hold?
The 2004 Ford F-350's coolant capacity depends on the engine: the 6.0L diesel has a capacity of approximately 27.5 quarts, while the 7.3L diesel is around 32.75 quarts. The 6.8L gasoline engine's capacity is 28.8 liters (30.4 quarts), which increases to 30.8 liters (32.5 quarts) if the truck has auxiliary rear heat.

This video demonstrates the process of flushing and refilling the coolant in a 6.0 Powerstroke engine: 44sAutomedic GarageYouTube · Jan 31, 2022
- 6.0L Powerstroke Diesel: Approximately 27.5 quarts (26.0 L)
- 7.3L Powerstroke Diesel: Approximately 32.75 quarts (31.0 L)
- 6.8L Gasoline V10: 28.8 liters (30.4 quarts)
- 6.8L Gasoline V10 (with auxiliary rear heat): 30.8 liters (32.5 quarts)
Important considerations
- Engine type: Always verify your F-350's engine type to ensure you use the correct capacity.
- Coolant additive: The 6.0L Powerstroke diesel specifically benefits from a Supplemental Coolant Additive (SCA), such as Motorcraft VC8, to recharge the system's protection.
- Flushing: It is crucial to perform a proper cooling system flush to remove old coolant and potential contaminants, especially with the 6.0L diesel, as it can be prone to overheating due to faulty components like the EGR cooler.
- Total capacity: Be aware that draining only the radiator will not remove all the old coolant. Residual coolant remains in the engine block and heater core, which is why a complete flush is important to achieve the full capacity when refilling.
How much coolant does a 2013 F350 6.7 take?
Coolant: 29.4-30.3 quarts for the 2011-2016 models and 31.7 -35.1 quarts for 2017-2020.
