How much coolant does a Ford Flex hold?

The Ford Flex, a popular mid-size crossover SUV, holds approximately 13.7 quarts or 13 liters of engine coolant. This coolant, also known as antifreeze, is essential for maintaining the proper operating temperature of the vehicle's engine and preventing overheating.


Understanding the Ford Flex Cooling System


The Ford Flex is equipped with a liquid-cooled engine, which means that the engine's heat is transferred to a coolant fluid that circulates through the engine block and cylinder heads. This coolant then passes through the radiator, where it is cooled by the airflow generated by the vehicle's movement or the radiator fan. The cooled coolant is then recirculated back to the engine, creating a continuous cooling cycle.


The amount of coolant required for the Ford Flex's cooling system is determined by the size and design of the engine, as well as the overall size of the cooling system components, such as the radiator, hoses, and water pump.


Maintaining the Coolant Level



  • The recommended coolant capacity for a Ford Flex is 13.7 quarts or 13 liters.

  • It is important to regularly check the coolant level and top it up as needed to ensure the cooling system is functioning properly.

  • The coolant should be changed at the intervals specified in the Ford Flex's maintenance schedule, typically every 30,000 miles or 24 months.

  • Using the correct type of coolant, as recommended by Ford, is crucial to prevent damage to the cooling system components.


Maintaining the proper coolant level and condition is essential for the long-term health and performance of the Ford Flex's engine. Regular checks and timely coolant changes can help ensure your vehicle's cooling system operates efficiently and effectively.

What is the capacity of a coolant reservoir?


An average engine holds about 3 quarts (2 liters) of coolant, but this amount may vary depending on the vehicle's make, model, and type. For example, some Toyota models use only 1.5 quarts (1.5 liters), while others require 3 quarts (3 liters).



Why did Ford stop making Ford Flex?


Despite its strengths, the Flex faced increasing competition from other SUVs and crossovers in the market. The segment shifted towards a preference for sleeker, more car-like SUVs, and the Flex's wagon-inspired design fell out of favor.

How long will a Ford Flex engine last?


around 200,000 miles
How Many Miles Does the Ford Flex Last? How long do Ford Flexes last? Typically, you can expect a Ford Flex to last around 200,000 miles with excellent care, according to carparts.com. Making it to this age requires care and maintenance on your end, along with excellent driving.



How many quarts does a Ford Flex hold?


It's in the owners manual. Non-EcoBoost uses 5W20 (EB uses 5W30 BTW), same capacity both engines, 5.2L or 5.5 quarts.



Is coolant the same as antifreeze?


Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.



How many gallons of coolant do I need?


Let's consider an example: If the cooling system capacity of a vehicle is 12 gallons and the manufacturer recommends a 50/50 mix, you would need 6 gallons of antifreeze to fill the radiator. In this case, you would mix 3 gallons of antifreeze with 3 gallons of distilled water.
