2014 Ford F-150 Coolant Capacity & Type

The 2014 Ford F-150 has a total cooling system capacity of 13.3 to 17.6 quarts (12.6 to 16.7 liters), depending on the engine.

Quick Answer

• Total Cooling System Capacity: 13.3 – 17.6 quarts (12.6 – 16.7 liters)
• OEM Coolant Specification: Ford Motorcraft Orange Antifreeze/Coolant (WSS-M97B44-D)
• Coolant Type: Organic Acid Technology (OAT)
• Color: Orange
• Mix Ratio: 50/50 with distilled water (pre-mixed or concentrate)

Capacity by Engine Option

The 2014 F-150 was available with four different engine options, each with a slightly different cooling system capacity.

It is critical to use the correct OEM-specified coolant to prevent corrosion and ensure proper cooling system performance. For all 2014 F-150 engines, the correct coolant is Motorcraft Orange Antifreeze/Coolant, which meets Ford's WSS-M97B44-D specification.

Flush Interval

Ford recommends the following coolant service intervals for the 2014 F-150:

• Normal Service: The initial flush is recommended at 100,000 miles or six years, whichever comes first.
• Subsequent Flushes: After the initial service, the coolant should be changed every 50,000 miles or three years.
• Severe Duty: For vehicles used for towing, heavy hauling, or extensive idling, it is wise to shorten this interval to every 60,000 miles.

How to Refill & Bleed

Properly refilling and bleeding the cooling system is crucial to avoid air pockets, which can cause overheating.

1. Mix Coolant: If using a concentrate, mix it 50/50 with distilled water in a clean container.
2. Slow Fill: Add the coolant mixture to the coolant reservoir (degas bottle) slowly. This allows air to escape as the system fills.
3. Start Engine: With the heater on the highest temperature setting and the fan on low, start the engine and let it warm up. This circulates coolant and helps purge remaining air.
4. Monitor Level: As the engine warms and the thermostat opens, the coolant level in the reservoir will drop. Continue to top it off to the "MAX" line as air bleeds out.
5. Check for Leaks: Once the engine reaches operating temperature and the level stabilizes, check all hoses and connections for leaks. Replace the reservoir cap.

Pro Tip: Some technicians prefer using a vacuum-fill tool on these trucks. This device pulls the entire cooling system into a deep vacuum to remove all air before introducing new coolant, making the process faster and ensuring no trapped air.

Common Cooling System Issues

The 2011-2014 F-150 generation is generally reliable, but a few cooling system issues are known to occur:

• Coolant Reservoir Leaks: The plastic degas bottle can develop hairline cracks over time, leading to slow coolant loss.
• Water Pump Failure: While not rampant, water pump failure can occur. Symptoms include a coolant leak from the front of the engine or a whining/grinding noise.
• EcoBoost Coolant Fittings: On 3.5L EcoBoost engines, specific coolant line fittings and connectors (especially those going to the turbochargers) can leak over time due to heat and vibration. These are often small leaks that are hard to spot initially.

Regularly checking your coolant level and inspecting for leaks can help you catch these issues early before they lead to bigger problems.
