2016 Ford F-150 Coolant Capacity & Type

The 2016 Ford F-150 cooling system holds approximately 13.7 to 16.0 quarts (13.0 to 15.1 liters) of coolant, depending on the engine. This guide will detail everything you need to know about your truck's coolant.

Quick Answer

• Total Cooling System Capacity: 13.7 - 16.0 quarts (13.0 - 15.1 liters)
• OEM Coolant Spec: Ford Yellow Antifreeze/Coolant, P-OAT (Phosphated Organic Acid Technology) or HOAT (Hybrid Organic Acid Technology), meeting Ford Specification WSS-M97B57-A2 (Motorcraft Yellow Antifreeze/Coolant).
• Mix Ratio: 50/50 pre-diluted or 50% concentrate with 50% distilled water.

Capacity by Engine Option

Note: These capacities are for a complete drain and fill, including the overflow reservoir. Actual refill amounts may vary after a flush.

Flush Interval

Ford recommends a coolant flush and fill for the 2016 F-150 at the following intervals:

• Normal Duty: Every 100,000 miles or 6 years, whichever comes first.
• Severe Duty: More frequent changes may be necessary if your truck is regularly used for heavy towing, off-roading, or in extreme climates. Consult your owner's manual for specific severe-duty recommendations.

How to Refill & Bleed

Refilling and bleeding your 2016 F-150's cooling system properly is crucial to prevent air pockets, which can lead to overheating.

1. Safety First: Ensure the engine is cool before beginning any work on the cooling system. Wear appropriate personal protective equipment, including gloves and eye protection.
2. Drain the System: Locate and open the radiator drain petcock (usually on the bottom of the radiator). Remove the radiator cap to allow the system to drain completely. Some F-150 models may also have engine block drain plugs, which should be opened for a more thorough drain.
3. Flush (Optional but Recommended): If performing a flush, close the drain and fill with distilled water. Run the engine with the heater on high until it reaches operating temperature. Drain, and repeat until the drained water runs clear.
4. Refill: Close all drain points. Slowly add the Ford-specified 50/50 coolant mix to the radiator until it's full. Fill the overflow reservoir to the "COLD FILL" line.
5. Bleed the System: This is a critical step. Start the engine with the radiator cap off (or partially open to allow air to escape). Turn the heater to its maximum setting and fan speed. Allow the engine to reach operating temperature. As the engine warms up, air bubbles will rise and escape through the radiator opening. You may need to gently squeeze the upper and lower radiator hoses to help dislodge air pockets. There is no specific bleed screw on the 2016 F-150 coolant system; it is designed to self-bleed. Continue adding coolant as the level drops.
6. Monitor: Once the engine is at operating temperature and no more bubbles are visible, install the radiator cap. Drive the vehicle and monitor the temperature gauge closely. Check the coolant level in the overflow reservoir after the engine has cooled completely and top off as needed.

Common Cooling System Issues

The 2016 Ford F-150, like many vehicles, can experience several cooling system issues. Be aware of the following:

• Water Pump Leaks: The water pump is a common failure point. Signs include coolant leaks near the front of the engine, whining or grinding noises, or engine overheating.
• Coolant Leaks: Besides the water pump, leaks can occur from hoses, the radiator, the thermostat housing, or the degas bottle (coolant reservoir).
• Thermostat Failure: A stuck-open thermostat can cause the engine to run too cool, leading to poor fuel economy and reduced heater performance. A stuck-closed thermostat will cause rapid overheating.
• Overheating: This can be caused by low coolant levels, a failing water pump, a clogged radiator, a faulty thermostat, or a head gasket issue.
• Hose Degradation: Over time, radiator and heater hoses can become brittle, cracked, or soft, leading to leaks.
