Understanding Your 2016 Ford Explorer Coolant Type

The 2016 Ford Explorer, like many modern Ford vehicles, requires a specific type of coolant to function correctly. Using the wrong fluid can lead to serious issues, including corrosion of internal components, premature water pump failure, and blockages in your radiator and heater core. This isn’t just about color; it’s about chemical composition.

The Specific Coolant for Your 2016 Explorer

Ford specifies a particular coolant for the 2016 Explorer: Motorcraft Orange Antifreeze/Coolant, part number VC-3-B or VC-3-D. This is an Organic Acid Technology (OAT) formulation, specifically designed for extended life and protection of aluminum components common in modern engines. It’s pre-diluted to a 50/50 mix with distilled water, making it ready for immediate use.

Always double-check your owner’s manual for the most accurate and up-to-date specifications for your specific vehicle. Manuals are the ultimate authority.

Why the Right Coolant Matters So Much

The coolant in your engine does more than just prevent freezing and boiling. It contains special additives that protect against corrosion, lubricate the water pump, and prevent cavitation. Modern engines, with their intricate designs and various metals, are highly sensitive to these chemical compositions.

Using a conventional green or yellow coolant in an engine designed for OAT can lead to gelling, clogging, and rapid deterioration of seals and gaskets. This accelerates wear and can cause significant damage over time.

The Critical Role of Coolant in Engine Health

Your engine generates an immense amount of heat, and without a properly functioning cooling system, it would quickly overheat and seize. Coolant, a mixture of antifreeze and water, circulates through the engine block, cylinder head, and radiator to manage this heat.

Preventing Overheating and Freezing

The primary function of coolant is to maintain your engine within its optimal operating temperature range. It raises the boiling point of water to prevent overheating in hot conditions and lowers the freezing point to protect against freezing in cold climates. This dual protection is vital for year-round vehicle operation.

A properly mixed 50/50 coolant solution typically offers protection down to -34°F (-37°C) and raises the boiling point to around 223°F (106°C), depending on pressure.

Protecting Against Corrosion and Cavitation

Beyond temperature regulation, coolant contains corrosion inhibitors that prevent rust and scale buildup within the cooling system. This is especially important for protecting sensitive aluminum components and ensuring the longevity of your radiator, heater core, and water pump.

Cavitation, the formation and collapse of vapor bubbles, can erode metal surfaces, particularly around the water pump impeller. Coolant additives help prevent this destructive phenomenon.

Checking and Topping Off Your Explorer’s Coolant

Regularly checking your coolant level is a simple yet crucial maintenance task that can prevent major problems. It’s a quick inspection that any car owner or DIYer can perform.

Step-by-Step Coolant Level Check

1. Ensure the Engine is Cold: Always check coolant levels when the engine is completely cool. This prevents scalding from hot, pressurized coolant.
2. Locate the Coolant Reservoir: In your 2016 Ford Explorer, the coolant reservoir is a translucent plastic tank, usually located near the radiator or fender, marked with “MIN” and “MAX” lines. It will have a yellow or white cap.
3. Inspect the Level: Observe the coolant level relative to the “MIN” and “MAX” lines on the reservoir. The level should be between these marks.
4. Note the Color: The coolant should be orange. If it looks rusty, murky, or has particles, it might be time for a flush.

If you notice a consistently low coolant level, it could indicate a leak. Look for puddles under the vehicle or signs of seepage around hoses, the radiator, or the water pump.

Adding Coolant Safely

If the coolant level is below the “MIN” line, you’ll need to add more.

1. Use the Correct Coolant: Only use Motorcraft Orange Antifreeze/Coolant VC-3-B/D or an equivalent OAT orange coolant that meets Ford’s WSS-M97B44-D specification.
2. Open the Reservoir Cap: Slowly twist the cap counter-clockwise to relieve any residual pressure, then remove it.
3. Pour Slowly: Carefully pour the coolant into the reservoir until the level reaches the “MAX” line. Do not overfill.
4. Secure the Cap: Replace the cap and twist clockwise until it clicks or is snug.

When adding coolant, always wear gloves and eye protection. Coolant is toxic and should not come into contact with skin or be ingested.

Performing a Coolant Flush for Your 2016 Ford Explorer

A full coolant flush and replacement are necessary periodically to remove old, degraded coolant and refresh the corrosion inhibitors. Ford typically recommends a coolant flush every 100,000 miles or every five years, whichever comes first, but always refer to your owner’s manual.

Tools and Materials You’ll Need

• New Motorcraft Orange Antifreeze/Coolant (VC-3-B/D), typically 2-3 gallons for a full flush.
• Distilled water (several gallons for flushing).
• Drain pan (large enough to hold the entire cooling system capacity).
• Funnel.
• Pliers (for hose clamps).
• Wrench or socket (for drain plug, if applicable).
• Clean rags.
• Safety glasses and gloves.
• Hose (for rinsing).
• Coolant system pressure tester (optional, but recommended for checking for leaks).

Step-by-Step Coolant Flush Procedure

1. Preparation and Safety:
   • Park your Explorer on a level surface.
   • Ensure the engine is completely cold.
   • Place your drain pan beneath the radiator.
   • Wear safety glasses and gloves.

1. Drain the Old Coolant:
   • Locate the radiator drain plug (petcock) at the bottom of the radiator. It’s usually a plastic winged knob.
   • Slowly open the drain plug and allow the coolant to flow into the drain pan.
   • For a faster drain, you can also remove the radiator cap (when cold!) and the lower radiator hose (use pliers for the clamp). Be prepared for a rush of fluid.
   • Allow the system to drain completely.

1. Flush the System (Optional but Recommended):
   • Once drained, close the drain plug and reattach the lower radiator hose.
   • Fill the system with distilled water.
   • Start the engine with the heater on full blast and let it run for 10-15 minutes to circulate the water.
   • Drain the distilled water. Repeat this flushing process until the drained water runs clear. This ensures all old coolant and contaminants are removed.

1. Refill with New Coolant:
   • Close the drain plug and ensure all hoses are securely connected.
   • Using a funnel, slowly pour the new Motorcraft Orange coolant into the coolant reservoir until it reaches the “MAX” line.
   • Leave the reservoir cap off. Start the engine and let it run, allowing the coolant to circulate and burp out air bubbles. Squeeze the upper and lower radiator hoses gently to help release trapped air.
   • As the engine warms up and the thermostat opens, the coolant level in the reservoir will likely drop. Continue to top it off to the “MAX” line.
   • Once the engine is at operating temperature and no more bubbles are visible, replace the reservoir cap.

1. Final Checks:
   • Take your Explorer for a short drive.
   • After the engine cools down, recheck the coolant level and top off if necessary.
   • Keep an eye on your temperature gauge and check for any leaks around the radiator, hoses, or reservoir over the next few days.

Never dispose of used coolant down the drain. It is toxic and must be taken to a certified hazardous waste disposal facility or an automotive shop that recycles coolant. Protect our environment!
