In this guide, we will break down the specific Ford fluid requirements, explain the recent transition from Orange to Yellow coolant, and provide a step-by-step walkthrough for topping off your system safely.
By the end of this article, you will have the confidence to handle your own cooling system maintenance like a pro. We will cover the specific tools you need, common pitfalls to avoid, and how to spot the early warning signs of the dreaded coolant intrusion problem that affects many 1.5L and 2.0L engines.
Identifying the Correct 2018 ford escape coolant type for Your Engine
When the 2018 Ford Escape first rolled off the assembly line, it was filled with Motorcraft Orange Antifreeze/Coolant. This fluid meets the Ford specification WSS-M97B44-D and was the standard for years across the Ford lineup.
However, Ford has since superseded the Orange coolant with a newer, more robust formula known as Motorcraft Yellow. This newer fluid meets the WSS-M97B57-A1/A2 specification and offers better protection against corrosion and scaling within the cooling passages.
If you are shopping for the 2018 ford escape coolant type today, you will likely find that Motorcraft Yellow is the recommended replacement. It is backward compatible with the Orange fluid, meaning you can mix them if necessary, though a full flush is always the best practice for maximum protection.
The Difference Between Concentrated and Prediluted
When you arrive at the parts counter, you will have two choices: concentrated coolant or a 50/50 prediluted mix. The 50/50 mix is the most convenient for the average DIYer because it is ready to pour directly into the degas bottle without any extra steps.
If you choose the concentrated version, you must mix it with distilled water before adding it to your vehicle. Never use tap water, as the minerals in tap water can lead to calcium buildup and “clogging” of the narrow passages in your radiator and heater core.
For most weekend mechanics, the prediluted 2018 ford escape coolant type is the safer bet. It ensures the chemistry is perfectly balanced to provide freeze protection down to -34°F and boil-over protection up to 265°F.
Why the Switch from Orange to Yellow Matters
You might wonder why Ford moved away from the Orange coolant that served them for nearly a decade. The transition to Motorcraft Yellow was driven by the need for better long-term stability and improved protection for the aluminum components in modern EcoBoost engines.
The 2018 ford escape coolant type needs to handle high thermal loads, especially in the 1.5L and 2.0L turbocharged variants. The Yellow formula is an OAT (Organic Acid Technology) coolant that provides a longer service life and better resistance to “pitting” in the cylinder head.
If your Escape currently has Orange fluid that looks dark or murky, it is time for a change. Upgrading to the Yellow specification during your next service interval is one of the cheapest ways to extend the life of your cooling system gaskets and seals.
Compatibility and Mixing Fluids
While Ford states that Motorcraft Yellow is compatible with Orange, you should never mix either of these with the older “Gold” or “Green” coolants. Mixing different coolant technologies can cause the fluid to “gel,” which stops the flow of coolant and leads to engine overheating within miles.
If you are unsure what is currently in your reservoir, look at the color in the degas bottle. Orange will look bright orange or slightly pink, while Yellow has a distinct neon-yellow or gold hue. If the fluid looks brown or black, you have a contamination issue that needs immediate attention.
Always verify the WSS specification on the back of the bottle before pouring. Even “Universal” coolants from big-box stores should be used with caution; always ensure they explicitly list the 2018 ford escape coolant type compatibility on the label.
How to Safely Check and Top Off Your Coolant
Before you even touch the hood latch, there is one golden rule: Never open the cooling system while the engine is hot. The system is under significant pressure, and opening the cap can result in a geyser of scalding liquid that causes severe burns.
Wait at least an hour after driving before checking your levels. Park the vehicle on a level surface to ensure you get an accurate reading from the markings on the side of the coolant reservoir.
Locate the translucent plastic tank, often called the degas bottle, on the passenger side of the engine bay. You will see “MIN” and “MAX” lines molded into the plastic; your 2018 ford escape coolant type should fall right between these marks when the engine is cold.
Steps to Adding Coolant
- Slowly twist the pressure cap counter-clockwise. If you hear a hissing sound, stop and wait for the pressure to bleed off before continuing.
- Once the cap is removed, place a clean funnel into the opening to prevent spills on your serpentine belt or electrical connectors.
- Pour the 50/50 prediluted coolant into the tank until the level reaches the “MAX” line.
- Replace the cap and tighten it until it clicks or feels firmly seated. A loose cap will prevent the system from pressurizing, leading to overheating.
After topping off, start the engine and let it reach operating temperature while watching the temperature gauge on the dashboard. Keep an eye out for any leaks around the cap or the hoses connected to the reservoir.
Common Cooling System Issues in the 2018 Ford Escape
The 2018 model year is unfortunately known for a specific issue called coolant intrusion. This occurs when the engine block design allows coolant to leak into the combustion chambers, typically in the 1.5L and 2.0L EcoBoost engines.
If you find yourself constantly adding the 2018 ford escape coolant type but see no visible leaks on your driveway, you may be experiencing this problem. The coolant is being burned inside the engine, which can eventually ruin the spark plugs and the catalytic converter.
Early warning signs of intrusion include a “sweet” smelling white smoke from the exhaust, a rough idle upon cold starts (misfires), and a “low coolant” warning on the instrument cluster. If you notice these symptoms, take your vehicle to a certified technician for a pressure test immediately.
The Importance of the Degas Bottle Cap
A frequently overlooked component is the pressure cap on the degas bottle. This cap is designed to release pressure at a specific point (usually 21 PSI) to protect the radiator and hoses from bursting.
Over time, the rubber seals inside the cap can dry out or crack. If the cap fails to hold pressure, your 2018 ford escape coolant type will boil at a lower temperature, causing the engine to run hot even if the fluid level is correct.
Replacing the cap every 50,000 miles is a cheap “insurance policy” for your cooling system. It is a simple screw-on part that requires no tools but can save you from a major breakdown on a long road trip.
Tools and Materials for a DIY Coolant Flush
If you have decided to perform a full flush to switch to the newer Yellow 2018 ford escape coolant type, you will need a few basic tools. Having everything ready beforehand makes the job much smoother and prevents messy spills in your garage.
You will need a large drain pan (at least 2-gallon capacity), a set of pliers for the hose clamps, and a basic socket set. You should also have several gallons of distilled water on hand to rinse the system of old debris and chemistry.
Don’t forget safety gear. Nitrile gloves and safety glasses are essential, as engine coolant is toxic to humans and pets. Always clean up any spills immediately, as the sweet smell of antifreeze is unfortunately attractive to animals.
Required Items List:
- 2 Gallons of Motorcraft Yellow (Concentrated or Prediluted).
- 3 Gallons of Distilled Water (if using concentrate or for flushing).
- A spill-free funnel kit (highly recommended for bleeding air).
- A drain pan and old jugs for recycling the used fluid.
- Basic hand tools (10mm socket, pliers).
Using a spill-free funnel is a “pro tip” that makes the bleeding process much easier. These funnels attach directly to the reservoir and allow air bubbles to escape while keeping the system topped off with fluid.
Step-by-Step: Flushing the 2018 Ford Escape Cooling System
Start by ensuring the engine is completely cold. Locate the radiator petcock (drain plug) at the bottom of the radiator, usually on the driver’s side. Place your drain pan underneath and carefully loosen the plug to begin the draining process.
Once the initial flow stops, remove the degas bottle cap to allow air in, which will speed up the drainage. After the radiator is empty, close the petcock and fill the system with distilled water. Run the engine for 10 minutes with the heater on high to circulate the water through the heater core.
Repeat this drain-and-fill process until the water coming out of the radiator is clear. This ensures that all the old 2018 ford escape coolant type chemistry is gone, leaving a clean environment for the new Motorcraft Yellow fluid.
Refilling and Bleeding Air
Now, fill the reservoir with your new 50/50 mixture of Motorcraft Yellow. The most critical part of this job is “burping” the system. Air pockets trapped in the engine block can cause “hot spots,” leading to a warped cylinder head or a blown head gasket.
With the reservoir cap off, start the engine and let it idle. As the thermostat opens, you will see the coolant level in the tank drop suddenly. Add more fluid to keep it at the “MAX” line.
Squeeze the upper radiator hose gently to help push air bubbles toward the reservoir. Continue this process until the cooling fans kick on and you have steady heat coming from the interior vents. Once the level stabilizes, replace the cap and take a short test drive.
Maintenance Schedule for Long-Term Reliability
Ford typically recommends changing the coolant every 100,000 miles or 6 years, whichever comes first. However, many experienced mechanics suggest a 60,000-mile interval, especially if you live in a region with extreme temperatures or frequently tow a trailer.
Regularly inspecting your 2018 ford escape coolant type can tell you a lot about the health of your engine. Use a coolant refractometer or simple test strips to check the pH balance and freeze point of the fluid once a year.
If the fluid becomes too acidic, it will begin to eat away at the water pump impeller and the internal seals of the radiator. Prevention is significantly cheaper than replacing a $500 radiator or a $1,000 water pump.
Inspecting Hoses and Connections
While you are checking the fluid, take a moment to squeeze the rubber hoses. They should feel firm but pliable. If they feel “crunchy,” overly soft, or show visible cracks near the clamps, they are at risk of bursting under pressure.
Check the area around the water pump (located on the side of the engine) for any crusty orange or yellow residue. This residue is a sign of a slow leak that will eventually lead to a cooling system failure.
Maintaining the 2018 ford escape coolant type is about more than just the liquid; it is about the integrity of the entire sealed system. Catching a small leak now prevents a breakdown on the side of the highway later.
Frequently Asked Questions About 2018 ford escape coolant type
Can I use “All-Vehicle” green coolant in my 2018 Ford Escape?
No, you should avoid generic green coolants. These often use different chemical inhibitors that are not designed for the specific alloys in your Ford engine. Stick to the WSS-M97B57-A1/A2 (Yellow) or WSS-M97B44-D (Orange) specifications to ensure total compatibility and protection.
How much coolant does a 2018 Ford Escape hold?
The capacity varies slightly by engine. The 1.5L EcoBoost holds approximately 7.7 quarts, the 2.0L EcoBoost holds about 9.1 quarts, and the 2.5L iVCT engine holds roughly 9.4 quarts. Always buy at least two gallons of prediluted fluid to ensure you have enough for a full fill and top-off.
Is it normal for the coolant level to drop slightly over time?
A very slight drop over several months can be normal due to evaporation through the pressure cap. However, if you have to add fluid every few weeks, you have a leak. Check the degas bottle and radiator for cracks, or have a shop perform a “block test” to check for internal leaks.
What color should the coolant be in a 2018 Ford Escape?
From the factory, it was Orange. If it has been serviced recently by a dealer, it might be Yellow. If the fluid is clear, green, or blue, someone has used the wrong fluid, and you should consider a full system flush as soon as possible.
Final Thoughts on Cooling System Care
Taking care of your 2018 ford escape coolant type is one of the most effective ways to ensure your vehicle reaches the 200,000-mile mark. Whether you are sticking with the original Orange formula or upgrading to the superior Motorcraft Yellow, the key is consistency and cleanliness.
Remember to always use distilled water if you are mixing concentrate, and never open the system when it is hot. Keeping an eye on your reservoir levels during your monthly oil check can save you from the headache of a “coolant intrusion” repair or a roadside overheat.
Stay proactive with your maintenance, use the right parts, and your Ford Escape will continue to be a reliable partner for all your adventures. Stay safe and keep your engine cool!
