What is the 2018 Ford Explorer Coolant Capacity?

By Nick Marchenko, PhD

As a car enthusiast and a curious mind, I am constantly digging into the nitty-gritty details of various car models. One model that recently piqued my interest is the 2018 Ford Explorer, a reliable and robust SUV that has gained a substantial following. While the SUV's power and design are worthy of acclaim, understanding its technical specifications is equally crucial for any owner or enthusiast. Today, I am particularly keen on shedding light on the Explorer's engine coolant capacity, a critical factor in maintaining the vehicle's optimum performance.

It's easy to overlook coolant – until you find yourself stranded on the roadside with an overheated engine. Coolant, also known as antifreeze, is the lifeblood of your engine's cooling system. It keeps the engine from overheating in hot weather and freezing in the cold weather. The right quantity of coolant is a must, too little or too much can both lead to problems.

So, what is the coolant capacity for the 2018 Ford Explorer, particularly for the 3.5L EcoBoost™ engine? According to the service guide, the engine coolant capacity is 13.1 quarts or about 12.4 liters. This is the volume required to ensure optimal engine temperature regulation during operation.

Now, coolant is not a fill-it-and-forget-it thing. Regular checks are essential. Be sure to examine your coolant levels every time you pop open the hood for an oil check or before you embark on a long trip. If your coolant levels are consistently low, this may be an indication of a leak which can lead to engine damage.

Also, remember that the type of coolant you use matters. The 2018 Ford Explorer uses Motorcraft® Orange Antifreeze/Coolant Prediluted (Specification VC-3DIL-B for the U.S., CVC-3DIL-B for Canada, and VC-3DIL-B for Mexico) as per the specifications. This coolant meets the Ford specification WSS-M97B44-D2. This is essential information to keep in mind when you need to refill or replace your coolant.

Ignoring your engine's coolant can lead to several consequences such as engine damage, which may not be covered by your vehicle warranty, longer engine cranking periods, increased emission levels, reduced engine performance, and even poor fuel economy.

It's also important to note that Ford recommends not using supplemental engine oil additives as they are unnecessary and could lead to engine damage that may not be covered by your vehicle warranty. This points out that even as you strive to ensure that your engine is working optimally, it's crucial to use only recommended products.

In conclusion, understanding the coolant capacity of your vehicle, in this case, the 2018 Ford Explorer, is essential in ensuring your vehicle operates at its best. By maintaining the coolant level at the recommended 13.1 quarts and using the specified Motorcraft® Orange Antifreeze/Coolant Prediluted, you can keep your Explorer's engine running smoothly, efficiently, and most importantly, safely, for years to come. So next time you pop open your car's hood, give your coolant system a check – it deserves your attention.
