For a 2018 Ford Edge, use Ford-approved coolant that meets the manufacturer’s specification. The two main options are Motorcraft Extended Life Coolant (ELC) or Motorcraft Premium Gold Engine Coolant, both designed to meet Ford performance requirements. Use premixed 50/50 coolant or concentrate as directed, and avoid mismatched or non-Ford coolants.
Understanding the coolant needs of the 2018 Edge helps protect its aluminum engine components and ensure reliable cooling in varied climates. Ford’s coolant specifications emphasize compatibility, anti-corrosion protection, and long service life. If you’re unsure which exact product your vehicle needs, consult the owner’s manual or contact a Ford dealer to confirm the correct specification (such as WSS-M97B44-D or its latest equivalent).
Recommended Coolants for the 2018 Edge
These options are commonly specified by Ford for the Edge and other modern models. Always verify the exact Ford specification on the product label or in the owner’s manual before purchase.
- Motorcraft Extended Life Coolant (ELC) — meets Ford specification WSS-M97B44-D; designed for Ford aluminum engines and longer service life. Available as premixed 50/50 or concentrate as directed by the label.
- Motorcraft Premium Gold Engine Coolant — also Ford-approved and capable of meeting the same or equivalent Ford specification; typically offered in premixed 50/50 form or concentrate.
When selecting coolant, remember: colors vary by product and brand, but the critical factor is that the coolant is Ford-approved and labeled to meet WSS-M97B44-D (or the current Ford specification). If in doubt, ask a dealer or check the vehicle’s manual for the exact specification.
Replacing or Topping Off the Coolant
Before you begin, confirm you’re using the correct Ford-approved coolant and whether you have premixed or concentrate. The steps below outline the general process for topping off or performing a drain-and-fill in a typical modern Ford vehicle.
- Ensure the engine is cool and the vehicle is on a level surface. Open the coolant reservoir cap slowly to relieve any residual pressure.
- If using premixed coolant, simply fill to the “Full” or “Max” line as indicated on the reservoir. If using concentrate, mix it with distilled water to the recommended 50/50 ratio per the product instructions before filling.
- Inspect for leaks around hoses, the reservoir, and the radiator. If you’re performing a full drain, locate the radiator drain valve or drain plug and safely drain the old coolant into an appropriate container.
- Refill the system with the prepared coolant. Begin with the reservoir and then, if required, the radiator cap area after you’ve filled the reservoir. Use a funnel to minimize spills.
- Start the engine and run with the heater on high after a brief idle to help purge air from the cooling system. Watch the temperature gauge and listen for any abnormal sounds.
- Shut off the engine once the thermostat opens and the temperature stabilizes. Recheck the coolant level when the engine is completely cold and top off if needed.
- Dispose of used coolant at an authorized recycling facility and clean any spills promptly. Do not pour coolant down the drain or onto the ground.
- Record the service in your maintenance log and, if possible, have the cooling system pressure tested to confirm there are no leaks and that the system holds pressure.
After the procedure, monitor the vehicle for normal operating temperature and check for any signs of leakage or overheating. If you notice persistent overheating or a drop in coolant level, consult a technician for a more thorough inspection.
Additional Considerations
Do not mix different coolant types or brands unless they are explicitly labeled Ford-approved and compatible. If you’re unsure about the current coolant in the system, it’s safer to perform a complete drain and replacement with a single Ford-approved coolant rather than a partial top-off with an unverified product. Always follow the vehicle’s manual for the recommended service intervals and handling precautions for coolant and the cooling system.
Summary
The 2018 Ford Edge benefits from Ford-approved coolant options such as Motorcraft Extended Life Coolant (ELC) or Motorcraft Premium Gold Engine Coolant, either premixed or concentrate. Ensure the coolant meets Ford specification (WSS-M97B44-D or equivalent), avoid mixing incompatible coolants, and follow proper drain-and-fill or top-off procedures. When in doubt, consult the owner’s manual or a Ford dealer to confirm the exact specification and service steps.
