The 2015 Ford Edge uses a long-life, ethylene glycol–based coolant that meets Ford’s specific requirements. The recommended option is Motorcraft Premium Engine Coolant (50/50 premixed) or an OEM-approved equivalent that meets Ford specification WSS-M97B51-A2. Using coolant that isn’t Ford-approved can lead to improper cooling or corrosion over time.
Approved coolant options for the 2015 Edge
These options are compatible with the 2015 Edge when they meet Ford’s long-life OAT (organic acid technology) standard and Ford specification WSS-M97B51-A2.
- Motorcraft Premium Engine Coolant (50/50 premixed), ethylene glycol–based, long-life coolant that meets Ford WSS-M97B51-A2.
- Any OEM-approved long-life coolant that explicitly meets Ford specification WSS-M97B51-A2 and is compatible with Ford engines (ethylene glycol–based, OAT formulation).
- Ensure the coolant is not a conventional or silicate-based formulation and is clearly labeled as Ford/OEM-approved or meets Ford’s WSS-M97B51-A2 standard.
In practice, buying Motorcraft Premium Engine Coolant from a Ford dealer or a reputable parts retailer is the simplest way to ensure compatibility. Always confirm the product label matches Ford’s specification before purchasing or mixing with existing coolant.
Maintenance and replacement tips
Before performing a coolant replacement, prepare with these steps to ensure a safe and complete fill and proper air bleeding.
- Make sure the engine is completely cool before opening the cooling system to avoid burns from hot coolant or steam.
- Place a drainage pan under the radiator drain plug or petcock, then remove the drain to empty the system.
- Open the radiator cap (with caution) to relieve pressure, then drain the radiator and heater core as per service guidelines.
- Close the drains, refill with the correct coolant (preferably a 50/50 premixed Motorcraft coolant) to the proper level, and reinstall the cap.
- Run the engine with the radiator cap off until the thermostat opens and the coolant circulates; watch for air bubbles and top off as needed to maintain the proper level.
- Check for leaks around hoses, the radiator, and the water pump; properly dispose of used coolant at an approved facility and clean up any spills.
Following these steps helps prevent air locks and ensures the cooling system operates reliably with the correct long-life coolant.
Why the right coolant matters
Using the correct coolant is essential for preventing corrosion, maintaining proper heat transfer, and protecting the engine and cooling components. Ford–approved, ethylene glycol–based long-life coolant formulated to meet WSS-M97B51-A2 reduces the risk of seal damage, scale buildup, and overheating over the vehicle’s service life.
Summary
For a 2015 Ford Edge, use a long-life, ethylene glycol–based coolant that meets Ford specification WSS-M97B51-A2. The easiest option is Motorcraft Premium Engine Coolant (50/50 premixed) or any OEM-approved coolant that explicitly meets Ford’s spec. If replacing coolant, follow proper safety steps and disposal guidelines to maintain optimal cooling performance and engine longevity.
