The 2012 Ford Fusion uses Motorcraft Premium Engine Coolant, an extended-life ethylene glycol coolant. In most cases, Ford recommends the 50/50 premixed formulation for ease of use and reliable protection.
Recommended coolant for the 2012 Fusion
Using the correct coolant is essential to protect the radiator, water pump, heater core, and cooling passages from corrosion and scale. Ford engines from this era require a long-life coolant that meets Ford's specifications. If you have a different coolant type on hand, do not mix it—flush and replace with Ford-approved coolant instead.
Below are the common options that meet Ford's guidance for this vehicle:
- Motorcraft Premium Engine Coolant, Extended Life (50/50 premixed)
- Motorcraft Premium Engine Coolant Concentrate (to be mixed 50/50 with distilled water)
When replacing coolant, use the Ford-recommended product to ensure compatibility with cooling system metals and seals, and to maintain the extended-life properties.
How to check or replace the coolant
If you are topping up or performing a drain and fill, follow these basic steps to ensure you do it safely and correctly:
Topping up vs. full drain and fill
Determine whether you just need a top-up or a full drain-and-fill based on the level, age of the coolant, and any signs of overheating or leaks.
- Make sure the engine is cool before opening the cooling system to avoid burns from hot coolant or steam.
- Locate the overflow reservoir; check the level on the "L" and "F" marks when the engine is cold.
- If topping up, use the correct Motorcraft coolant in the 50/50 premixed form, or mix the concentrate with distilled water to achieve a 50/50 ratio before pouring.
- Pour slowly to avoid air bubbles; fill to the "Full" line on the reservoir.
- Run the engine to operating temperature with the radiator cap off briefly to bleed air, then replace the cap once the level stabilizes.
- Check for leaks and recheck the level after the engine cools; top up if needed.
- Dispose of used coolant properly at a recycling facility.
Note: If you are unsure or uncomfortable performing a coolant service yourself, have a qualified mechanic perform the replacement. Using the correct coolant is essential for long-term cooling system health.
Summary
The 2012 Ford Fusion takes Motorcraft Premium Engine Coolant (extended-life), typically in a 50/50 premixed formulation. For best results, use Ford-approved coolant and follow proper maintenance steps, or consult a technician if in doubt.
