In the 2006 model year, Ford released the Fusion as a new mid-sized sedan. In 2009, the Fusion came standard with a 2.3-litre in-line four-cylinder engine that produced 160 horsepower. The Fusion had an optional 221-horsepower, 3.0-litre V6 available, as well. A 50-50 mixture of water and gold-coloured antifreeze kept the Fusion's engine within a safe operating temperature. When refilling the Fusion's cooling system with coolant, it is important to follow a precise, yet simple, set of steps to prevent air from trapping in the system.
Turn the Fusion's engine off and allow it to cool, if needed.
Locate the coolant overflow bottle -- the translucent bottle on the passenger side of the engine compartment. Slowly loosen the coolant overflow bottle cap until you hear air escaping. Stop turning and allow all of the air to escape the system. Once the airflow stops, remove the cap completely.
Locate the coolant bleeder valve. On the 2.3-litre engine, the valve is located on the driver's side of the engine compartment, just behind the battery -- it's a long, vertical tube with a flathead screw on top. On the 3.0-litre engine, the valve attaches to the upper radiator hose -- it is a short tube with a flathead screw on top of it.
Open the coolant bleeder valve by loosening the screw on top with a flathead screwdriver.
Pour 50-50 premixed Motorcraft Premium Gold Engine Coolant, or an equivalent coolant meeting Ford specification WSS-M97B51-A1, into the coolant overflow bottle until the level is within the "Cold Fill Range" or reaches "Full Cold" line on the overflow bottle.
Close the bleeder valve, using a flathead screwdriver, and tighten the coolant overflow bottle cap.
Close the Fusion's bonnet.
Automotive coolant is highly toxic, so keep it away from children and animals.
