Engine Cooling: Notes
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The engine cooling system is filled with Motorcraft® Specialty Green Engine Coolant. Do not mix coolant types. Mixing coolant types degrades the corrosion protection of the coolant. Failure to follow these instructions may result in engine or cooling system damage.
NOTE:
Genuine Motorcraft® Specialty Green Engine Coolant is very sensitive to light. Do NOT allow this product to be exposed to ANY LIGHT for more than a day or two. Extended light exposure causes this product to degrade.
The cooling system components are the:
- block heater (if equipped).
- radiator.
- bypass tube.
- pressure relief cap.
- degas bottle.
- radiator draincock.
- coolant pump.
- thermostat housing.
- auxiliary coolant flow pump, refer to CLIMATE CONTROL -- FUSION, MILAN & MKZ article for removal and installation and CLIMATE CONTROL SYSTEM - GENERAL INFORMATION & DIAGNOSTICS -- FUSION, MILAN & MKZ (HYBRID) article for diagnostics.
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, maintain the engine coolant at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of engine coolant and distilled water. A coolant concentration of 50% provides freeze point protection down to -37°C (-34°F).
To maintain the integrity of the coolant and the cooling system:
- add the correct coolant type to the engine cooling system. The engine cooling system is filled with Motorcraft® Specialty Green Engine Coolant. Mixing different coolant types degrades the corrosion protection of the original coolant. Do not mix any type of coolants.
- do not add alcohol, methanol or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
- Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles.
