NOTE: The cooling system is filled with Motorcraft® Orange Antifreeze/Coolant. Do not mix coolant types. Mixing coolant types degrades the corrosion protection of the coolant. Failure to follow these instructions may damage the engine or cooling system.
NOTE: Engine coolant provides boil protection, corrosion protection, freeze protection, and cooling efficiency 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.
NOTE: Add Motorcraft® Orange Antifreeze/Coolant or equivalent.
NOTE: Do not add or mix with any other type of engine coolant. Mixing coolants may degrade the coolant's corrosion protection.
NOTE: 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.
NOTE: Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles originally equipped with Motorcraft® Orange Antifreeze/Coolant since a Ford-approved recycling process is not yet available.
When adding or topping off the engine coolant:
Measure the coolant concentration in the vehicle.
Use Special Service Tool: ROB75240 Coolant/Battery Refractometer (Fahrenheit).
Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.
Add, top-off or adjust the coolant as follows:
For concentrations measured 48/52 to 50/50 (freeze protection -34°C to -37°C [-30°F to -34°F]) use Motorcraft® Orange Antifreeze/Coolant Prediluted to maintain a coolant concentration in this same range.
Material
: Motorcraft® Orange Antifreeze/Coolant Prediluted (U.S.) / VC-3DIL-B (U.S.) (WSS-M97B44-D2)
For all other concentrations, use Motorcraft® Orange Antifreeze/Coolant Concentrated
