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 and/or distilled water to get to the desired concentration.
Material
: Motorcraft® Orange Antifreeze/Coolant Concentrated (U.S.) / VC-3-B (U.S.) (WSS-M97B44-D)
When refilling the engine coolant after a flush procedure, use a mixture of Motorcraft® Orange Antifreeze/Coolant Concentrated and distilled water to get to the desired concentration.
11. Close the radiator drain valve.
