Engine Cooling: Notes
NOTE:
The engine cooling system is filled with Motorcraft® Specialty Orange Engine Coolant. Mixing coolant types degrades the corrosion protection of Motorcraft® Specialty Orange Engine Coolant. Do not mix coolant types. Failure to follow this instruction may result in engine or cooling system damage.
NOTE:
Stop-leak style pellets/products must not be used as an additive in this engine cooling system. The addition of stop-leak style pellets/products can clog or damage the cooling system resulting in degraded cooling system performance and/or failure.
NOTE:
The addition of Cooling System Stop Leak Pellets darkens the coolant.
NOTE:
During normal vehicle operation, Motorcraft Specialty Orange Engine Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.
The cooling system consists of the:
- radiator.
- cooling fan motor and shroud.
- degas bottle.
- radiator drain valve.
- coolant pump.
- thermostat housing.
- block heater (if equipped).
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained 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 Motorcraft® Specialty Orange Engine Coolant. Do not mix coolant types. Mixing coolant types degrades the corrosion protection of the original coolant.
- Do not add alcohol, methanol, 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.
