Engine Cooling: Notes

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The engine cooling system is filled with Motorcraft® Orange Antifreeze/Coolant. Mixing coolant types degrades the corrosion protection of the coolant. Do not mix coolant types. Failure to follow these instructions may result in engine or cooling system damage.

NOTE: Always fill the cooling system with the manufacturer's specified coolant. If a non-specified coolant has been used the cooling system must be chemically flushed. Refer to COOLING SYSTEM FLUSHING . Failure to follow these instructions may damage the engine or cooling system.

NOTE: During normal vehicle operation, Motorcraft® Orange Antifreeze/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.

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.

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 or topping off the engine coolant:

measure the coolant concentration in the vehicle using Coolant/Battery Refractometer 300-ROB75240 or equivalent.
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:
1. for concentrations measured 48/52 to 50/50 (equates to a freeze point between -34°C (-30°F) and -37°C (-34°F)), use Motorcraft® Orange Antifreeze/Coolant Prediluted to maintain a coolant concentration in this same range.
2. for all other concentrations, use Motorcraft® Orange Antifreeze/Coolant Concentrated and/or distilled water to get to the desired concentration. Refer to COOLING SYSTEM DRAINING, FILLING AND BLEEDING .

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.

To maintain the integrity of the coolant and the cooling system:

add Motorcraft® Orange Antifreeze/Coolant or equivalent. Do not mix coolant types.
do not add or mix with any other type of engine coolant Mixing coolants may degrade the coolant's corrosion protection.
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 originally equipped with Motorcraft® Orange Antifreeze/Coolant since a Ford-approved recycling process is not yet available.

The cooling system components are the:

block heater (if equipped).
radiator.
bypass tube.
pressure relief cap.
degas bottle.
radiator draincock.
coolant pump.
Engine Coolant Temperature (ECT) indicator unit.
temperature control valve - 2.0L Gasoline Turbocharged Direct Injection (GTDI)
thermostat (cold side).
transmission fluid cooler/warmer - 2.0L GTDI
turbocharger - 2.0L GTDI
variable speed fan motor assembly.
Fan Control (FC) module.

The transmission fluid warmer is mounted on top of the transmission. Warm coolant flows to the transmission fluid cooler/warmer during transmission warm-up via the temperature control valve to warm the transmission fluid.
