Draining
- 1.WARNING: Before beginning any service procedure service information, refer to Safety Warnings in GENERAL INFORMATION . Failure to follow this instruction may result in serious personal injury.
Refer to: Engine Cooling System Health and Safety Precautions .
- 2.
With the vehicle in NEUTRAL, position it on a hoist. REFER to: Jacking and Lifting - Overview .
- 3.WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth.
Remove the pressure relief cap.
- 7.WARNING: Be prepared to collect escaping fluid.
Connect a hose to drain the coolant. Open the radiator drain valve and drain the engine coolant in a suitable, clean container.

Filling
- 5.
- Measure the coolant concentration in the vehicle.
- 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 Prediluted Antifreeze/Coolant / VC-3DIL-B (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 Concentrated Antifreeze/Coolant / VC-3-B (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.
- 6.
Recommended coolant concentration is 48/52 to 50/50 engine coolant to distilled water (freeze protection -34°C to -37°C [-30°F to -34°F]).
- 7.
- For extremely cold climates (less than -37°C [-34°F]):
- It may be necessary to increase the coolant concentration above 50%.
- NEVER increase the coolant concentration above 60%.
- Maximum coolant concentration is 60/40 for cold weather areas.
- A coolant concentration of 60% provides freeze protection down to -50°C (-58°F)
- Engine coolant concentration above 60% will decrease the overheat protection characteristics of the engine coolant and may damage the engine.
- 8.
- For extremely hot climates:
- It is still necessary to maintain the coolant concentration above 40%.
- NEVER decrease the coolant concentration below 40%.
- Minimum coolant concentration is 40/60 for warm weather areas.
- Engine coolant concentration below 40% will decrease the freeze protection characteristics of the engine coolant and may damage the engine.
- 9.
Vehicles driven year-round in non-extreme climates should use a 48/52 to 50/50 (freeze protection -34°C to -37°C [-30°F to -34°F]) mixture of engine coolant and distilled water for optimum cooling system and engine protection.
- 14.
Turn the engine off for and wait for 1 minute to purge any large air pockets from the cooling system.
- 15.WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.
Check the engine coolant level in degas bottle and if necessary fill to the top of the MAX FILL line on the degas bottle if the engine is warm or to the top of the MIN FILL LEVEL if the engine is cold.
- 16.
Start the engine and let it idle until the engine reaches normal operating temperature and the thermostat is fully open. A fully open thermostat is verified by the cooling fan cycling on at least once.
- 21.WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.
Check the engine coolant level in degas bottle and if necessary fill to the top of the MAX FILL line on the degas bottle.
