Engine Cooling System Draining, Filling and Bleeding: Filling
- Close the radiator drain valve.
- Install the front under body shield and the retainers.
- Install the under body shield and the retainers.
- Install the vacuum cooling system filler and follow the manufacturer's instructions to fill the system. Use the General Equipment: Cooling System Vacuum Tester and Refiller
-
NOTE: Follow these steps 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
- For concentrations measured 48/52 to 50/50 (equates to the temperature range shown), use the following coolant.
Material: Motorcraft® Orange Prediluted Antifreeze/Coolant / VC-3DIL-B (WSS-M97B44-D2)
Temperature: -30 - -34°F (-34.4 - -36.7°C)
- For all other concentrations, use the following coolant and/or distilled water to get to the desired concentration.
Material: Motorcraft® Orange Concentrated Antifreeze/Coolant / VC-3-B (WSS-M97B44-D)
-
- For extremely cold climates less than the following temperature:
Temperature: -34°F (-36.7°C)
- 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 the following temperature.
Temperature: -58°F (-50°C)
- Engine coolant concentrations above 60% decrease the overheat protection characteristics of the engine coolant and may damage the engine.
- For extremely cold climates less than the following temperature:
-
- 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.
- A coolant concentration of 40% provides freeze point protection down to the following temperature.
Temperature: -15°F (-26.1°C)
- Engine coolant concentrations below 40% decrease the freeze and corrosion protection characteristics of the engine coolant and may damage the engine.
- Vehicle driven year-round in non-extreme climates should use a 48/52 to 50/50 mixture of engine coolant and distilled water for optimum cooling system and engine protection.
