4.

7. Use a hose to drain the coolant.
General Equipment: Fluid Container
Loosen: 4 turn(s)

8. Torque: 4 turn(s)

4. Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed the cooling system.
Special Tool(s): UVU550000 (Airlift Cooling Tester)

5.
1. Measure the coolant concentration in the vehicle.
Special Tool(s): ROB75240 (Coolant/Battery Refractometer (Fahrenheit))

2. Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.
3. Add/top off or adjust the coolant as follows:
- For concentrations measured 48/52 to 50/50 (freeze protection -31°C to -37°C [-30°F to -34°F]), use Motorcraft(R) Orange Antifreeze/Coolant Prediluted to maintain a coolant concentration in this same range.
Material: Motorcraft(R) Orange Antifreeze/Coolant Prediluted / VC-3DIL-B (WSS-M97B44-D2)

- For all other concentrations, use Motorcraft(R) Orange Antifreeze/Coolant Concentrated and/or distilled water to get to the desired concentration.
Material: Motorcraft(R) Orange Antifreeze/Coolant Concentrated / VC-3-B (WSS-M97B44-D)

- When refilling the engine coolant after a flush procedure, use a mixture of Motorcraft(R) Orange Antifreeze/Coolant Concentrated and distilled water to get to the desired concentration.

6. Recommended coolant concentration is 48/52 to 50/50 (freeze protection -31°C to -37°C [-30°F to -34°F]) engine coolant to distilled water.

7.
1. 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 point 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.
- Minimum coolant concentration is 40/60 for warm weather areas.
- Engine coolant concentration below 40% will decrease the corrosion and 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 -31°C to -37°C [-30°F to -34°F]) mixture of engine coolant and distilled water for optimum cooling system and engine protection.
