Vehicles equipped with a 6.2L engine

WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. NOTE: For coolant flow diagrams, refer to ENGINE COOLING  in Description and Operation.

    Release the clamp and disconnect the heater inlet hose from the heater inlet tube.

  2. Fill the radiator through the radiator fill neck until engine coolant flows from the heater inlet tube.

    When adding or topping of the engine coolant:

    1. Measure the coolant concentration in the vehicle using the Coolant/Battery Refractometer 300-ROB75240 or equivalent.
    2. Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.
    3. Add/top off or adjust coolant as follows:
      • For concentrations measured 48/52 to 50/50 (equates to a freeze point between -31°C [-30°F] and -34°C [-37°F]), use Motorcraft® Orange Antifreeze/Coolant Prediluted to maintain a coolant concentration in this same range.
      • For all other concentrations, use Motorcraft® Orange Antifreeze/Coolant Concentrated and/or distilled water to get to the desired concentration.
      • 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.
    4. Recommended coolant concentration is 48/52 to 50/50 engine coolant to distilled water (freeze protection -31°C [-30°F] to -34°C [-37°F]).
    5. 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% decreases the overheat protection characteristics of the engine coolant and may damage the engine.
    6. 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 -26°C (-15°F).
      • Engine coolant concentration below 40% decreases the corrosion and freeze protection characteristics of the engine coolant and may damage the engine.
    7. Vehicles driven year-round in non-extreme climates should use a 48/52 to 50/50 mixture of engine coolant and distilled water (freeze protection -31°C [-30°F] to -34°C [-37°F]) for optimum cooling system and engine protection.
  3. Connect the heater inlet hose to the heater inlet tube and position the clamp.

    All vehicles 

  4. Fill the radiator through the radiator fill neck until the coolant level is at the bottom of the filler neck.

    When adding or topping of the engine coolant:

    1. Measure the coolant concentration in the vehicle using the Coolant/Battery Refractometer 300-ROB75240 or equivalent.
    2. Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.

      • Engine coolant concentration above 60% decreases the overheat protection characteristics of the engine coolant and may damage the engine.
    6. 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.

  5. Install the radiator cap.
  6. Fill the coolant expansion tank until the coolant reaches the COLD FILL mark.
  7. Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air at A/C vents in instrument panel.
  8. NOTE: If the air discharge remains cool and the engine coolant temperature gauge does not move, the engine coolant level is low in the engine and must be filled. Stop the engine, allow it to cool and fill the cooling system. Failure to follow this instruction may result in damage to the engine.

    Run the engine at idle until it reaches normal operating temperature.

  9. Turn the engine off and allow it to cool.
  10. Add the correct coolant mixture to the coolant expansion tank until the coolant level is at the COLD FILL mark.
  11. Start the engine and allow it to idle until it reaches normal operating temperature. While the engine is idling, feel for hot air from the A/C vents.
    • Hot air should discharge from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch.
  12. Check the engine coolant level in the coolant expansion tank and fill it as necessary.
  13. Repeat the previous 5 steps as necessary.
