General Procedures: Draining

  1. WARNING: Make sure to support the vehicle with axle stands.

    Raise and support the vehicle.

  2. WARNING:
    • Release the cooling system pressure by slowly turning the coolant expansion tank cap a quarter of a turn. Cover the expansion tank cap with a thick cloth to prevent the possibility of scalding. Failure to follow this

    • Once coolant is visible from the outlet, close the bleeding point.
  20. Switch off the engine and wait for a minimum of 1 minute.
  21. Set the heater controls to maximum.
    • Start and run the engine.
    • Hold the engine speed at 2000 RPM until the coolant level in the expansion tank drops.
  23. Increase the engine speed from idle to 3500 RPM until hot air is emitted from the front and rear face vents.
  24. Continue filling the cooling system expansion tank until the coolant level becomes static within the COLD FILL RANGE.
  25. Add coolant to the expansion tank until the coolant level is 40 mm (1.57 inch) above the COLD FILL RANGE upper mark.
  26. CAUTION: Correct installation of the coolant expansion tank cap can be obtained by tightening the cap until an audible click is heard.
    G11601042
  27. Run the at engine at idle, until hot air is emitted from the front and rear face vents.
  28. CAUTION: Switch off the engine and allow the coolant temperature to go cold.

    Switch the engine off and allow to cool.

  29. Install the coolant expansion tank.
  30. WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth.
    CAUTION: Since injury such as scalding could be caused by escaping steam or coolant, make sure the vehicle cooling system is cool prior to carrying out this procedure.

    Check and top up the coolant to the COLD FILL RANGE upper mark.

  31. Install the left headlamp.
