      1. Wear protective gloves.
      1. Be careful as the radiator hoses are hot.
      1. Keep your hands away from the radiator fan.
    2. Maintain the engine speed at 2,000 to 2,500 rpm.

    3. Squeeze the inlet and outlet radiator hoses several times by hand to bleed air from the system.

      NOTICE:
      When squeezing the radiator hoses:
      1. Wear protective gloves.
      1. Be careful as the radiator hoses are hot.
      1. Keep your hands away from the radiator fan.
