WARNING:

The cooling system is under pressure when the engine is warm. There is a risk of scalding due to hot steam and hot coolant.

Scalding the skin and other parts of the body is possible.

  • Wear safety gloves.
  • Wear protective eyewear.
  • Reduce the pressure by covering the coolant expansion tank cap with a cloth and carefully opening it.

-- If necessary, fill the coolant again.
