WARNING:
The cooling system is under pressure when the engine is warm. 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.
- When the engine is cold, the upper edge (= MAX mark) on the floater arm -1- must be flush with the opening -arrow- on the coolant expansion tank.
- When the engine is warm, the upper edge of the floater arm can be above the coolant expansion tank opening.
-- If necessary, fill with coolant again.
