	Remove/install
	Risk of injury  to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning  from swallowing coolant.	Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses.	AS20.00-Z-0001-01A
1	Open 2-stage cap (2)	Rotate 2-stage cap (2) half a revolution in counterclockwise direction, release overpressure, then unscrew 2-stage cap (2).
2	Set heater control to maximum heat output
	Checking
3	Check coolant level, if required adjust correctly.	If antifreeze protection is insufficient, replace as a separate repair order: ↓ Drain/fill in coolant
