	Check
 Warning	Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. 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	Check the coolant level	 Access to carry out of the maintenance and repair works differs according to the body type/manufacturer Refer to the body makers instructions.
		Vehicles with expansion tank and level indicator:
		
		Vehicles without expansion tank
		
		Vehicles with expansion tank, without level indicator (MAX. and MIN.)
		
		Vehicles with level indication through a round visor.
