Danger!	Risk of injury to skin and eyes suffering 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 bottles. Wear protective gloves, protective clothing and eye protection.	AS20.00-Z-0001-01A
	Notes on coolant	All engines	AH20.00-N-2080-01A
1	Inspect coolant level	Check and correct engine coolant level only when coolant temperature is below 50 °C.  Before adjusting correctly engine coolant level, check anticorrosion/antifreeze protection. The cooling system is correctly filled if the coolant level is between the minimum and maximum markings (arrows).
2	Take off cap (1)
3	Inspect anticorrosion/antifreeze protection	 Insufficient anticorrosion/antifreeze protection:	*WH58.30-Z-1001-25A
		Adjust to correct concentration anticorrosion/antifreeze protection (subject to separate repair order).	AP20.00-T-2010-01CA

		In the event of fluid loss which is not due to normal consumption
		Check cooling system for leaks (subject to separate repair order).	AP20.00-T-2050CA
4	Adjust coolant to correct level by pouring in coolant up to the maximum marking	Use only coolant of the specified composition.
