	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
