 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	Remove coolant system reservoir end cover (1)
2	Check the cooling system coolant level in the reservoir (2)	 There is a maximum and minimum level indication on the cooling system reservoir.
3	Correct the coolant level, if necessary
Topical note	Notes on coolant		AH20.00-N-2080-01A
4	Correct the coolant level, if necessary	 Correct the coolant level, adding the recommended coolant, until reaching the cooling system's reservoir maximum level marking (Max.).
5	Carry out concentration correction, if necessary	Engine 924.999	AP20.00-B-2010-01A
