	Check
	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	Open cap of expansion reservoir
2	Check coolant level, adjust to correct level if necessary.	The coolant level is on the marking (arrow) when the coolant is cold. For coolant at operating temperature the coolant level is about 1 cm above the marking (arrow).
3	Inspect cooling system for leaks	Only if there is coolant loss and against a separate repair order.
	Inspect cooling system for leaks	Only engines 112.945, 113.962/982	AR20.00-P-1010HA
4	Inspect anticorrosion/antifreeze agent in coolant and coolant composition, adjust to correct level if necessary	Only use approved anticorrosion or antifreeze agents.	*BF20.00-P-1001-02K
