 Warning	Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.	Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
 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
	Check
1	Unscrew cap of expansion reservoir.	 See information from body manufacturer.
2	Check coolant level.	 Check and correct the coolant level only when the coolant temperature is between 0 °C and 20 °C. The cooling system is correctly filled when the coolant is visible in the filler neck. Check the corrosion and antifreeze protection before correcting the coolant level.
3	Check anticorrosion and antifreeze protection.	 Commercially available tools: Antifreeze tester.
		 Drain screw to engine radiator	*BA20.20-N-1001-02A
		If the anti-corrosion and antifreeze protection is insufficient
		
		Correct anti-corrosion and antifreeze protection subject to separate repair order.
		Correcting anticorrosion/antifreeze concentration	AP20.00-G-2010-01H
		 To do so, drain coolant from cooler drain screw if required.
		 For filling capacity, see information from body manufacturer.
4	Correct coolant level, to do so add coolant up to "MAX" marking.	 See information from body manufacturer.
5	Screw cap onto expansion reservoir.

 Engine radiator, coolant hoses, lines
