Cooling system Refilling coolant with coolant trolley This procedure applies when the cooling system has been drained and needs to be filled with a large amount of coolant. WARNING! Use protective gloves as coolant can cause irrita- tion if it comes in contact with the skin. Hot cool- ant can also cause scalding. IMPORTANT! When it is necessary to fill a large quantity of coolant, it must be pumped in from underneath. This is to ensure that air does not get into the cooling system, which can cause the coolant pump to overheat. IMPORTANT! Mix the coolant as specified under the section Coolant. IMPORTANT! Do not start the engine until the correct coolant level has been obtained.
If the engine is started with a coolant level that is too low, the coolant pump shaft seal may be damaged, which can re- sult in leaks. 00:23-02 en-GB 31 © Scania CV AB 2016, Sweden
