Cooling System 17 - KTM 890 DUKE R 2021 Owner's Manual

COOLING SYSTEM 17

17.1 Cooling system
1
Water pump in the engine ensures forced circulation of the
coolant.
The pressure resulting from the warming of the cooling system is
2
regulated by a valve in radiator cap . Heat expansion causes
3
excess coolant to flow into compensating tank . When the tem-
perature falls, this surplus coolant is sucked back into the cooling
system. This ensures that operating the vehicle at the specified
coolant temperature will not result in a risk of malfunctions.
115 °C (239 °F)

The coolant is cooled by the air stream and a radiator fan ,
which is activated at high temperature.
The lower the speed, the less the cooling effect. Dirty cooling fins
also reduce the cooling effect.
