Cooling system
The water pump in the engine ensures a forced circulation of the cooling
liquid. When the engine is cold, the cooling liquid only circulates in the
cylinders and cylinder heads. After the engine reaches the operating tempe-
rature (approx. 75°C, 167°F), the thermostat opens and the cooling liquid is
also pumped through the aluminum radiator.
Cooling is by means of the air stream. The lower the speed, the lower the
cooling effect. Soiled cooling fins also impair the cooling effect.
If, for example, slow urban traffic or waiting at a traffic light cause little or
no air to stream through the radiator, the temperature of the cooling liquid
will rise. The radiator fan
1
switches on when the cooling liquid reaches a
temperature of 102°C (216°F). Additional air is blown through the radiator
to prevent the cooling system from overheating.

XCESSIVE USE OF THE CLUTCH AT SLOW SPEED
A mixture of 40% antifreeze and 60% distilled water is used as the cooling
liquid. How-ever, the anti-freeze protection must be at least -25° C
(-13° F). Aside from antifreezing protection, this mixture also provides great
corrosion protection which is why it must not be replaced by pure water.

ORE ANTIFREEZE MUST BE ADDED IF YOU PLAN TO TRAVEL TO A REGION WHERE
TEMPERATURES ARE EXPECTED TO DROP BELOW
-25°C (-13°F).
Pressure induced by heating of the cooling liquid in the cooling system is
controlled by a valve in the radiator cap
4
; a water temperature rising up to
125° C (257° F) is admissible, without fear of problems.
Any excess cooling liquid caused by thermal expansion is conducted to the
compensating tank
5
. It will be sucked back in as soon as the temperature
in the cooling system drops.
Checking the cooling liquid level in the compensating tank
Check the level of the cooling liquid when the engine is cold. It should fall
between the MIN and MAX marks on the compensating tank
6
.
Add cooling liquid (see above for mixture ratio) if the cooling liquid level
drops below the MIN mark.
If you need to add cooling liquid quite often, the cooling system may leak.
If the compensating tank is empty, also check the cooling liquid level in the
radiator. Have the cooling system checked by an authorized KTM
workshop.
