Checking the cooling liquid level in the radiator
Hold the radiator cap [1] with a cloth, carefully turn in a counterclockwise direction and
remove. The radiator should be completely filled with cooling liquid; no air should be in the
radiator.
If any cooling liquid is missing, the cooling system is probably leaking. Have the cooling
system checked at an authorized KTM workshop.

If possible, check the cooling liquid level when the engine is cold. If you need to remove
the radiator cap when the engine is hot, hold the cap with a cloth and open slowly, allow-
ing any excess pressure to escape (danger of scalding).
– Accumulated soil and lime on the radiator cap will cause you to lose cooling liquid. Carefully
clean the radiator cap, gasket [2] and sealing area each time.
– If more than 1 liter of cooling liquid needs to be added, you will need to bleed the cool-
ing system.

Bleeding the cooling system
