Checking the cooling liquid level in the radiator
For better access to the radiator cap
[1]
, move the tank towards the rear, as described in
the "Battery" section.
Hold the radiator cap 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).
– If more than 0.5 (0.13 USgal) liter of cooling liquid needs to be added, you will need
to bleed the cooling system.
– Only continue to drive if there is enough cooling liquid in the system. Contact an author-
ized KTM workshop to have the error eliminated. You will damage the engine if you con-
tinue to drive when the cooling liquid temperature warning lamp is on.
