KTM 990 - Manual (Page 74)

Bleeding the cooling system
Remove the 5 screws and the left cover [3], disconnect the flasher cable and tank
ventilation.
Remove the bleeder screw [4] on the left side of the radiator.
To be able to completely bleed the cooling system, raise the motorcycle approx. 50 cm in
the front.
Add cooling liquid until it runs out of the discharge opening without bubbles and immedi-
ately mount the screw to prevent more air from getting into the radiator.
Completely fill the radiator with cooling liquid.
Connect the flasher cable and tank ventilation. Mount the cover.
Take a short ride and check the cooling liquid level again.
