Coolant Level - Yamaha RX10K Assembly Manual

COOLANT LEVEL

WARNING
D Do not remove the radiator cap when the
engine and radiator are hot. Scalding hot
fluid and steam may be blown out under
pressure, which could cause serious inju-
ry. When the engine has cooled, place a
thick rag or towel over the radiator cap,
slowly rotate the cap counterclockwise to
the detent. This procedure allows any re-
sidual pressure to escape. When the his-
sing sound has stopped, press down on
the cap while turning counterclockwise
and remove it.
D The cooling system must be bled of air if
the reservoir tank becomes empty, if air
can be seen in the cooling system, or if
there is a cooling system leak.
CAUTION:
Operating the engine with an improperly
bled cooling system can cause overheating
and severe engine damage.
