Coolant Level Check; Replacement Of Coolant - Husqvarna TC 450 Workshop Manual

Coolant level check

Check level (1) in right-hand radiator when engine is cold (place the motorcycle
so that it is perpendicular to the ground). The coolant should be approximately
10 mm above cells and besides, on TE and SMR models, it doesn't exceed the
middle of the expansion tank (2) located in front of the rear shock absorber.
The radiator cap (3) is provided of two unlocking positions, the first being for the
previous pressure discharge in the cooling system.
: Avoid removing radiator cap when engine is hot, as coolant may spout
out and cause scalding.
TE-SMR: Since the cooling fan (A) can be activated even when the start
switch is in OFF position, always keep a safe distance from the fane vanes.
: Difficulties may arise in eliminating coolant from varnished surfaces.
If this occurs, wash off with water.

Replacement of coolant

Place a vessel on the R.H. side of the cylinder, under the coolant drain screw (3).
FIRST remove the screw (3) then SLOWLY open the R.H. radiator cap (4); slope
the motorcycle on the right side to drain the coolant easily in the vessel.
Reassemble the screw (3).
Pour the necessary quantity of coolant in the radiator then warm up the engine
in order to eliminate any possible air bubble. Periodically check the connecting
hoses (see "Periodical maintenance card" page B.4-B.7); this will avoid coolant
leakages and consequent engine seizure. If hoses (B) show cracks, swelling
or hardenings due to sheats desiccation, their replacement shall be advisable.
Check the correct tightening of the clamps (C).
