CHECKING AND TOPPING UP
Check the coolant level and top up the
expansion tank with cold engine.
◆ Stop the engine and wait until it has cooled
down.
NOTE Position the vehicle on firm and flat
ground.
◆ Remove the front cover, see p. 50 (RE-
MOVING THE FRONT COVER).
◆ Make sure that the level of the fluid con-
tained in the expansion tank (2) is included
between the “MIN” and “MAX” marks.
MIN = minimum level.
MAX= maximum level.
WARNING
If not, proceed as follows:
Loosen the filling cap (1) without remov-
ing it (give it half turn anticlockwise).
Wait a few seconds in order to release any
residual pressure.
Unscrew and remove the cap (1).
The coolant is noxious: do not swallow
it; if the coolant gets in contact with the
skin or the eyes, it can cause serious irri-
tations.
Do not use your fingers or any other ob-
ject to check if there is enough coolant.
Do not put additives or other subtances
into the fluid.
If you use a funnel or other similar items,
make sure that they are perfectly clean.
While topping up, never exceed the
“MAX” level, otherwise the fluid will flow
out of the tank while the engine is run-
ning.
◆ Top up with coolant, see p. 77 (LUBRI-
CANT CHART) until reaching approx. the
“MAX” notch.
◆ Put back the filling cap (1).
In case of excessive consumption of cool-
ant and in case the tank remains empty,
make sure that there are no leaks in the
circuit. Have it repaired by an aprilia Of-
ficial Dealer.
◆ Put back the front cover, see p. 50
(REMOVING THE FRONT COVER).
