Checking And Topping Up; Topping Up; Coolant - APRILIA AREA 51 - 1998 Manual


Do not use the vehicle if the
coolant is below the minimum
prescribed level.

Remember: 1 mile = 1.6 km
1 km = 0.625 miles
Check the coolant level every 2000 km and
after long rides; change it every 2 years.

Have the coolant changed by an
Official Dealer.
The coolant is made up of 50% water and
50% antifreeze.
This mixture is ideal for most running tem-
peratures and ensures good protection
against corrosion.
It is advisable to keep the same mixture
also in the hot season, since in this way
losses due to evaporation are reduced and
it is not necessary to top up very frequent-
ly.
The mineral salt deposits left in the radiator
by evaporated water are thus reduced and
the efficiency of the cooling system re-
mains unchanged.
If the outdoor temperature is below 0°,
check the cooling circuit frequently and if
necessary increase the antifreeze concen-
tration (up to maximum 60%).
26 use and maintenance Area 51

Do not remove the expansion
tank cap when the engine is hot,
since the coolant is under pres-
sure and its temperature is high.
If it gets in contact with the skin or with
clothes it may cause severe burns
and/or damages.
The coolant is noxious:
DO NOT SWALLOW IT.
KEEP AWAY FROM CHILDREN.

CHECKING AND TOPPING UP

Proceed as follows:
Raise the saddle, see p. 21 (UNLOCK-
ING/LOCKING THE SADDLE).
Make sure that the coolant level in the
expansion tank is included between the
"MIN" and "MAX" marks, by checking
through the special slot (1) provided on
the bottom of the crash helmet / glove
compartment.
If the level is not included between the
"MIN" and "MAX" marks, provide for top-
ping up.

TOPPING UP


Proceed with care, releasing any
residual pressure that may be
present in the system.
Loosen the plug (2), by giving it about
half a turn.
Wait for a few seconds, in order to re-
lease any residual pressure that may be
present in the system.
Unscrew and remove the plug (2).
Top up until the fluid reaches approx. the
"MAX" notch.
Do not exceed this level, otherwise the
fluid will flow out of the tank when the en-
gine is running.
Put back the filling cap (2).

In case of excessive consump-
tion of coolant and in case the
expansion tank remains empty,
make sure that there are no leaks in the
circuit.
Have it repaired by an
Dealer.
