In order to ensure that the cooling circuit is fully
bled, when you are filling it with coolant, loosen the
screw located at the top of the cylinder head until
the air has been released, and retighten it. Then fill
the radia¬tor up to the correct level, not quite full,
so that the air acts as an expansion vessel.
Remove the cap on the top of the radiator to fill it up
with coolant, making sure you remove the air using
the bleed screw on the cylinder head. For optimum
functioning, do not fill the radiator right up to the
top. We recommend using a suitable filling recep-
tacle for greater control.
Avoid fill up at the top . It is recommend left a chamber
of air 8mm aproximately.
The factory-supplied coolant is a permanent-type anti-
freeze of ethylene glycol, diluted in 50% distilled water
and containing anticorrosive additives.
We recommend periodically bleeding the system
and changing the coolant. Watch out for abnormal
colour of the coolant: white stains (corroded alu-
minium), brown stains (corroded steel). To respect
the environment, dispose of the used coolant in
the designated places.
