It is essential that the cooling
system is always lled with the
coolant (e.g. ethylene glycol) inits relevant dilution as prescribed
by the engine manufacturer. Even
in regions with a mild climate
without frost, engine coolant
(so-called anti-freezer) must be
lled in. Adding coolants to the
cooling water raises the boiling
point of the cooling water and
prevents corrosion, lime deposits
and foaming inside the cooling
system. In addition, it contributes
towards reducing wear thanks to
its lubricating eects and, conse-
quently, to increasing the service
life of the coolant pump. Ethylene
glycol or other coolants should
not be lled in the cooling system
undiluted, since this may result in
a reduced cooling capacity in case
of overdosing.
