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.
