COOLING SYSTEM
WARNING !
Ethylene glycol can be fatal if ingested and can cause
skin irritation and eye damage.
NOTE !
The coolant should be changed when the cooling system
is cleaned: every 6,000 hours or at least every 5 years.
See the section Changing the coolant and cleaning the
cooling system.
The coolant has several characteristics which are
important for the operation of the cooling system:
• Corrosion protection.
• Antifreeze.
• Increases the boiling point.
Scania recommends that the coolant used is a mixture of
water with antifreeze and corrosion protection (ethylene
glycol). The coolant should always contain 35-55%
antifreeze and corrosion inhibitor by volume so that
the coolant has the correct properties for the cooling
system to work.
See the Fluids section for more informations.
