Topping up the coolant
G
WARNING
The cooling system is pressurised when
the drive system is at normal operating
temperature. When you open the cap, you
could be scalded by hot coolant spraying
out. There is a risk of injury.
Let the drive system cool down before you
open the cap. Wear protective gloves and
eye protection when opening. Open the cap
slowly to relieve pressure.
!
Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g. on
the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point
of the coolant during operation is approx-
imately 130 †.
The antifreeze/corrosion inhibitor concen-
tration in the engine cooling system should
be between 40% and 50% (antifreeze protec-
tion down to -37 †). This will protect the
engine cooling system against freezing down
to approximately -25 †.
