If no coolant or the wrong coolant is used, liquid-cooled diesel
engines may be damaged by corrosion, cavitation and freezing.
Continually check the coolant level and the concentration of the cooling
system protecting agent in liquid-cooled diesel engines. Create the
necessary concentration of cooling system protecting agent by adding
a cooling system protecting agent to the cooling water. Check the
concentration of the cooling system protection agent with commercially
available test devices (e.g. gefo glycomat
®
).
The concentration of the cooling system protection agent in the
coolant must be as follows:
Crystallisation point Cooling system
protection agent
Water (distillate
or completely
demineralised)
–26 °C (–15 °F) 40 Vol.% 60 %
–37 °C (–34 °F) 50 Vol.% 50 %
–40 °C (–40 °F) 52 Vol.% 48 %
Wacker Neuson uses and recommends products that are free of nitrites,
amines, silicates and phosphates. These are listed in the "Overview of
service fluid specifications" section (see page 169). Wacker Neuson
supplies all the machines filled with a coolant mixture of 50 parts cooling
system protective agent and 50 parts water. This ensures frost protection
down to –37 °C (–34 °F).
