Checking the Antifreeze Level
Use only pure fresh water that is free from particles, sludge
and other impurities
NOTE
1. Pour a small amount of coolant into a container and check
that the coolant is pure and clear.
2. Change the coolant if it is contaminated or cloudy.
3. Measure the antifreeze content with one of the following
instruments:
The following rules apply to ethylene glycol-based coolant:
• The antifreeze content must be minimum 35 percent by
volume for corrosion protection to be sufficient.
• Fill with antifreeze if the antifreeze content is below 35
percent by volume.
• Antifreeze content greater than 60 percent by volume
impairs the ability to protect against frost.
• If ice forms in the coolant, there are disruptions initially, but
there is no immediate risk of damage. The engine should
not be subjected to heavy loads when ice starts to form.
Changing Coolant
Avoid spillage and use a suitable container. Used coolant
must be disposed of as specied in national and interna-
tional law.
