9.6.4.3 Checking the antifreeze compound
Fig.184: Check the antifreeze com-
pound
The antifreeze compound prevents the coolant from freezing at sub-zero
temperatures and protects the engine block and radiator from internal
corrosion. Under normal conditions an antifreeze compound content of
-20 °C to -30 °C is sufficient. The antifreeze concentration can be
checked with an antifreeze tester.

1) Use the 1:1 concentration for warm outside temperatures, too, to en-
sure protection against corrosion, cavitation, and deposits.
2) Do not mix the coolant with other coolants.
