Check the coolant level at regular intervals. If you look into
the radiator opening (Fig. 79) from above, the radiator fins
should be covered with coolant.
Make sure that enough antifreeze is always present in the
coolant, even in summer, as antifreeze also prevents internal
corrosion of the radiator and the engine.
Checking the antifreeze mix
Antifreeze prevents the coolant from freezing at tempera-
tures below zero and protects the engine block and the
radiator from internal corrosion. Under normal conditions,
the antifreeze concentration is sufficient for protection down
to between –20°C (–4°F) and –30°C (–22°F). You can deter-
mine the antifreeze concentration by using a conventional
antifreeze tester (Fig. 80).
