The diluted coolant can attack the aluminum en-
gine parts. In an emergency, soft water alone can
be added. But the diluted coolant must be returned
to the correct mixture ratio within a few days.
If coolant must be added often or the reservoir tank
has run completely dry, there is probably leakage in
the cooling system. Check the system for leaks.
Coolant ruins painted surfaces. Immediately wash
