It is preferable to fill your engine with a 50% antifreeze-water mix-
ture.
This precludes the necessity of draining coolant in the winter.
Since most
antifreezes contain preservative agents
of one kind or
another, rusting within the engine is minimized.
Also, the antifreeze
mixture
boils
at
a
higher
temperature
than
water,
giving
cooling
system "head room".
