Adding
only plain water to your
cooling
system
can be
dangerous. Plain water, or some other
liquid like
alcohol, can boil
before the proper
coolant mixture will.
Your
vehicle’s
coolant
warning system
is set
for
the proper coolant
mixture. With plain
water
or the wrong
mixture,
your
engine
could
get
too
hot but you
wouldn’t
get the overheat warning. Your
engine
could
catch
fire
and
you
or
others could be burned.
Use
a
50/50
mixture
of
clean
water
and
DEX-COOL@
coolant.
I
NOTICE:
~
~
~
~
In
cold
weather, water can freeze and crack the
engine, radiator, heater core and
other
parts.
So
use the recommended
coolant.
