What
to
Use
Use
a
mixture
of
one-half
c'1e'~m
wter
(preferably
distilled) and one-half
DEX-COOL@
coolant
which
won't damage alu~ninum parts.
If
you
use
this
mixture,
you don't need
to
add anything else.
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.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core
and other parts.
If
you have
to
add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If
you use the proper coolant, you don't have to
add extra inhibitors
or
additives
which
claim to
improve the system. These can be harmful.
