What
to
Use
Use a mixture of one-half
dean
water
(preferably
distilled) and one-half
DEX-COOL@
coolant which
won’t damage aluminum 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 mix
will.
Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, 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
50150
mix of clean
water and
DEX-COOL@
coolant.
NOTICE:
If
you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t
be
covered
by
your
warranty.
Too
much water in the mix 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.
