What
to
Use
Use a mixture of one-half clean 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.
A
CAUTION:
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 50/50 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.
