NOTICE:
When adding coolant, it is important that you

What to Use

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 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.
