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 a proper antifreeze.
