How to Add Coolant to the Coolant

Recovery Tank

If you haven't found a problem yet, but the coolant level
isn't at the FULL mark, add a 50/50 mixture of clean,
drinkable water and a proper coolant at the coolant
recovery tank. See "Engine Coolant" in the Index for
more information about the proper coolant mixture.
CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid such as 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, drinkable water
and a proper coolant.

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
