Problems on the Road
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

the radiator pressure cap, is hot.
Wait for the cooling system and
radiator pressure cap to cool
if you
ever have to turn the pressure cap.

Index
under Capacities and Specifications.

somewhere in the proper operating
range. Push the dipstick all the way
