and a proper antifreeze at the coolant recovery tank. (See “Engine
Coolant” in the Index for more information about the proper coolant
mix.)

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

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 -nd
