Chevrolet 2007 Express Automobile User Manual


 
If you have not found a problem yet, but the
coolant level is not at the COLD FILL mark, add a
50/50 mixture of clean, drinkable water and
DEX-COOL
®
engine coolant at the coolant
recovery tank. See Engine Coolant on page 308
for more information.
{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 would
not 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 DEX-COOL
®
coolant.
Notice:
When using concentrated washer fluid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
fluid. Water can cause the solution to
freeze and damage your washer fluid tank
and other parts of the washer system.
Also, water does not clean as well
as washer fluid.
Fill your washer fluid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing
occurs, which could damage the tank if
it is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
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.
