Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
By this time, the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more of the proper
DEX-COOL@ coolant mixture
through the filler neck until the level reaches
the base
of the filler neck. 8.
Then replace the pressure cap. At any time during
this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure
the arrows on the pressure cap line up with the
vent tube.

When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
Don’t 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 doesn’t clean as
well as washer fluid.
Fill your washer fluid tank only three-quarters full
when it’s very cold. This allows for expansion
if
freezing occurs, which could damage the tank if it is completely full.
Don’t use engine coolant (antifreeze)
in your
windshield washer.
It can damage your washer
system and paint.
