coolant GMC SAFARI 2003 Owner's Guide

Adding Washer Fluid
Open the cap with the
washer symbol on it. Add
washerfluid until the
tank is full.Notice:When using concentrated washeruid, follow the
manufacturer’s instructions for adding water.
Don’t mix water with ready-to-use washeruid.
Water can cause the solution to freeze and
damage your washeruid tank and other parts of
the washer system. Also, water doesn’t clean as
well as washeruid.
Fill your washeruid 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.
