Windshield Washer Fluid - GMC 1994 Sonoma Owner's Manual

Windshield Washer Fluid
To Add
Open the cap labeled
"WASHER FLUID
ONLY." Add washer
fluid until the bottle is
full.
NOTICE:
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 3/4 full when it's very cold.
This allows for expansion, which could damage the tank if it is
completely full.
Don't use radiator antifreeze in your windshield washer. It
can damage your washer system and paint.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the surface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
