Vehicle Care 9-25
When the engine is hot, the level
should be at the hot MAX level.
When the engine is cold, the fluid
level should be between MIN and
MAX on the dipstick.
What to Use
To determine what kind of fluid to
use, see Recommended Fluids and
Lubricants on page 10‑7. Always
use the proper fluid.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer instructions before
use. If operating the vehicle in an
area where the temperature can fall
below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview on
page 9‑6 for reservoir location.
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 the
washer fluid tank and other
parts of the washer system.
Also, water does not clean as
well as washer fluid.
. Fill the washer fluid tank only
three-quarters full when it is
very cold. This allows for
fluid expansion if freezing
occurs, which could damage
the tank if it is
completely full.
. Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
vehicle's windshield washer
system and paint.
