2009 BUICK ENCLAVE coolant level

Adding Washer Fluid
When the windshield washer uid
reservoir is low, a WASHER FLUID
LOW ADD FLUID message will be
displayed on the Driver Information
Center (DIC). SeeDIC Warnings and
Messages on page 3-48for more
information.
Open the cap with the washer
symbol on it. Add washer uid until
the tank is full. SeeEngine
Compartment Overview on
page 5-10for reservoir location.Notice:When using concentrated
washer uid, follow the
manufacturer’s instructions
for adding water.
Do not mix water with
ready-to-use washer uid.
Water can cause the solution to
freeze and damage your washer
uid tank and other parts of the
washer system. Also, water
does not clean as well as
washer uid.
Fill the washer uid tank only
three-quarters full when it is
very cold. This allows for uid
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 the
vehicle’s windshield washer
system and paint.
Brakes
Brake Fluid
The brake master cylinder reservoir
is lled with DOT-3 brake uid. See
Engine Compartment Overview on
page 5-10for the location of the
reservoir.
There are only two reasons why the
brake uid level in the reservoir
might go down:
The brake uid level goes down
because of normal brake lining
wear. When new linings are
installed, the uid level goes
back up.

6-4 Maintenance Schedule

If you see anything that might keep
a safety belt system from doing
its job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Checking the Restraint
Systems on page 1-58.
(f)Lubricate all key lock cylinders,
hood latch assemblies, secondary
latches, pivots, spring anchor
and release pawl, hood and door
hinges, rear folding seats, and
liftgate hinges. More frequent
lubrication may be required when
exposed to a corrosive environment.
Applying silicone grease on
weatherstrips with a clean cloth will
make them last longer, seal
better, and not stick or squeak.
(g)A fluid loss in any vehicle system
could indicate a problem. Have
the system inspected and repaired
and the fluid level checked. Add
fluid if needed.(h)Change automatic transmission
fluid if the vehicle is mainly
driven under one or more of these
conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-17 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.
(j)Check system for interference or
binding and for damaged or missing
parts. Replace parts as needed.
Replace any components that havehigh effort or excessive wear. Do not
lubricate accelerator or cruise control
cables.
(k)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
(l)If driving regularly under dusty
conditions, inspect the filter at each
engine oil change.
(m)Change transfer case fluid if the
vehicle is mainly driven under
one or more of these conditions:
In heavy city traffic where
the outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
