2007 CHEVROLET SILVERADO washer fluid

Adding Washer Fluid
Your vehicle has a low washer uid message in
the DIC that comes on when the washer uid
is low. The message is displayed for 15 seconds
at the start of each ignition cycle. When the
WASHER FLUID LOW ADD FLUID message
displays, you will need to add washer uid to the
windshield washer uid reservoir.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 500
for 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 your 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 winheild washer system and
paint.

(k)Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and
condition. Check that the purge valve, if the vehicle
has one, works properly. Replace as needed.
(l)Extreme Duty Service: Change transfer case
uid if the vehicle is mainly driven off-road in
four-wheel drive, or is used for heavy trailer towing.
Farming, mining, forestry, and Department of
Natural Resources (DNR) vehicles meet this
denition.
(m)During any maintenance, if a power washer is
used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water can
overcome the seals and contaminate the transfer
case uid. Contaminated uid will decrease the life
of the transfer case and should be replaced.
(n)Vehicles with diesel engine or with GVWR
above 10,000 lbs (4 536 kg) only: Inspect shields
for damage or looseness. Adjust or replace as
required. This is a Noise Emission Control Service.
Applicable to vehicles sold in the United States
and recommended for vehicles sold in Canada.
(p)If you drive regularly under dusty conditions,
inspect the lter or change indicator (if equipped)
at each engine oil change.(q)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help
ensure the safety, dependability, and emission
