2007 CHEVROLET EQUINOX radiator cap

Checking Coolant
The surge tank is located on the driver’s side
of the engine compartment. SeeEngine
Compartment Overview on page 342for more
information on location.
{CAUTION:
Turning the surge tank pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. Never turn the surge
tank pressure cap — even a little — when
the engine and radiator are hot.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be
at the COLD FILL line. When your engine is warm,
the level should be at the COLD FILL line or a
little higher.

1. You can remove the
coolant surge tank
pressure cap
when the cooling
system, including
the coolant
surge tank pressure
cap and upper
radiator hose,
is no longer hot.
Turn the pressure cap slowly counterclockwise
about one-quarter of a turn. If you hear a
hiss, wait for that to stop. This will allow
any pressure still left to be vented out the
discharge hose.
2. Then keep turning the pressure cap slowly,
and remove it.3. Fill the coolant surge tank with the proper
DEX-COOL
®coolant mixture, to the
COLD FILL line.

4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fans.By this time, the coolant level inside the
coolant surge tank may be lower. If the level is
lower, add more of the proper DEX-COOL
®
coolant mixture to the coolant surge tank until
the level reaches the COLD FILL line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight.
6. After driving the vehicle, check the level in the
surge tank again when the cooling system
has cooled down.
If the coolant is not at the proper level, repeat
Steps 1 through 3 and reinstall the pressure cap.
If the coolant is not at the proper level when
the system cools down again, see your dealer.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake
parts, including calipers, parking brake, etc.
Check parking brake adjustment.
(b)Visually inspect front and rear suspension
and steering system for damaged, loose, or
missing parts, signs of wear. Visually check
constant velocity joints, rubber boots, and axle
seals for leaks.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.(e)Make sure the safety belt reminder light and
all your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for any
other loose or damaged safety belt system parts.
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 look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
(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)If you drive regularly under dusty conditions,
the lter may require replacement more often.
443

(h)Change automatic transaxle uid 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, ush, and rell cooling system.
This service can be complex; you should
have your dealer perform this service. See
Engine Coolant on page 352 for what to use.
Inspect hoses. Clean radiator, condenser,
pressure cap, and ller 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 have
high effort or excessive wear.(k)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked.
Add uid if needed.
(l)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(m)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
control performance of your vehicle. Your
GM Goodwrench
®dealer can assist you with
these checks and services.
Be sure any necessary repairs are completed
at once. Whenever any uids or lubricants
are added to your vehicle, make sure they are
the proper ones, as shown inRecommended
Fluids and Lubricants on page 448.
