2007 CHEVROLET MONTE CARLO coolant level

How to Add Coolant to the Cooling
System
Notice:Your engine has a specic cooling
system drain and ll procedure. Failure
to follow this procedure could cause your
engine to overheat and be severely damaged.
If your engine’s cooling system needs to
be drained and re-lled, please see your dealer.
1. Remove the
pressure cap
when the cooling
system, including
the pressure
cap and upper
radiator hose is
no longer hot.
Turn the pressure cap slowly counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means that there is still some pressure left.
2. Then keep turning the pressure cap and
remove it.
{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
3. Fill the cooling system with the proper
DEX-COOL
®coolant mixture, up to the base
of the ller neck. SeeEngine Coolant on
page 320for more information about
the proper coolant mixture.
4. Rinse or wipe any spilled coolant from the
engine and the compartment.
5. Then ll the coolant recovery tank to the cold
ll line.
6. Install the coolant recovery tank cap and the
pressure cap. After a day or two of driving,
when the engine is cold, check the coolant
level in the recovery tank. If it is low, rell it to
the cold ll line.
If the coolant in the recovery tank is constantly
low, you should have a dealership service
department inspect the vehicle for leaks.

(f)Lubricate all key lock cylinders. Lubricate all
hinges and latches, including those for the
body doors, hood, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove
box door, console door, and any folding seat
hardware. 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.
(h)Change automatic transaxle uid and lter 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 320 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(j)Check throttle 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. Do not
lubricate accelerator or cruise control cables.
(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.
(m)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(n)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.

can cause damage to your engine not covered
by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 320for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in
the windshield washer uid reservoir and add the
proper uid if necessary.
At Least Once a Month
