Warning (Continued)
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
Use a 50/50 mixture of clean drinkable
water and DEX-COOL coolant. This mixture:
.Gives freezing protection down to −37 °C
(−34 °F), outside temperature
.Gives boiling protection up to 129 °C
(265 °F), engine temperature
.Protects against rust and corrosion
.Will not damage aluminum parts
.Helps keep the proper engine
temperature
Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty.
Never dispose of engine coolant by putting
it in the trash, pouring it on the ground,
or into sewers, streams, or bodies of water. Have the coolant changed by an authorized
service center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The vehicle must be on a level surface when
checking the coolant level.
It is normal to see coolant moving in the
upper coolant hose return line when the
engine is running. It is also normal to see
bubbles entering the surge tank through the
small hose.
Check to see if coolant is visible in the
coolant surge tank. If the coolant inside the
coolant surge tank is boiling, do not do
anything else until it cools down.
If coolant is visible but the coolant level is
not at or above the cold fill line, add a
50/50 mixture of clean drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool before
this is done.
It is normal for the coolant level in the
bottom chamber to rise and fall with
operating temperature and ambient
conditions. Coolant will evaporate from the
bottom chamber in normal operation. This
will happen faster when the vehicle is driven
for long periods in hot, dry conditions.
If no coolant is visible in the coolant surge
tank, add coolant as follows:
How to Add Coolant to the Coolant
Surge Tank
If no problem is found, check to see if
coolant is visible in the coolant surge tank.
If coolant is visible but the coolant level is
not at the bottom of the fill neck, add a
50/50 mixture of clean, drinkable water and
DEX-COOL coolant at the coolant surge tank,

but be sure the cooling system, including
the coolant surge tank pressure cap, is cool
before you do it.
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
{Warning
Spilling coolant on hot engine parts can
burn you. Coolant contains ethylene
glycol and it will burn if the engine parts
are hot enough.
Caution
Failure to follow the specific coolant fill
procedure could cause the engine to
overheat and could cause system
damage. If coolant is not visible in the
surge tank, contact your dealer.
1. Remove the coolant surge tank pressurecap from the top chamber 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. 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. Keep turning the pressure cap slowly and remove it. Open the surge tank service
port cap to the lower chamber.3. Fill the surge tank top chamber with theproper mixture to the bottom of the fill
neck. The top chamber needs to be
completely full. Fill the surge tank
bottom chamber through the service port
to approximately half.

Vehicle Care 245
4. With the coolant surge tank pressure capoff and the surge tank service port cap
open, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the
coolant surge tank top chamber may be
lower. If the level is lower, add more of
the proper mixture to the surge tank top
chamber until the level reaches the
bottom of the fill neck.
5. Replace the surge tank pressure cap tightly and close the surge tank service
port cap.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Check the level in the surge tank top and
bottom chambers when the cooling system
has cooled down. If the coolant is not at the
proper levels, repeat Steps 1–3 and reinstall
the pressure cap and close the service port. If the coolant still is not at the proper levels
when the system cools down again, see
your dealer.
Engine Overheating
The vehicle has several indicators to warn of
the engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. See
Engine
Coolant Temperature Gauge 090. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hood
when this warning appears, get service help
right away. See Roadside Assistance Program
0 317.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, do not
continue to run the engine. Have the vehicle
serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
The hood extractor, if equipped, is
functional. It will allow water from rain and
car washes to enter the engine
compartment and contact hot surfaces.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16408685) - 2023 - CRC - 3/28/22
246 Vehicle Care
If steam is coming from the hood extractor
with no accompanying overheat warning, no
service is needed.
If No Steam Is Coming from the Engine
Compartment
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) for
an automatic transmission or Neutral for
a manual transmission, and let the
engine idle.
If the engine coolant temperature gauge is
no longer in the overheated area, the
vehicle can be driven. Continue to drive the vehicle slowly for about 10 minutes. Keep a
safe vehicle distance from the vehicle in
front. If the warning does not come back on,
continue to drive normally and have the
cooling system checked for proper fill and
function.
If the warning continues, pull over, stop, and
park the vehicle right away.
If there is no sign of steam, idle the engine
for three minutes while parked. If the
warning is still displayed, turn off the
engine until it cools down.Washer Fluid
What to Use
When windshield washer fluid is needed, be
sure to read the manufacturer's 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 reservoir is full.
See
Engine Compartment Overview 0231 for
reservoir location.
Caution
.Do not use washer fluid that contains
any type of water repellent coating.
This can cause the wiper blades to
chatter or skip.
.Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
.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.
