2007 CHEVROLET HHR coolant temperature

{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.
Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
SeeEngine Compartment Overview on page 298
for more information on location.
Engine Overheating
You will nd a coolant temperature warning light
and a coolant temperature gage on your vehicle’s
instrument panel. SeeEngine Coolant
Temperature Warning Light on page 187and
Engine Coolant Temperature Gage on page 188
for more information.

If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Just
turn it off and get everyone away from the
vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned.
Stop your engine if it overheats, and get
out of the vehicle until the engine is cool.Notice:If your engine catches re because
you keep driving with no coolant, your vehicle
can be badly damaged. The costly repairs
would not be covered by your warranty.If No Steam Is Coming From
Your Engine
An engine coolant temperature warning can
indicate a serious problem. SeeEngine Coolant
Temperature Warning Light on page 187.
If you get an engine coolant temperature warning,
but see or hear no steam, the problem may not
be too serious. Sometimes the engine can
get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
310

If you get the engine coolant temperature warning
with no sign of steam, try this for a minute or so:
1. If you have an air conditioner and it is on,
turn it off.
2. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is safe to do
so, pull off the road, shift to PARK (P) or
NEUTRAL (N) and let the engine idle.
3. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not come
back on, you can drive normally.If the warning continues and you have not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get
service help right away.

5. Then ll the coolant recovery tank to the
COLD FILL line.
6. Put the cap back on the coolant recovery
tank, but leave the pressure cap off.
7. Start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fan.
8. By this time, the coolant level inside the
radiator ller port may be lower. If the
level is lower, add more of the proper
DEX-COOL
®coolant mixture through the ll
port until the level reaches the base of
the ll port.
9. Then replace the pressure cap. At any time
during this procedure, if coolant begins to
ow out of the ll port, reinstall the pressure
cap. Be sure the pressure cap is hand-tight
and fully seated.
10. When the engine has cooled, check the
coolant in the coolant recovery tank. The level
in the coolant recovery tank should be at
the COLD FILL line when the engine is cold.
Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure
to read the manufacturer’s instructions before

where the temperature may fall below freezing,
use a uid that has sufficient protection against
freezing.
Adding Washer Fluid

Engine Compartment
Overview on page 298
for reservoir location.

(h)Change automatic transaxle fluid and filter 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.

When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require

service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 306 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and filler neck. Pressure test the cooling
system and pressure cap.
(j)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.(k)If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
(l)If you drive regularly under dusty conditions,
the filter may require replacement more often.
(m)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
