2006 CHEVROLET HHR overheating

When the engine is cold, the coolant level should
be at or above the COLD FILL line. If it is not, you
may have a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere in the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive
the vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If
the engine is overheating, the fan should be running.
If it is not, your vehicle needs service.Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
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.
If you have not found a problem yet, but the coolant
level in the coolant recovery tank is below the COLD
FILL line, add a 50/50 mixture of clean, drinkable
water and DEX-COOL
®engine coolant at the coolant
recovery tank. SeeEngine Coolant on page 5-20
for more information.

Backglass Wiper Blade Replacement
1. Remove the protective cap from the wiper arm.
If the protective cap is not removed before lifting
the wiper arm, the wiper arm could be damaged.

into the service position.
3. Rotate the wiper blade, and pull down on it to
remove it from the wiper arm.
4. Install the new wiper blade, then set the wiper
arm back into its original position and replace
the protective cap.
Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your GM Warranty booklet for details. For additional
information refer to the tire manufacturer’s booklet
included with your vehicle.
{CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as a result of too much friction.
You could have an air-out and a serious
accident. SeeLoading Your Vehicle
on page 4-32.
Underinated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold. SeeInflation - Tire
Pressure on page 5-52.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your tread is badly worn, or if your tires
have been damaged, replace them.
