Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to a
dealer for service. Have it repaired as soon as possible.
You may also have the fluid level checked by your
dealer when the oil is changed. SeeRecommended
Fluids and Lubricants
on page 7‑8for the proper fluid
to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives fluid from the brake master cylinder
reservoir.
See Brakes
on page 6‑30for more information.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.

{WARNING:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{WARNING:
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 fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
Notice: Using coolant other than DEX-COOL
®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 50 000 km (30,000 miles)
or 24 months, whichever occurs first. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL (silicate-free) coolant in the
vehicle.
6-23

Black plate (24,1)Chevrolet HHR Owner Manual - 2011
Engine Coolant
The cooling system in the vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for 5 years or 240 000 km
(150,000 mi), whichever occurs first.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a
problem with engine overheating, see Engine
Overheating on page 6‑28
What to Use
{WARNING:
Adding only plain water or some other liquid to the
cooling system can be dangerous. Plain water
and other liquids, can boil before the proper
coolant mixture will. The vehicle's coolant warning
system is set for the proper coolant mixture. With
plain water or the wrong mixture, the engine could
get too hot but you would not get the 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. Use a 50/50 mixture of clean, drinkable water and
DEX-COOL coolant. If using this mixture, nothing else
needs to be added. This mixture:
.Gives freezing protection down to
−34°F (−37°C),
outside temperature.
.Gives boiling protection up to 265°F (129°C),
engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine temperature.
Notice: If an improper coolant mixture is used, the
engine could overheat and be badly damaged. The
repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice: If extra inhibitors and/or additives are used
in the vehicle's cooling system, the vehicle could be
damaged. Use only the proper mixture of the engine
coolant listed in this manual for the cooling system.
See Recommended Fluids and Lubricants
on
page 7‑8for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
6-24

Black plate (25,1)Chevrolet HHR Owner Manual - 2011
The coolant recovery tank
cap has this symbol on it.
The tank is located in the
engine compartment
toward the front of the
engine on the
passenger's side of the
vehicle.
See Engine Compartment Overview
on page 6‑14for
more information on location.
Check to see if coolant is visible in the coolant recovery
tank. If the coolant inside the coolant recovery 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 mark, add a 50/50 mixture of
clean, drinkable water and DEX-COOL coolant at the
coolant recovery tank, but be sure the cooling system is
cool before this is done.
When the engine is cold, the coolant level should be at
the COLD FILL (A) line or a little higher. The COLD
FILL line is near the bottom of the tank and sticks out
from the rear of the tank.
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 in the cooling system.

How to Add Coolant to the Cooling
System
{WARNING:
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.
Notice: This vehicle has a specific coolant fill
procedure. Failure to follow this procedure could
cause the engine to overheat and be severely
damaged.
{WARNING:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{WARNING:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the surge tank
pressure cap —even a little —they can come out
at high speed. Never turn the cap when the
cooling system, including the surge tank pressure
cap, is hot. Wait for the cooling system and surge
tank pressure cap to cool if you ever have to turn
the pressure cap.
6-26

Black plate (27,1)Chevrolet HHR Owner Manual - 2011
If no coolant is visible in the coolant recovery tank, add
coolant at the pressure cap as follows:
1. Remove the pressurecap 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 there is still some pressure left to be
vented.
2. Then keep turning the pressure cap and remove it.
3. Add the proper DEX-COOL coolant mixture to the coolant fill port, up to the base of the port. See
Engine Coolant
on page 6‑24Engine Coolant for
more information about the proper coolant mixture. 4. Rinse or wipe any spilled coolant from the engine
and the compartment.
5. Then fill the coolant recovery tank to the COLDFILL (A) 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.
