2011 HONDA CIVIC cooling

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.
If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.Make sure the engine and radiator
are cool.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.

Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.
The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Put the radiator cap back on, and
tighten it fully.
Remove the radiator cap by
pushing down and turning
counterclockwise.

Have your dealer replace the filter
when this service is indicated by a
maintenance message on the
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the f low f rom

becomeslessthanusual.

Fill the f uel tank.Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors. Leave one window open slightly (if
the vehicle is being stored
indoors).Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
Disconnect the battery. If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f an cycles twice).
Pref erably, do this once a month.
Wash and dry the exterior
completely.

carpeting, floor mats, etc., are
completely dry.
Leave the parking brake off. Put
the transmission in reverse
(manual) or Park (automatic).

Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon page ).
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
If the temperature gauge stays at
the red mark, turn of f the engine.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank (see page
). Add coolant if the level is
below the MIN mark. Start the engine, and set the
temperature control dial to
maximum heat. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower
bef ore checking the radiator.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see on page ). 7. 8. 9.
