2004 HONDA CIVIC engine

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 pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise without pushing
down to the first stop. After the
pressure releases, push down on
the cap and turn it until it comes
off.
Start the engine and set the
temperature control dial to
maximum. 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.Put the radiator cap back on
tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
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.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

This light should never
come on when the engine is
running. If it starts f lashing
or stays on, the oil pressure has
dropped very low or lost pressure.
Serious engine damage is possible
and you should take immediate
action. Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within ten seconds, turn of f
the engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving.
(See on page
). If the charging system
indicator comes on brightly
when the engine is running,
the battery is not being charged.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.

If the indicator remains on, or the
f uel cap was not loose or missing,
have the vehicle checked by the
dealer as soon as possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.If your vehicle battery has been
disconnected or gone dead, these
codes are erased. If takes at least
three days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition to ON (II), without starting
the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks 5
times, the readiness codes are not
set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set.
Refer to State Emissions Testing for
more inf ormation (see page ).
If the indicator comes on
while driving, it means one
of the engine’s emission
control systems may have a problem.
Even though you may f eel no
dif f erence in your vehicle’s
perf ormance, continued operation
may cause serious damage.
If you have recently ref ueled your
vehicle, the indicator coming on
could be a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator turn of f
immediately; it takes at least three
days of normal driving. 205

There are three popular types of
prof essional towing equipment.
The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. Release the parking brake.
Shif t the transmission to Neutral.
Release the parking brake.
Start the engine.
ShifttoD,thentoN.
Turn of f the engine.
If your vehicle needs to be towed,
call a prof essional towing service or,
organization. Never tow your vehicle
behind another vehicle with just a
rope or chain. It is very dangerous.
The operator
loads your vehicle on the back of a
truck. The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
the cables lif t that end of the vehicle
of f the ground. Your vehicle’s sus-
pension and body can be seriously
damaged.
If your Honda cannot be transported
by f lat-bed, it should be towed by
wheel-lif t equipment with the f ront
wheels of f the ground. If , due to
damage, your vehicle must be towed
with the f ront wheels on the ground,
do the f ollowing:

NOTICE: Improper towing preparation
will damage the transmission. Follow
the above procedure exactly. If you
cannot shif t the transmission or start
the engine (automatic transmission),
your vehicle must be transported with
the f ront wheels of f the ground.

(VIN) is the 17-digit number your
Honda dealer uses to register your
vehicle f or warranty purposes. It is
also necessary f or licensing and

ÎThe United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page . As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The Onboard Ref ueling Vapor
Recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
In Canada, Honda vehicles comply
with the Canadian Motor Vehicle
Saf ety Standards (CMVSS) f or
Emissions valid at the time they are
manuf actured.
The burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx) and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas.
Your vehicle has a Positive
Crankcase Ventilation System. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The Positive Crank-
case Ventilation valve routes themfrom the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
