engine Acura RSX 2003 Repair Manual

A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently and have
the system inspected as soon as
possible.
Always use Honda Power Steering
Fluid. If it is not available, you may
use another power steering f luid as
an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
Check the level when the engine is
cold. Look at the side of the
reservoir. The f luid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
f luid to the UPPER LEVEL.

If spilled accidentally, wipe of f any
f luid completely.

To replace it:Loosen the f ive bolts.
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
f low. If you do not have access to
compressed air (such as a service
station), ask your Acura dealer to do
this service. The air cleaner element should be
cleaned or replaced according to the
time and distance recommendations
in the maintenance schedule.
Unsnap the clamp, then remove
the intake air duct f rom the f ront
of the air cleaner housing.
Use a pair of pliers to slide back
the clamp on the breather tube
attached to the side of the housing.

Tighten the spark plugs caref ully. A
spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage to
the threads in the cylinder head.

Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them.
Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.

The condenser and radiator f ins bend

or sof t-bristle brush to clean them.Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.

Block the rear wheels.
Fill the f uel tank.

If you need to park your car f or an
extended period (more than one
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 car back on the road. If
possible, store your car indoors.
If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the car is being stored indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or

To minimize sticking, apply a
silicone spray lubricant to all door
and hatch seals. Also, apply a body
wax to the painted surf aces that
mate with the door and hatch seals.If possible, run the engine f or a
while periodically (pref erably once
amonth).
If you store your car f or 12 months
or longer, have your Acura dealer
perf orm the inspections called f or in
the 24 months/30,000 miles (48,000
km) maintenance schedule (Normal
Conditions) as soon as you take it
out of storage (see page ). The
replacements called f or in the
maintenance schedule are not
needed unless the car has actually
reached that time or mileage. Coverthecarwitha‘‘breathable’’

material such as cotton.
Nonporous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.

When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things:
Diagnosing why your engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):
You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
Store the tool kit.
Store the wheel cover or center
cap in the cargo area. Make sure it
will not get scratched or damaged.
Reinstall the f loor mat and spare
tire cover, then close the hatch.
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or Neutral.
Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page .

Loose items can fly around the
interior in a crash and could
seriously injure the occupants.
Store the wheel, jack, and tools
securely before driving.

Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereisproba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (Seeon page .)
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the car from
a booster battery (see page ). In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page .
Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank. Are you using the proper starting
procedure? Ref er to on page .
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly. 280

To jump start your car, f ollow these
directions closely:
Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
Turn of f all the electrical acces-
sories: heater, A/C, stereo system,
lights, etc.
Put the transmission in Neutral or
Park, and set the parking brake. Connect one jumper cable to the
positive ( ) terminal on your
Acura’s battery. Connect the other
end to the positive ( ) terminal
on the booster battery.
If your car’s battery has run down,
you may be able to start the engine
by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.
You cannot start an Acura with an
automatic transmission by pushing
or pulling it. 1.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

µ
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.Once your car is running, discon-
nectthenegativecablefromyour
car, then from the booster battery.
Disconnect the positive cable f rom
your car, then the booster battery. Start your car. If the starter motor
still operates slowly, check the
jumper cable connections to make
sure they have good metal-to-
metal contact.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until all are
disconnected. Otherwise, you may
cause an electrical short.
The numbers in the illustration show
you the order to connect the jumper
cables.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
