Engine Oil
Maint enance255
Improper disposal of engine oil can be
harmf ul to the environment. If you
change your own oil, please dispose of
the used oil properly. Put it in a sealed
container and take it to a recycling
center. Do not discard it in a trash bin
or dump it on the ground.

Clean off any dirt and oil that have
collected around the ignition coils. Remove the two bolts and the f our
nuts with a wrench and remove
the tower bar. Then remove the
A/C tube f rom the three clips.
Remove the two bolts and the
three nuts with a 7/16 inch (10
mm) wrench, then remove the
engine cover.
The spark plugs in your car are a
special platinum-tipped design f or
longer lif e. The spark plugs should
be replaced according to the time
and distance recommendations in
the maintenance schedule.

Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
af ter it contacts the cylinder head.)
Tightening torque: Put the A/C tube back in place.
Install the tower bar and tighten
the two bolts and the f our nuts.
Tightening torque:
Push the wire connector onto the
ignition coil. Make sure it locks in
place. Install the engine cover. First
tighten the two bolts on the front
of the engine cover, then tighten

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.

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
.)
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. 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. 338

AIR CONDITIONING CONDENSER
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.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.

Block the rear wheels.
Fill the f uel tank.
Change the engine oil and f ilter
(see page ).
Wash and dry the exterior

carpeting, floor mats, etc. are

Leave the parking brake off. Put
the transmission in Park.
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 possible, run the engine f or a
while periodically (pref erably once
amonth).
Leave one window open slightly (if
the vehicle is being stored
indoors).
If you store your car f or 1 year or
longer, have your Acura dealer
perf orm the inspections called f or in
the 2 years/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 vehicle has
actually reached that time or mileage.
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. Disconnect the battery.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield. 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. Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Nonporous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.

T aking Care of t he Unexpect ed307

Start the engine and watch the oil
pressure indicator. If the light
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. (Seeon page .)
Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or a moment, then
recovered. If the indicator stays on
with the engine running, it shows
that the engine has lost oil pressure
and serious engine damage is
possible. In either case, you should
take immediate action. If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ). Let the vehicle sit f or a minute.
Open the hood and check the oil
level (see page ). Although oil
levelandoilpressurearenot
directly connected, an engine that
is very low on oil can lose pressure
during cornering and other driving
maneuvers.
