To add oil, unscrew and remove the
engine oil f ill cap on top of the lef t
valve cover. Pour in the oil, and
replace the engine oil f ill cap.
Tighten it securely. Wait a f ew
minutes and recheck the oil level. Do
not f ill above the upper mark; you
could damage the engine.Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines.’’
Pour the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could damage components in the engine
compartment.
Oil is major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements. It is
highly recommended that you use
Honda Motor Oil in your car f or as
long as you own it.

API CERTIFICATION SEAL

µYou may use a synthetic motor oil if
it meets the same requirements
given f or conventional motor oil: it
displays the API Certif ication Seal,
and it is the proper weight as shown
on the chart. When using synthetic
oil, you must f ollow the oil and f ilter
change intervals given in the
maintenance schedule.
The numbers on the container’s label
tell you the oil’s viscosity or weight.
Select the oil f or your car according
to this chart.
An oil with a viscosity of 5W-30 is
pref erred f or optimum f uel economy
and year-round protection in your
Acura. You may use a 10W-30 oil if
the temperature in your area never
goes below 20°F ( 7°C). Your Acura does not need any oil
additives. Purchasing additives f or
the engine or transmission will not
increase your car’s perf ormance or
longevity. It only increases the cost
of operating your car.

Always change the oil and f ilter
accordingtothetimeanddistance
(miles/kilometers) recommenda-

The oil and f ilter collect contami-
nants that can damage your engine if
they are not removed regularly.Run the engine until it reaches
normal operating temperature,
then shut it off.
Open the hood and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.Remove the oil f ilter and let the
remaining oil drain. A special
wrench (available f rom your Acura
dealer) is required to remove the
f ilter.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.

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.

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

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.
