To add oil, unscrew and remove the
engine oil f ill cap on top of the valve
cover. Pour in the oil, and install 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.’’
Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
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.
Honda Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection.

The oil’s viscosity or weight is
provided on the container’s label.
Select the oil f or your vehicle
according to this chart.
5W-20 oil is f ormulated f or year-
round protection of your Acura, to
improve cold weather starting, and
to help your engine use less f uel.
If 5W-20 oil is not available, a 5W-30
oil may be used. However, it should
be replaced with 5W-20 at the next
oil change.You may use a synthetic motor oil if
it meets the same requirements
given f or a 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.
Your Acura does not require any oil
additives. Additives may adversely
af f ect your engine’s or transmission’s
perf ormance and durability.

Always change the oil and f ilter
accordingtothetimeanddistance
(miles/kilometers) recommenda-
tions in the maintenance schedule.
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 car. The car 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.

, 3.9 Imp qt)
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.

If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks.
The coolant you add should always
be a mixture of 50 percent antif reeze
and 50 percent water. Never add
straight antif reeze or plain water.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.
Always use Honda All Season
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 percent
antif reeze and 50 percent water. It
does not require any additional
mixing. If it is not available, you may
use another major-brand non-silicate
coolant as a temporary replacement.
Make sure it is a high-quality coolant
recommended f or aluminum engines.
However, 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.

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.

Put the radiator cap back on.
Tighten it f ully. The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Remove the radiator cap by
pushing down and turning
counterclockwise. Turn the radiator cap counter-
clockwise, without pressing down
on it, until it stops. This relieves
any pressure remaining in the
cooling system. 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 car’s cooling
system. They may not be compatible
with the coolant or engine compo-
nents.
