Engine Oil
Adding Oil
To add oil, unscrew and remove the engine oil fill cap on top of the valve
cover. Pour in the oil, and replace the engine oil fill cap. Tighten it securely.
Wait a few minutes and recheck the oil level. Do not fill above the upper
mark; you could damage the engine. Recommended Oil
Oil is a major contributor to your
engine's performance and longevity.
Always use a premium-grade deter- gent oil.
You can determine an oil's SAE
viscosity and Service Classification from the API Service label on the oilcontainer.
A fuel-efficient oil is recommended for your Honda. This is shown on the
API Service label by the words "Energy Conserving". This oil is
formulated to help your engine use less fuel. The API Service label also tells you
the service classification of the oil.
Always use an oil that is labeled "API Service SJ". This service rating may
include other classifications, such asCD. These additional classifications
are not a problem, as long as the
label also carries the SJ classification.

Engine Oil

The oil container may also display the API Certification seal. Make sureit says "For Gasoline Engines." The SAE numbers tell you the oil's
viscosity or weight. Select the oil for
your vehicle according to this chart.

An oil with a viscosity of 5W-30 is
preferred for improved fuel economyand year-round protection in your

Honda. You may use a 10W-30 oil if

the temperature in your area never

goes below 20°F( — 7°C).
Synthetic Oil
You may use a synthetic motor oil if it meets the same requirements
given for conventional motor oil; energy conserving, a service
classification of SJ, and the proper
weight as shown on the chart. When using synthetic oil, you must follow
the oil and filter change intervals given in the maintenance schedule.
Additives Your Honda does not need any oil additives. Purchasing additives for
the engine or transmission will not
increase your vehicle's performance or longevity. It only increases the
cost of operating your vehicle.

Changing the Oil and Filter
Always change the oil and filter according to the time and distance (miles/kilometers) recommenda-
tions in the maintenance schedule.
The oil and filter collect contami- nants that can damage your engine if
they are not removed regularly.
Changing the oil and filter requires
special tools and access from
underneath the vehicle. The vehicle should be raised on a service station-
type hydraulic lift for this service. Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled mechanic.
1. Run the engine until it reaches normal operating temperature,
then shut it off. 2. Open the hood and remove the
engine oil fill cap. Remove the oildrain bolt and washer from the
bottom of the engine. Drain the oil into an appropriate container. 3. Remove the oil filter and let the
remaining oil drain. A special
wrench (available from your Honda dealer) is required to
remove the filter.

6. Refill the engine with the recom-

mended oil.

Engine oil change capacity (including filter):

5.1 US qt(4.8 l ,4.2 Imp qt)

7. Replace the engine oil fill cap. Start the engine. The oil pressure
indicator light should go out within
five seconds. If it does not, turn off
the engine and reinspect your
work.
8. Let the engine run for several minutes and check the drain bolt
and oil filter for leaks. 9. Turn off the engine, let it sit for
several minutes, then check the oil
level. If necessary, add oil to bring
the level to the upper mark on the
dipstick.

Improper disposal of engine oil can be
harmful to the environment. If yon
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.

Cooling System

Adding Engine Coolant
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 for leaks.
This coolant should always be a mixture of 50 percent antifreeze and50 percent water. Never add straight
antifreeze or plain water. Always use Genuine Honda
antifreeze/coolant. If it is not
available, you may use anothermajor-brand non-silicate coolant as a
temporary replacement. Make sure it
is a high-quality coolant recommended for aluminum engines.
However, continued use of any non-
Honda coolant can result in
corrosion, causing the cooling system to malfunction or fail. Have
the cooling system flushed and refilled with Honda antifreeze/
coolant as soon as possible. If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.

RESERVE TANK

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.ProCarManuals.comMain Menu Table of Contents s t

Cooling System
1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counter- clockwise, without pressing downon it, until it stops. This relieves
any pressure remaining in the
cooling system.
3. Remove the radiator cap by
pushing down and turning
counterclockwise.

4. The coolant level should be up to the base of the filler neck. Addcoolant if it is low.
5. Put the radiator cap back on. Tighten it fully.

6. Pour coolant into the reserve tank.Fill it to halfway between the MAX
and MIN marks. Put the cap back on the reserve tank.

Cooling System

Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or engine components.
Replacing Engine Coolant
The cooling system should be completely drained and refilled with
new coolant according to the time
and distance recommendations in
the maintenance schedule. Only useGenuine Honda antifreeze/coolant.
Draining the coolant requires access
to the underside of the vehicle. Unless you have the tools and
knowledge, you should have this maintenance done by a skilled
mechanic. 1. Slide the heater temperature
control lever to maximum heat.Open the hood. Make sure the
engine and radiator are cool to the
touch.
2. Remove the radiator cap. 3. Loosen the drain plug on the
bottom of the radiator. Thecoolant will come out through the
hole in the splash cover.
