Engine Oil
The oil container may also display the API Certification seal. Make sure
it says "For Gasoline Engines."
API CERTIFICATION MARK 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.

Engine Oil

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 oil
drain bolt and washer from the
bottom of the engine. Drain the oil into an appropriate container.

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 another
major-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.

Maintenance

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.

RESERVE TANKProCarManuals.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 down
on 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 MAXand MIN marks. Put the cap back
on the reserve tank.
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.

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 drain through the
splash guard. Remove the drain
bolt and washer from the engine
block.

10. Turn off the engine. Check the level in the radiator, add coolant ifneeded. Install the radiator cap,
and tighten it fully.
11. Fill the reserve tank to the MAX mark. Install the reserve tank cap. Windshield Washers

Check the level in the windshield
washer reservoir at least monthly during normal usage. In bad weather,
when you use the washers often, check the level every time you stop

for fuel.

The windshield washer reservoir is located behind the driver's side
headlight. Check the reservoir's fluid
level by removing the cap and
looking at the level gauge attached
to the cap.
Fill the reservoir with a good-quality
windshield washer fluid. This increases the cleaning capability and
prevents freezing in cold weather.
Do not use engine antifreeze or a vinegar/water solution in thewindshield washer reservoir.
LEVEL GAUGE

Antifreeze can damage your vehicle's

paint, while a vinegar/water solution
can damage the windshield washer

pump.

Use only commercially-available

windshieId washer fluid.

2. Remove the dipstick (yellow loop) from the transmission and wipe it
with a clean cloth. 3. Insert the dipstick all the way into
the transmission.
4. Remove the dipstick and check the fluid level. It should bebetween the upper and lower
marks.
5. If the level is below the lower
mark, add fluid into the tube to
bring it to the upper mark. Always use Honda Premium Formula
Automatic Transmission Fluid (ATF). If it is not available, you
may use a DEXRON ®
III
automatic transmission fluid as a
temporary replacement. However, continued use can affect shiftquality. Have the transmission
drained and refilled with Honda
ATF as soon as it is convenient.
6. Insert the dipstick all the way back in the transmission.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen- dations in the maintenance schedule.

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

Turning the steering wheel to full left
or right lock and holding it there can
damage the power steering pump.
