4. Install a new oil filter according to
instructions that come with it.
5. Put a new washer on the drain bolt,
then reinstall the drain bolt.
Tighten it to:

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.

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 fluidlevel by removing the cap and
looking at the float. It should be up
to the top of the neck. If the float is at the bottom of the neck, the
reservoir is nearly empty.
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 the
windshield washer reservoir.
Antifreeze can damage your vehicle's
paint, while a vinegar/water solution
can damage the windshield washer

pump.

Use only commercially-available
windshield washer fluid.

Transmission Fluid

Automatic Transmission
Check the fluid level with the engine
at normal operating temperature.
1. Park the vehicle on level ground. Shut off the engine.
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 securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should bebetween the upper and lowermarks. 5. If the level is below the lower
mark, add fluid into the filler hole
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 shift quality. Have the transmission
drained and refilled with Honda
ATF as soon as it is convenient.
6. Insert the dipstick all the way back into the transmission securely as
shown in the illustration.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen-
dations in the maintenance schedule.

Transmission Fluid

5-speed Manual Transmission Check the fluid level with the
transmission at normal operating temperature and the vehicle sittingon level ground. Remove the
transmission filler bolt and carefully
feel inside the bolt hole with your
finger. The fluid level should be up
to the edge of the bolt hole. If it is
not, add Genuine Honda Manual
Transmission Fluid (MTF) until it starts to run out of the hole. Reinstall
the filler bolt and tighten it securely. If Honda MTF is not available, you
may use an API service SG, SH or SJ
grade motor oil with a viscosity of SAE 10W-30 or 10W-40 as a
temporary replacement. An SG
grade is preferred, but an SH or SJ
grade may be used if SG is not available. However, motor oil does
not contain the proper additives and
continued use can cause stiffershifting. Replace as soon as
convenient.
The transmission should be drained and refilled with new fluid according
to the time and distance recommen- dations in the maintenance schedule.

Brake and Clutch Fluid
Check the fluid level in the reser-
voirs monthly. There are up to two reservoirs, depending on model.
They are: Brake fluid reservoir (all models)
Clutch fluid reservoir
(manual transmission only)
The brake fluid in the brake system should be replaced according to the
time and distance recommendations
in the maintenance schedule. Always use Genuine Honda DOT 3
brake fluid. If it is not available, youshould use only DOT 3 or DOT 4
fluid, from a sealed container, as a
temporary replacement. However,
the use of any non-Honda brake fluid can cause corrosion and decrease
the life of the system. Have the brake system flushed and refilled
with Honda DOT 3 brake fluid as soon as possible.
Brake fluid marked DOT 5 is not
compatible with your vehicle's
braking system and can cause extensive damage. Brake System
MAX
The fluid level should be between the MIN and MAX marks on the sideof the reservoir. If the level is at or
below the MIN mark, your brake system needs attention. Have the
brake system inspected for leaks or worn brake pads.
