1992 HONDA PRELUDE maintenance schedule

Engine Oil

Oil and Filter Changes

Always change the oil and filter according to the time and mileage
recommendations on the mainte-
nance schedule. The oil and filter collect contaminants that can dam-
age your engine if they are not
removed regularly. Changing the oil and filter requires
special tools and access from
underneath the car. The car 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 oil
filler cap. Remove the oil drain
bolt 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.

Maintenance
CONTINUED

The oil, engine components
and the exhaust system are
hot and can burn you.
Use caution and wear protec-
tive clothing while working in
the engine compartment.
Repeated, prolonged exposure
to used motor oil may cause
skin cancer.
Wash your hands thoroughly
with strong soap as soon as possible after handling used oil. OIL FILTER

Cooling System

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. Add
coolant 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.

Do no t
add any rust inhibitors or
other additives to your car's
cooling system. They may not be
compatible with the coolant or
engine components.

Replacing Coolant

The cooling system should be
completely drained and refilled
with new coolant according to the
time and mileage recommendations in the maintenance schedule. Only
use recommended antifreeze.
Draining the coolant requires
access to the underside of the car.
Unless you have the tools and
knowledge, you should have this
maintenance done by a skilled
mechanic.

Engine Belts, Tires

Engine Belts

Check the condition of the two
engine belts. Examine the edges of
each belt for cracks or fraying.
Check the tension of each belt by pushing on it with your thumb
midway between the pulleys.
The belts should have the following "play" or deflection.
Alternator belt:
10.0 — 12.0 mm (0.39 — 0.47 in)

Power steering belt:
13.5 — 16.5
mm
(0.53
—
0.65 in)
If you see signs of wear or loose-

ness, have your dealer adjust or

replace the belts. Your dealer will
check these belts as part of the

normal scheduled maintenance.
Tires

Check the inflation and condition
of your car's tires at least once a

month.

Inflation

Check the pressure in the tires
when they are cold. This means the car has been parked for at least
three hours. If you have to drive
the car before checking the tire
pressure, the tires can still be
considered "cold" if you drive less than one mile.
If you check the pressure when the
tires are hot (the car has been
driven several miles), you will see
readings 28 to 41 kPa (0.3 to 0.4
kg/cm2, 4 to 6 psi) higher than the
cold reading. This is normal. Do not
let air out to match the specified
cold pressure. The tire will be

underinflated.

Storing Your Car
If you need to park your car for an
extended period (more than 1
month), there are several things
you should do to prepare it for
storage. Proper preparation helps
prevent deterioration and makes it
easier to get your car back on the
road. It is best to store your car indoors if at all possible. Fill the gas tank.
Change the engine oil and filter

(see page 137).

Wash and dry the exterior
completely.
Clean the interior. Make sure the
carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Reverse (5-
speed) or Park (automatic). Block the rear wheels.
If the car is to be stored for a
longer period, it should be
supported on jackstands so the
tires are off the ground.
Leave one window open slightly
(if the car is being stored indoors).
Disconnect the battery.
Cover the car with a "breathable" car cover, one made
from a porous material such as
cotton. Nonporous materials,
such as plastic sheeting, trap
moisture which can damage the
paint. If possible, run the engine for a
while periodically (preferably once a month). If you store your car for 12 months
or longer, have your Honda dealer
perform the inspections called for
in the 24 months/48,000 km (30,000
miles) maintenance schedule as
soon as you take it out of storage
(see page 133). The replacements
called for in the maintenance
schedule are not needed unless the
car has actually reached that time or mileage.

Emission Controls

The burning of gasoline in your
car's engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx) and hydrocarbons (HC).
Gasoline evaporating from the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to form photochemical "smog."
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas.
The Clean Air Act

The United States Clean Air Act*
sets standards for automobile
emissions. It also requires that
automobile manufacturers explain
to owners how their emission
controls work and what to do to
maintain them. This section
summarizes how the emission con-
trols work. Scheduled maintenance

is on page 129 .

* In Canada, Honda vehicles

comply with the Canadian Motor
Vehicle Safety Standards (CMVSS)
for Emissions valid at the time they

are manufactured.
Crankcase Emission Control

System

Your car has a Positive Crankcase
Ventilation (PCV) System. This
keeps gasses that build up in the engine's Crankcase from going into
the atmosphere. The PCV valve
routes them from the crankcase
back to the intake manifold. They
are then drawn into the engine and

burned.

Evaporative Emission
Control SystemAs gasoline evaporates in the fuel
tank, a canister filled with charcoal
adsorbs the vapor. It is stored in
this canister while the engine is off.
After the engine is started and
warmed up, the vapor is drawn into the engine and burned during

driving.
