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.

Tires

Replacing Tires

The tires that came with your Honda were selected to match the
performance capabilities of the car
and provide the best combination of
handling, ride comfort, and long life.
You should replace them with
radial tires of the same size, load
range, and speed rating. Mixing
radial and bias-ply or bias-belted tires on your car can reduce its
braking ability, traction, and
steering accuracy.
It is best to replace all four tires at
the same time. If that is not possi-
ble or necessary, then replace the two front tires or the two rear tires
as a pair. Replacing just one tire
can seriously affect your car's han-

dling.

If you ever need to replace a wheel,
make sure you use the same wheel
that originally came on your Honda.
Replacement wheels are available
at your Honda dealer. Wheels and Tires

DOT Tire Quality Grading

(US Cars)

The tires on your car meet all U.S.
Federal Safety Requirements. All
tires are also graded for treadwear,

traction, and temperature perform-
ance according to Department of

Transportation (DOT) standards.

The following explains these

gradings.
Treadwear

The treadwear grade is a compara-

tive rating based on the wear rate
of the tire when tested under con-

trolled conditions on a specified

government test course. For exam-

ple, a tire graded 150 would wear

one and one half (1-1/2) times as

well on the government course as a
tire graded 100. The relative per-

formance of tires depends upon the

actual conditions of their use, how-

ever, and may depart significantly

from the norm due to variations in

driving habits, service practices

and differences in road character-

istics and climate.

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.

Emission Controls

Exhaust Emission Controls

The exhaust emission controls
include four systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Catalytic
Converter. These four systems
work together to control the engine's combustion and minimize
the amount of HC, CO, and NOx
that comes out the tailpipe. The
exhaust emission control systems
are separate from the crankcase
and evaporative emission control

systems.

PGM-FI System
The PGM-FI System on your car
has three sub systems: Air Intake,
Electronic Control, and Fuel
Control. The Electronic Control
Unit (ECU) uses various sensors to
determine how much air is going
into the engine. It then controls
how much fuel to inject under all
operating conditions. Ignition Timing Control System
This system constantly adjusts the
ignition timing, reducing the
amount of HC, CO and NOx

produced.

Exhaust Gas Recirculation (EGR)
The EGR system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding ex-
haust gas to the air/fuel mixture re-
duces the amount of NOx produced
when the fuel is burned.
Catalytic Converter
The catalytic converter is in the exhaust system. Through chemical
reactions, it converts HC, CO, and
NOx in the engine's exhaust to
carbon dioxide (CO 2), dinitrogen
(N 2), and water vapor.
Replacement Parts

The emission control systems are

designed and certified to work to-

gether in reducing emissions to
levels that comply with the Clean

Air Act. To make sure the emis-
sions remain low, you should use

only new genuine Honda replace-

ment parts or their equivalent for

repairs. Using lower quality parts
may increase the emissions from

your car .

The emissions control systems are

covered b y
warranties separate

from the rest of your car. Read

your warranty manual for more
information.
