Valves, Springs, and Valve Seals Installation
Special Tools Required
Valve spring compressor attachment 07VAE-00101 0A
1. Coat the valve stems with engine oil. lnstall the
valves in the valve guides.
2. Check that the valves move up and down smoothly.
Installthe spring seats on the cylinder head.
Install the new valve seals (A) using the valve guide
seal installer (B).
NOTE: The exhaust valve seal (C) has a black spring(D), and the intake valve seal (E) has a white spring(F). They are not interchangeable.
6.
lnstallthe valve spring. Place the end ofthe valve
spring with closely wound coils toward the cylinder
n eao.
Install the valve retainer.
Installthe valve spring compressor, Compress the
spring, and install the valve keepers. Remove the
valve spring compressor.
Lightly tap the end of each valve stem two or three
times with a plastic mallet (A) to ensure proper
seating of the valve and valve keepers. Tap the
valve stem only along its axis so you do not bend
the stem.

ECM Data
You can retrieve data from the ECI\4 by connecting the OBD ll scan tool or the Honda PGM Tester to the data link
connector (DLC). The items listed in the table below conform to SAE recommended practice. The Honda PGM Tester
also reads data beyond that recommended by SAE to help you find the causes of intermittent problems.
The "operating values" listed are approximate and may vary depending on the environment and the individual
vehicle.

Trouble Code(DTC}
lf the ECM delects a problem, it will store it as a code

from the crankshaft position (CKP) sensor. This data is

1. After checking and recording the freeze data, reset
the ECM (see page 1 1-4). lf there is no freeze data of
the misfire, just clear the DTC.
2. Start the engine, and listen for a clicking sound
from the injector at the problem cylinder.
Does the injector click?
YES-Go to step 3.
NO-Go to step 30.
3. Turn the ignition switch OFF.
4. Exchange the ignition coil from the problem
cylinder with one from another cylinder,

Front and Rear Suspension
WheelAlignment
The suspension can be adjusted for front camber, front
toe, and rear toe. However, each of these adjustments
are interrelated to each other. For example, when you
adjust the toe, the camber changes. Therefore, you
must adjust the front wheel alignment whenever you
adjust the camber or toe.
Pre-Alignment Checks
For proper inspection and adjustment of the wheel
alignment, do these checks:
1. Release the parking brake to avoid an incorrect
measurement.
Make sure the suspension is not modified.
Check the tire size and tire pressure
Tire size:
Front/rear: 195/60R15
Tire pressure:
Front: 230 kPa {2.3 kgf/cm',33 psil
Rear: 210 kPa |'2.1 kgf/cm', 30 psi)
Check the runout of the wheels and tires.
Check the suspension ball joints. (Hold a wheel
with your hands, and move it up and down and
right and left to check for wobbling),
2.
3.
Bounce the vehicle up and down several times to
stabilize the suspension.

Front Caster lnspection
Use commerciallv available comDuterized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
eouioment manufacturer's instructions.
Check the caster angle. lf the caster angle is not within
the specification, check for bent or damaged
susoensron comoonents.
Front caster angle: 1'40't 1"
