REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts to specified torques.

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in the figure (2 at strut and 1 at body panel). When installed, harness must not be twisted.

Checking Exhaust SystemEBS00AZ6
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

If anything is found, repair or replace damaged parts.
Removal and InstallationEBS003DN
CAUTION:

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance and shape.

Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.

Be careful not to cut your hand on the insulator edge.

EXHAUST SYSTEM


Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.

Install seal bearings at exhaust front tube and main muffler as follows.
CAUTION:
Do not mix the bolt and spring for seal bearing as the dimension is different for each seal bearing.
Exhaust Front Tube Side (QR20DE and QR25DE)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with
exhaust front tube flange.
Main Muffler Side (QR20DE, QR25DE and YD22DDTi)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with main
muffler flange.
INSPECTION AFTER INSTALLATION

With the engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

PRECAUTIONS

Precautions for Servicing CompressorEJS000T5

Plug all openings to prevent moisture and foreign matter from entering.

When the compressor is removed, store it in the same position as it is when mounted on the car.

When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer to AT C - 2 4 , "
Maintenance of Lubricant Quantity in Compressor" .

Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubri-
cant, wipe it off by using a clean waste cloth moistened with thinner.

After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.

After replacing the compressor magnet clutch, apply voltage to the new one and check for usual
operation.
Precautions for Service EquipmentEJS000T6
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer’s instructions for tester operation and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched off
after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.

Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.

For pumps without an isolator, use a hose equipped with a man-
ual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.

If the hose has an automatic shut-off valve, disconnect the hose
from the pump. As long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump's
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
