OXYGEN SENSOR (O2S1)
Removal Procedure
1. Remove the air cleaner/resonator assembly. Refer to
Section 1B, SOHC Engine Mechanical.
2. Remove the oxygen sensor.
Disconnect the oxygen sensor connector (1).
Remove the oxygen sensor (2).
Notice: The oxygen sensor uses a permanently at-
tached pigtail and connector. This pigtail should not be
removed from the oxygen sensor. Damage or removal
of the pigtail or the connector could affect proper opera-
tion of the oxygen sensor. Take care when handling the
oxygen sensor. Do not drop the oxygen sensor.
D12F547A
Installation Procedure
1. Install in the reverse order of removal.
Important: A special anti–seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphite will burn
away, but the glass beads will remain, making the sen-
sor easier to remove. New or service sensors will al-
ready have the compound applied to the threads. If a
sensor is removed from any engine and if for any reason
it is to be reinstalled, the threads must have anti–seize
compound applied before reinstallation.
2. Install the oxygen sensor.
Tighten
Tighten the oxygen sensor to 35~44 Nm (26~33 lb-
ft).

2A–6 SUSPENSION DIAGNOSIS
DAEWOO M-150 BL2
WHEEL BEARING DIAGNOSIS
This vehicle with non–serviceable bearings in the rear
wheels. If any fault is found with a wheel bearing, it must
be replaced.
Wheel Bearing Noise
A road test usually reveals excessive wheel bearing
noise. Wheel bearings emit a howling sound when loose
or damaged. Wheel bearing noise is present only when
the vehicle is moving. It is constant and unwavering and
increases with the speed of the vehicle. If the wheel
bearing noise cannot be positively diagnosed, or if theorigin of the noise cannot be determined, perform the
following test :
1. Raise and suitably support the vehicle.
2. Spin the wheels using your hand. Check for out–of–
round or out–of–balance tires, bent rims, or loose
wheel bearings.
3. Spin the rear wheels using a commercial wheel spin-
er.
4. If a noise can be heard from the passenger compart-
ment, replace the noisy wheel bearings. Refer to Sec-
tion 2D, Rear Suspension.
5. Lower the vehicle.
