OXYGEN SENSOR
Removal and Installation Procedure
1. Disconnect the negative battery cable.
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. Do not drop the oxygen sen-
sor.
2. Disconnect the electrical connector.
3. Carefully remove the oxygen sensor from the exhaust
pipe.
Installation Notice
Tightening Torque
55 NSm (41 Ib-ft)
Important:A special anti-seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphitewill burn
away, but the glass beadswill remain, making the sen-
sor easier to remove. New or serviced sensors will al-
ready have the compound applied to the threads. If a
sensor is removed from any engine and is to be rein-
stalled, the threads must have an anti-seize compound
applied before reinstallation.
4. Coat the threads of the oxygen sensor with an anti-
seize compound, if needed.
5. Installation should follow the removal procedure in
the reverse order.

GENERAL INFORMATION
CLEANLINESS AND CARE
An automobile engine is a combination of many ma-
chined, honed, polished and lapped surfaces with toler-
ances that are measured in the ten-- thousanths of an
inch. When any internal engine parts are serviced, care
and cleanliness are important. A liberal coating of en-
igne oil should be applied to friction areas during assem-
bly, to protect and lubricate the surfaces on initial
operation. Proper cleaning and protection of machined
surfaces and friction areas is part fo the repair proce-
dure. This is considered standard shop practice even if
not specifically stated.
Whenever valve train components are removed for ser-
vice, they should be kept in order. They should be
installed in the same locations, and with the same mat-
ing surfaces, as when they were removed.
Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnectcables may result in damage to wire harness or other
electrical parts.
ON-- ENGINE SERVICE
Caution: Disconnect the negative battery cable be -
fore removing or installing any electrical unit, or
when a tool or equipment could easily come in con-
tact with exposed electrical terminals. Disconnect -
ing this cable will help prevent personal injury and
damage to the vehicle. The ignition must also be in
LOCK unless otherwise noted.
Notice:Any time the air cleaner is removed, the intake
opening should be covered. Thiswill protect against ac-
cidental entrance of foreign material, which could follow
the intake passage into the cylinder and cause exten-
sive damage when the engine is started.
