cleaning solvents of any type. Oxygen sensor may be difficult to
remove when engine temperature is less than 120
removal force may damage threads in exhaust manifold or pipe.
2) Raise and support vehicle. Remove splash shield.
Disconnect retaining tab from connector. Disconnect oxygen sensor
electrical connector. Carefully remove oxygen sensor from exhaust
pipe.
Removal (4.0L & 4.6L - Bank 1 Sensor 1)
1) Ensure oxygen sensor is free of contaminants. DO NOT use
cleaning solvents of any type. Oxygen sensor may be difficult to
remove when engine temperature is less than 120
removal force may damage threads in exhaust manifold or pipe.
2) Raise and support vehicle. Disconnect negative battery
cable. Support rear of powertrain. Remove rear frame bolts. Lower
frame 3". Disconnect rear oxygen sensor electrical connector. Remove
rear oxygen sensor.
Removal (4.0L & 4.6L - Bank 1 Sensor 2)
1) Ensure oxygen sensor is free of contaminants. DO NOT use
cleaning solvents of any type. Oxygen sensor may be difficult to
remove when engine temperature is less than 120
removal force may damage threads in exhaust manifold or pipe.
2) Disconnect negative battery cable. Disconnect harness
connector from oxygen sensor. Carefully remove oxygen sensor from
exhaust pipe.
Removal (4.0L & 4.6L - Bank 2 Sensor 1)
1) Ensure oxygen sensor is free of contaminants. DO NOT use
cleaning solvents of any type. Oxygen sensor may be difficult to
remove when engine temperature is less than 120
removal force may damage threads in exhaust manifold or pipe.
2) Raise and support vehicle. Disconnect negative battery
cable. Remove front splash shield. Disconnect front oxygen sensor.
Remove oxygen sensor.
Removal (5.7L)
NOTE:
Procedure applies to all oxygen sensors (4).
1) Ensure oxygen sensor is free of contaminants. DO NOT use
cleaning solvents of any type. Oxygen sensor may be difficult to
remove when engine temperature is less than 120
removal force may damage threads in exhaust manifold or pipe.
2) Raise and support vehicle. Disconnect oxygen sensor
electrical connector. Carefully remove oxygen sensor. For Camaro and
Firebird sensor locations, see Figs. 3-6. For Corvette sensor
locations, see Figs. 7-9.
CAUTION: Correct torque of oxygen sensor is critical to prevent
crushing glass beads in graphite anti-seize compound.
Crushing glass beads will cause sensor to seize in exhaust
manifold. This may necessitate replacement of exhaust
manifold upon next removal.
Installation
1) Whenever an oxygen sensor is removed, coat threads with
anti-seize compound before installation. New oxygen sensors already
have this compound applied to threads.
2) Install oxygen sensor. Tighten oxygen sensor to
specification. See TORQUE SPECIFICATIONS. Reconnect harness connector
to oxygen sensor. Reconnect negative battery cable.
