Oxygen Sensor Socket
Warning: Exhaust manifold becomes very hot during engine operation.
Caution:
The oxygen sensor has a permanently attached wire and connector. This should not be removed or pulled on, as any change in circuit
resistance will affect engine performance and emissions.
Caution:
Excessive force may damage threads in exhaust manifold or pipe.
1.
Disconnect oxygen sensor electrical connector.
2.
Using a suitable tool (tool # C-4907 or equivalent), carefully remove the sensor from exhaust manifold or pipe. The oxygen sensor may be easier
to remove when engine temperature is above 120°F.
3.
Clean threads in exhaust manifold with an 18 mm X 1.5 + 6E tap.
4.
If a new sensor is being used, verify that the threads are coated with anti-seize compound, before installing in manifold or pipe.
4.
If a used sensor is being installed, coat sensor threads with a nickel based anti-seize compound (Loctite 771-64 or equivalent), then install sensor
in manifold or pipe. Do not use graphite or other anti-seize compounds.
5.
Torque the oxygen sensor to 20 ft-lbs (27 Nm), connect wiring.
