2006 Buick Ranier Oxygen Sensor

It's screwed into the exhaust manifold really easy to change.

Hi rroniger,Welcome to 2carpros and TY for the donation.

On exhaust manifold, on right side of engine.See diagram below:

HEATED OXYGEN SENSOR REPLACEMENT - POSITION 1

TOOLS REQUIRED
J 39194-B Heated Oxygen Sensor Wrench

REMOVAL PROCEDURE

NOTE:
*Refer to Heated Oxygen Sensor (HO2S) Resistance Learn Reset Notice in Service Precautions.
*Refer to Heated Oxygen and Oxygen Sensor Notice in Service Precautions.

1.Disconnect the heated oxygen sensor (HO2S) electrical connector (1).
2.Remove the HO2S (2) using a J 39194-B.

NOTE: Refer to Excessive Force and Oxygen Sensor Notice in Service Precautions.

INSTALLATION PROCEDURE

IMPORTANT: Use special anti-seize compound on the heated oxygen sensor threads. The compound consists of graphite suspended in fluid and glass beads. The graphite burns away, but the glass beads remain, making the sensor easier to remove. New service sensors already have the compound applied to the threads. If you remove an oxygen sensor and if for any reason you must install the same oxygen sensor, apply the anti-seize compound to the threads before reinstallation.

1.Coat the threads of the heated oxygen sensor with the anti-seize compound P/N 5613695, or the equivalent if necessary.
2.Install the heated oxygen sensor (2) using a J 39194-B.

NOTE: Refer to Component Fastener Tightening Notice in Service Precautions.

Tighten the HO2S to 41 N.m (30 lb ft) .

3.Connect the HO2S electrical connector (1).

This is what Mitchell 1 is giving me Heated Oxygen Sensor (HO2S) No. 1 (4.2L) On exhaust manifold, on right side of engine.

Is your engine transverse? I'm using Mitchell 1 and Alldata auto references the professional version, don't know what Autozone is using.

Doesn't matter which side it say's it's on it's going to be in the exhaust manifold. Your engine only has one exhaust manifold so the sensor that is screwed into that manifold is going to be sensor one or aka the front o2 sensor.
