SA9603E Oxygen Sensor Remover/Installer

Caution: Refer to Battery Disconnect Caution in the Preface section.




1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
2. Disconnect the lower heated oxygen sensor connector.

Caution: In order to avoid being burned, do not service the exhaust system while it is still hot. Service the system when it is cool.

3. Using SA9603E , carefully remove the lower heated oxygen sensor from the front exhaust pipe.

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 sensor easier to remove. New or serviced sensors will already have the compound applied to the threads. If a sensor is removed from any engine and is to be reinstalled, the threads must have an anti-seize compound applied before reinstallation.

1. Coat the threads of the oxygen sensor with anti-seize compound, if needed.

Notice: Refer to Fastener Notice in the Preface section.

2. Using SA9603E , install the upper heated oxygen sensor to the front exhaust manifold.

Tighten
Tighten the heated oxygen sensor to 50 N·m (37 lb ft).

3. Connect the upper heated oxygen sensor connector.
4. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
