DW170-010 Oxygen Sensor Removal and Installation Tool

Removal procedure

1. Disconnect the negative battery cable.

Note: The oxygen sensor has a non-detachable flexible lead and connector. Do not remove the flexible lead from the oxygen sensor. Damage to or removal of the flexible lead or connector will affect the operation of the oxygen sensor. Handle the oxygen sensor with care. Do not drop the oxygen sensor.

2. Disconnect the front heated oxygen sensor connector.

Caution! Cool the engine before removing the oxygen sensor. Removing the oxygen sensor on a hot engine may damage the threads in the exhaust manifold.

3. Using the oxygen sensor removal and installation tool DW170-010, carefully remove the front control oxygen sensor with electric heater.

Installation procedure

Important: A special anti-seize compound is used on the oxygen sensor threads. This compound consists of liquid graphite and glass beads. The graphite burns out, but the glass beads remain and make it easier to remove the sensor. New or repaired sensors already have the compound applied to the threads. If the sensor is removed from the engine or reinstalled, then it is imperative to apply the anti-seize compound to the threads before reinstalling.

1. If necessary, coat the threads of the control oxygen sensor with electric heater with anti-seize lubricant.

2. Using the oxygen sensor removal and installation tool DW170-010, install the front control oxygen sensor with electric heater into the exhaust manifold

Tighten

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