Removal Procedure
Notice: Handle the oxygen sensors carefully in order to prevent damage to the component. Keep the electrical connector and the exhaust inlet end free of contaminants. Do not use cleaning solvents on the sensor. Do not drop or mishandle the sensor.
Important:
• Remove oxygen sensors with the engine temperature above 48°C (120°F). Otherwise the oxygen sensors may be difficult to remove. • A special anti-seize compound is used on the oxygen sensor threads. New service sensors should already have the compound applied to the threads. Coat the threads of a reused sensor with anti-seize compound P/N 5613695 or equivalent.
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
- Disconnect the forward oxygen sensor electrical connector.
- Remove the forward (1) oxygen sensor from the exhaust manifold.
Installation Procedure
- Install the oxygen sensor (1) in the exhaust manifold.
- Connect the oxygen sensor connector.
- Lower the vehicle.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the heated oxygen sensor (HO2S) sensor to 41 N·m (30 lb ft).
