NOTE The oxygen sensor has a permanently attached pig-tail and connector. This pig-tail should not be removed, since removal will affect proper operation of the oxygen sensor.
REMOVAL
- Disconnect electrical connector from oxygen sensor.
- Using suitable wrench, carefully remove sensor from exhaust manifold or pipe.
Caution
The oxygen sensor may be difficult to remove when engine temperature is below 120°F. Excessive force may damage threads in exhaust manifold or pipe.
INSTALLATION
- If new sensor is being used, install sensor into manifold or pipe.
- If old sensor is being reused, coat threads with anti-seize compound, Part No. 5613695 or equivalent, then install into manifold or pipe.
