PRECAUTIONS
^ The oxygen sensor has a permanently attached wire and connector. This should not be removed, since removal will affect proper operation of the oxygen sensor.
^ The oxygen sensor may be difficult to remove when engine temperature is below 120°F. Use caution, since excessive force may damage threads in exhaust manifold or pipe.
^ If old sensor is being reused, coat threads with anti-seize compound, then install into manifold or pipe.
