Installing

Installation of oxygen sensor is in reverse order of removal. Note the following.

• Wires of oxygen sensors must always be secured in the same position when installing so that contact with the exhaust pipe is avoided.

• New oxygen sensors are coated with assembly paste; the paste must not get into slots of oxygen sensor body.

• For a used oxygen sensor, only coat threads with hot bolt paste. This paste must not come into contact with sensor slots.
