Installing

Installation is performed in reverse order of removal, noting the following:

• 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 oxygen sensor slots.

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