Installing

Installation is in reverse order of removal, note 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 sensor slots.

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

• During installation, all cable ties must be re-installed at the same location.

• Tightening Specifications. Refer to => [ Oxygen Sensors Assembly Overview ] Oxygen Sensors Assembly Overview.
