• Tightening Specifications: 55 Nm

• Coat new oxygen sensors with an assembly paste. This paste must not come into contact with sensor slots.

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

• The oxygen sensor wire must always be attached at the same location when installing. Do not the electrical wire connection come in contact with the exhaust pipe.
