• Tightening Specifications: 55 Nm
• Coat new oxygen sensors with an assembly paste.
• When installing the previous oxygen sensor, coat the thread with hot bolt paste. Refer to the Electronic Parts Catalog (ETKA).
• Assembly paste or hot bolt paste must not enter the slots on the oxygen sensor body.
• Always install the oxygen sensor wire in the same location so it does not come into contact with the exhaust pipe.
• When installing, bring all cable ties back to the same positions.
