  Note
t  Threads of new Lambda probes are already coated with assembly paste; the paste must not get into the slots on the probe body.
t  In the case of a used Lambda probe grease only the thread with high-temperature paste. The paste must not get into the slots on the Lambda probe body. Locking fluid for hot working bolts → Parts catalogue
t  When installing, it is important to re-attach the Lambda probe wiring at the same locations to prevent it from coming into contact with the exhaust pipe.
