Note

t	The screw thread on the new lambda probe is coated with a special paste; the paste must not get into the slots on the probe body.

t	With used lambda probes, heat the bolt before coating with paste. The paste must not get into the slots on the probe body. For high-temperature paste refer to → Parts catalogue.

t	When installing, the Lambda probe wiring must always be re-attached at the same locations (under all circumstances) to prevent it from coming into contact with the exhaust pipe.
