To fit
- Fit the sensor provisionally so that the cable runs along the water pipe. Change the O-ring if necessary and lubricate it with engine oil.
- Spray the connector with Kontakt 61 (part no. 30 04 520), press together the connector and fit it in the holder.
- Secure the cables with the retaining clip. Take care not to pinch or damage the cables with the clip.
- Press in the sensor and screw it on with the O-ring fitted together with the heat shield. Make sure the O-ring is positioned correctly so that the sensor bottoms in the engine block. Otherwise, there is a risk of the sensor mounting lug breaking off.
- Lubricate the screw for the exhaust manifold heat shield with Molykote 1000 or equivalent (part no. 30 20 271) and fit the heat shield.
- Start the engine and check for oil leaks.
