Attention: When applying a protective coating to the bottom, the lambda probe must be open.
Withdrawal
Remove the engine cover over the injectors.
Raise and support the vehicle.
Unplug the lambda probes and separate them.
Loosen the wire holder.
Unscrew the lambda probes from the exhaust manifold. At the same time, turn the wires by hand so that they do not pinch.
Attention: Lambda probes are not cleaned or lubricated with any lubricants.
Apply high temperature grease only to the lambda probe threads.
Attention: If the lambda probe is screwed in without high-temperature grease, then over time the thread «grab» and the lambda probe will be almost impossible to turn out. The new lambda probe already has this special grease on the threads.
Screw the lambda probes into the exhaust manifold and tighten to 30 Nm.
Attach the electrical wire and connect the plug. The wire must be laid so that it does not fray and does not touch the hot parts of the exhaust system.
Install the engine covers.
