Installation
Installation in reverse order.
Note: New lambda probes are lubricated with mounting paste. Do not allow paste to get into the grooves of the lambda probe housing. When installing not new (used) lambda probes with high-temperature paste, only the threads must be lubricated. Do not allow paste to get into the grooves of the lambda probe housing. High temperature thread paste. When installing a lambda probe, its wire must be attached exactly in the same places. Electrical wiring must never come into contact with the exhaust manifold/downpipe.
