During the operation of Peugeot 206, during the winter period, the reagents that are sending roads get into the poorly protected parts of the engine's hinged equipment. For example, the salt is affected by the rollers of the drive belt, the coupling of the air conditioner, and the electric connectors of the fan relay. The most dangerous is the oxidation of an engine control unit connector that can cause it to break out. You should periodically check the state of the connectors so that you do not have to change the expensive details.
