Has Naty here have many things, first the cylinder head has been repaired many times without any results, and they have changed things that neither stick or join, the first thing that should be checked is that the electro fan between operation when it must, your listening that starts or do you see it? Second already ruled out that it is a button joint, that is, that there is the presence of water in the oil, this is presented as an emulsion strain coffee with milk in the oil filling lid or in the level rod of the same, that there is no oil in the water, in the deposit of expansion of water or in radiator itself, it is presented as a multicolored trail in the coolant, something like when you wash the plates after eating the plates after eating the plates after eating the plates after There is no presence, water is water in the combustion chamber, it is presented as a white cloud, it leaves from the exhaust tube that never disappears and due to the decrease in the level of water without losses that are seen on the ground, and finally that there is the presence of compression in the water system, this is checked taking out the radiator cover and starting if it jumps a stream of water as well as in a pool, it is bad.
If none of these factors appear, the correct functioning of the electro -ventilator, this fan has 2 speeds if it leaves in the second that the vehicle is higher tends to heat up, if it does not go in any check fuses and relays, if everything is fine, you check the bulb you take out the connector of this and a bridge is made between its bins if the fan starts Starting the fan, before saying that this is the fault, it must be bleed or remove That is, before reaching 96 degrees, which is Peugeot's working temperature, a parallel installation can be done to make the fan start and stop the fan intermittently to a lower temperature, to avoid overheating, Eye Peugeot has a land that goes from the negative battery terminal, by the cable ignored, which goes to the gearbox if it does not have good contact, or this is release A very easy 13 mm bolt to see, let me know how you are going to do the parallel installation to give you the information on how it is done.
