Fiat Brava Thermostat 1.4 12v

Hello, I'm new to the forum, I think it's a very interesting forum, that goes ahead.
I have the thermostat of the fiat blocked and closed, I am used to having in my parents' house, a garage with all kinds of tools, pit, ... now that I live it was very much done. They ask me in a workshop for the thermostat and the sensor € 150, I do not know if it is expensive or not, I know that the pieces could cost me both for about € 40-50, and changing them never did but I suppose it is not complicated.
If someone can facilitate the workshop manual or make sure that it is not complicated and that you have to do to make sure, I will think where I can do it or take it to the workshop.
I hope I have understood me, thanks

Hello Solio, first of all welcome to the forum and the manualsdemecanica.com page, it is nothing of the other world to change thermostat Manual it seems to me that it is in the workshop manuals section, look for it to download manuals on this page are free so you will have no problems, good excito and any questions ask us, greetings.

When you change it and do the bleeding when starting it, it also opens the heating to circulate the water throughout the circuit and hopes that the radiator fan for more safety is booting at least twice.-
