hi all newby here. i have an 02 1.9tdi galaxy which has just started to overheat on certain journeys. When its under pressure. Garage diagnosed the thermostat but i am going to change it myself. I cant find any pictures of where it is without having to buy a manual. Does anyone have any pictures showing what i am looking for?i have looked at all the forums and they are a bit confusing. I am going to start with the thermostat and see from there? thanks
