i took my thermostat housing to a guy so he could point it towards the front of the car so it would be easy to put on a radiator hose being a qualified engineer i thought he would do a good job but i went back and he said he tried to do it but the metal was too thin and burnt holes when i welded? so hes completely fucked it. can i use a 3TC one of these they look similar? has anyone else had this done?
