hello people,
My car has been recently overheating close to the red zone. So i checked to see if the thermostat is playing up by feeling both radiator hoses. The upper hose would be scorching hot compared to the lower hose, which was at a reasonable temperature. I went to Super-cheap Auto and bought a new gasket and thermostat. I get home, take off the thermostat housing, scrape off the old gasket, install the new gasket on the housing, then tension up one of the bolts. When i got to the 2nd and last thermostat housing bolts, it seemed to be going in fine, until it started getting tighter and tighter. I kept tightening the bolt until i realized that the thread of the bolt completely demolished the thread inside the hole. I pull it out and noticed aluminum scrapings all over the thread of the bolt. I thought, "****, this isn't good".
Now, I'm just wondering, is it possible to make a whole new thread into the thermostat housing hole and screw in a marginally larger bolt through? Or is it better to just go to the wreckers and purchase an inlet manifold from there? I've given the inlet manifold to my mate who will give it to his dad to check out. He knows anything and everything about metal, bolts, threads etc....
P.s. While we were taking out the inlet manifold, a bit of coolant went in the valley and down a hole. at the back end. Is this okay? I got some paper towels and soaked up all the coolant that fell in.
