Thermostat housing leaking
I have a 1995 Wrangler 4 cyl. 2.5 liter automatic. I was replacing my thermostat and bought a new housing because the old one was corroded. When I put the new thermostat and housing on the engine and poured coolant in the radiator the thermostat housing leaks from the bottom bolt. I cleaned the old gasket and sealant material off of the engine and applied new permetex sealant on both sides of the new gasket. When I tightened the housing and filled the radiator with coolant, I still got the same leak. I also tried using ATV sealant, but got the same results. I tried tightening the bolt to stop the leaking, but I over torqued it and the bolt head snapped. I extracted the bolt and inspected the new housing I had bought. It looked like there may have been a crack in the housing near the leak area, so I returned it to Autozone. I took my replacement thermostat housing, coated the gasket, bolts, and bolt holes with permetex copper sealant, and still get the same leak from the bottom bolt area . Any ideas what I should do next?
