Now I have an anti-freeze leak at the thermostat housing. I replaced the gasket and used RTV silicone on both sides of the gasket and reinstalled everything. Fired it up and let it build pressure and still leaks....GRRRR. It is a chrome housing...is that the problem? I've heard they can cause trouble.
Pull it off draw file it ,true it up , no silicone use permatex aviation gasket sealer it’s black and goes on with a brush get a new paper gasket and try again .leaks suck!
