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.
I had that problem with mine finely replaced it and is good so far but not a crime one.
