Hello Ya' ll

I had a head gasket leak and decided to do the repair myself. Everything was going well until I was tightening a coolant pipe hose on the LIM thermostat housing (I don't know what the pipe hose thing and LIM thermostat housing is really called but I am trying my best to explain it. Correct me please!). I tighten it to hard and then heard a snap or pop. Then I looked at it real good and seen a crack on top I have a picture.

I want to know if JB weld could fix this little crack? If so, What would be the best way to do it?

Thanks

Well, I guess I will give it a try and see what happens.
