Answer the only true way to stop a leaking head gasket is to replace it Answer I couldn't agree more. Coolant sealer doesn't know the difference between internal passages and exterior leaks Answer It works for some people. If your car's not worth the actual repair, which can be hundreds or thousands of dollars, it's worth a try.
Coolant sealer tells the difference between internal passages and leaks by the much higher temperature of the engine Answer From my experience, while it may stop the headgasket leak for a while, it may also restrict the radiator, heater core, and internal engine passages.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
