It started out with replacing the exhaust manifold and that fixed first leak now I have water pouring out behind engine have replaced heads with gaskets bypass hose and water pump and still leaking how the hell can ford get away with making an engine that I'm sure they new would fail you don't have to be a rocket scientist to know that plastic is going to melt on a hot engine is there any way of getting any money back that I spent. I still haven't found the source of the leak but still looking.
