pull off the top coolant line..and blow the air all the way out...this happened to us also it was just simple as getting all the air out of the coolant lines..


make sure that the surface of the head and the pipe are clean take a wire brush if u have one they work good if not use a putty knife.and if that dont work look for cracks in the pipe.
