I was driving along and bam I smelled antifreeze like crazy and truck shot up to hot. I stopped and some metal line that goes into the intake has rusted off completely and water was shooting out of the intake in the hole the pipe came off of. Can anyone tell me what the technical name for the hard line that comes out the intake towards the back passenger side of a 5.4L v8 in a 1999 150? I hope the pic comes up so you can see the line im speaking of. How hard is it to repair that line? The metal piece is the one laying over near the positive battery cable with the clamp on it
