I have a coolant leak comming from this area. It is the pipe that runs underneath the exhaust manifold along the side of the block. There is a flange on the end of it that is leaking. I'm pretty sure the gasket is broken since simply tightening it did not resolve the issue. I unbolted the flange and cannot move the pipe to replace the gasket. Is there a bolt holding the pipe in place under the exhaust manifold?
