The task of replacing the water pump has progressed, but I have hit a snag.
The coolant return line from the heater core changes from rubber to metal on the passenger's side of the engine. The metal pipe goes across the front of the head and then joins the water pump with a flange and an o-ring seal. In the middle of the pipe is a bracket that is bolted to the head. That bolt has a 5 mm allen recess. I have used a socket-drive allen bit to try to remove the bolt, but the bit just turned in the recess, rounding it out. Of course, the bolt isn't the most accessable, as the attached picture shows. Any suggestions on how to get it out?
