[TR] cleaning cooling system

> Anyone have a suggested method or sequence for flushing the system?

Especially if you don't want to mess with that plug, my suggestion would be
to take it to your local radiator shop and pay them to flush it.  Most of
them have a gizmo that injects water mixed with air and chemicals, which
shakes loose gunk much better than what you can do with a hose; even with
the drain open.
