Dennis:

My leak is not the heater itself.  It was the gasket on the valve and
the line from the engine compartment.   My question was is there any
advantage to flushing the heater while I had things drained and apart or
should I just pre-emptively replace it?

> Flushing does not fix leaks. In fact will usually make leaks worse. Heater cores get flushed if clogged with debris and no longer heating. That indicates a complete set of other problems. With todays coolant even a marginally maintained system should not be loaded with enough debris to require cleaning or flushing.
