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.
