I think he means getting rid of all leftover debris by flushing the engine (="block") completely, allowing higher pressures of water entering for a longer period of time then reversing the direction and keep switching between routes of "flushing" through the entire cooling system, including the engibe block itself.
The overheat problem probably runs somewhere else though. I suspect the wrong thermostat too. He has a lot of things to confirm before trusting it.
I heard citric acid works wonders but after ten years of car sitting untouched (AND unknown history of proper maintenance) I would definitely stop experimenting around the cooling system and probably would decide by a full (real full) tune-up... Valves adjusted --- at the minimum, then hoses, top gasket and all you can think of, including getting fresh nozzles, glowplugs, and maybe much more (check and flush and adjust pump, do waterpump, belts and possibly even check wiring).
I hope it turns out to be a great runner!!!
As #1, I dont get it why PO ran it without the thermostat.
