Flushing rad system
Don't waste your time, D2 radiators don't flush well if at all.
Take it to a radiator shop that can do an alluminum radiator, along with replacing the tanks. If it is over 100,000 miles and an estimate over $250, go buy yourself a new one from British Parts of Utah along with a new t/stat and coolant pressure cap.
When installing, do not use Dexcool, switch to Peak or one of the other coolants a make your engine happier.

Because a drain in the Radiator is inefficient and the dealer technicians don't use them anyway. There are also drains on each side of the engine block but I don't think anyone uses those either, they are difficult to access.
