A typical big CAT blows OUT through the radiator and away from the block. You actually may want a high capacity non-cloging fog nozzle aimed through the fan blasted at the radiator. There will be a lot of evaporation. THAT is very good from a cooling point of view, but you don't want the radiator growing a layer of insulating mineral deposits either. Evaporative cooling will do a LOT more cooling than just pissing the same amount as hot water down the drain The very fine mist helps keep mineral dist tiny and hopefully it will blow/wash away. Also a large fine mist is less apt to shock cool and crack any cast iron than a solid stream would. The corner hardware store generic hose nozzle set on a modest flow with reasonably fine mist is your best bet quickly, but can clog. Set too fine, and you won't get the volume you need. Longer term and maybe just for grins, look at the Bete cork screw nozzles (http://www.bete.com/products/app/misting.htm). You see them on snow making machines, in the upper corners of the sealed booth on X-files where cutting the black-ooze rock killed the FBI lab guy, and of course on the coating lines where M&Ms get colored. Alomst impossible to clog, too. If it isn't a major installation screwup (ducts to small, etc), fix whatever is wrong.

..if you want to risk cracking the block.. :/
I hope they clean the filters and change the oil while it is down, though.

YMMV, this is not professional advice. If this was professional advice, it would be accompanied by an invoice.
Speaking with a mechanical engineer, he suggested you may be able to restore some generator operation by continiously running a water/hose over the outside of the radiator. Not so much to clean it, but to act as once-through heat transfer to cool the engine.
I hope you can get it going again.
