Crazy idea?

[81Wagon]

So there I was at an intersection, half an hour ago, watching the smoke drift its way out the driver's window of the SUV in front of me. Well, at least she didn't have the windows rolled up with young children trapped in the car (as was the case when my best friend's aunt would pick us up from camp years ago - "Why do you kids keep rolling down the windows? It's COLD out there! Stop it!").

The light turned green and, apparently nearing the end of its useful life as a cancer inducer, the cigarette was tossed backwards out the window at me as the woman started her way cross the intersection.

THis is the second day in a row that someone has thrown a burning piece of trash out of their car directly in front of me (I am all for the $3,000 to $20,000 fines proposed here in California for said crime).

Anyway, my first though was "if only one of my windshield wiper nozzles was aimed the other way, I could douse her!" (or at least her car ;-). Following that, I imagined it might be interesting to mount an extra tank and nozzle at the grille aiming outward... I could imagine the occasional situation where it would be useful, and at least it would be better for the environment than some other methods of retribution .

For the record, I'm not advocating a potentially illegal and dangerous idea, this was merely a thought experiment .

But it did lead to another, more legitimate idea: turn that hypothetical extra nozzle at the grille around and point it at the radiator! Could this technique be used to spray water on the radiator (hopefully resulting in additional cooling as the water evaporates/boils off) in extreme conditions?

For example, there are many long stretches of steep hills on the highway in the desert between Las Vegas and the Utah border. I've made the trip in cooler weather and my wagon made it up each one, but it got VERY close to 120 degrees a few times. I imagine in the middle of the hot summer (when I am planning yet another trip, loaded up with passengers and possibly a trailer) the situation might be worse. It would be interesting to see if wetting the radiator would help alleviate the problem!

Can anyone think of any down-sides to such an experiment? Could spraying cool water on a hot radiator cause a problem? Will it make any difference? Am I crazy?
