Does anyone else here have this problem? On my 05 anytime I drive through a puddle that presumably gets water on the serpentine belt, it will make the LOUDEST, most ungodly squeal/chirping when I stop (which I also assume correlates with whatever RPM's are at when idling in gear, is it 600 RPM?).

The belt itself is less than a year old, no signs of cracks or any deterioration. The tensioner seems to be ok since the little tick marking on the side is positioned right about where it should be in relation to the other three marks. Is it possible that the tensioner is getting loose in spite of that? The belt will also chirp on WOT gear changes every time. The tensioner is the original factory tensioner, and I'm at right about 103,000 miles on the odometer.

The main reason this bothers me isn't really the noise since the belt drys off pretty quickly. It's the possibility that I have belt slippage that bothers me as I've got a DC Power HO alternator, and I can't afford it not being driven quickly enough to support two batteries and many other electronics.
