Strange noise after Flood

[nevinst]

Help!

We recently received a pretty good rain that resulted in som high flood waters along my route to work. During my drive I got into water that flowed at least to the top of my tires. Even taking it slow, I had water push up over my hood once or twice.

Afterwards I experienced a couple temporary problems from various things getting wet that are easily explained. (Clutch shudder, brake squeals, etc...)

Now after 5 or 6 days, I am hearing a high frequency vibration associated with engine RPM that shows up mainly when the engine is warm and the RPM is winding down.

It's hard to explain, but here goes.....When I am slowing to turn or stop, I usually down shift and I am getting this LOUD vibration as the RPM reaches the bottom end (1200 - 1000). As I push the clutch in and let off the pedal to downshift, the RPM drops all the way to idle and the noise really intensifies 'till the RPM bottoms out. Then for a brief period, as I excellerate, the noise shows up again for a short (1/2 second or so) period. Occasionally, I can rev the engine and hear the same noise but not always.

My first suspect is the cooling fan. Would this be likely? If so, can I correct this or will it corret itself? What about a bearing along the serpintine belt path. (Tensioner, Alternator, etc...) Any guesses? Any other things I need to watch for?

Sorry this post is so long, but I know you guys can help.

Thanks,

Troy
