I have an issue with my serpentine belt that only happens when the roads are wet. The serpentine belt will come off the pulleys. I have checked the alignment (by eye) and it all seems kosher. I even put a new tension-er and belt on (hours of fun). There is no issue when the roads are dry, but as soon as it is wet, it will religiously throw the belt off. I was told that it is a frequent problem with these cars. Something about the splash guard on the lower right front hitting the belt run. But I cannot see the problem there since every time the belt comes off, the only way to get the thing on again is to remove the wheel and splash guard to gain access to it. There is only one way for the guard to affix to the frame. I am thinking about replacing the "Idler" pulley but I hate to throw money at a problem and not know if that is the issue.

3.8L? Is belt routed as in diagram?

Yep, that is how I repeatedly have been routing it. It is solid when dry, but when the roads are wet, the belt is guaranteed to fall off. I cannot tell you which pulley the belt is slipping off from. When I put the belt on and run the engine, I do not see any "Wobble" from any of the pulleys. There is no squealing or sign of binding when it is running (while it is dry). All the pulley mounts are tightly affixed to their brackets.

Maybe worn pulley on water pump assume it is real shinny and slick. You said water shield in place so that is out. Try this engine running spray water at crank see what happens.

That is a good idea. I will give that a shot. The water pump pulley does not look too shiny but the idler pulley is very shiny. Thanks for your help.

Check alignment of pulleys and belt does belt fray on edges? If so it is a sign of being out of alignment. Use a straight edge or laser light if possible.

The power steering pump may be your problem as well.

I am assuming this is 3.3 as you have a 3.2L and they do not make that. I am sending a belt diagram along see if yours is like this. You might also have a mechanic put a belt tension gauge on it to see what it is.
