Yesterday I drove through some sandy water, and the water went into my engine compartment. Today, I have a weird noise coming from under the hood. Let me describe it to you. First I thought it was the power steering, because it had that whine like power steering. I filled up that, and still got the sound. It sounds like a belt pully has some sand between it and the shaft possibly in the bearings somewhere. It's a humming, grinding noise. Didn't have any noise before yesterday.
