Whinning noise from engin.
2005 Grand Caravan 3.3. This weekend we had high water. Had to drive through about 16 inches of it. It then turned cold and two days later when I went to start the van it would not start. Had to boost and then still no joy for the first few minutes (think the starter was frozen). Once started, it started making a whining sound that you can controll with the gas. The more the gas pedal is down, the higher the whine. It is not the belts; when the hood is up it sounds like it's coming from the top or back of the engine. Any ideas or input to start me in the right direction? Thanks
