used to be a gear head - now I ask for help.
2001 Caravan - great vehicle - I love it! I bought it for my wife about a year ago. It has developed a symptom that concerns us. It is a low volume whine from the engine compartment. It is high frequency and it tracks engine RPM - not transmission speeds. Definitely not Power Steering. Oil levels [tranny, engine, power steering fluid] are spot on and no burnt odor. It runs great - getting good mileage. We are taking it in to get it diagnosed - but not being familiar with all the pumps and gadgets under the hood anymore, I was hoping some of you had a thought.
