I have a 2003 Kia Optima with a 2.4L engine. I picked up a high frequency engine vibration that can be felt in the hood and right fender at idle and in the steering wheel at all driving speeds. I replaced both belts (no defects noted) and checked all the accessory pulleys & bearings for roughness or play. Everything normal except water pump makes a noise - if you're a deer hunter, it sounds like a doe bleating! No problems with engine temp though. What next?
