RE: Engine whine while accelerating
Welcome to the site.
What size engine do you have? A whine could be a bad bearing, either water pump, idler pully, alternator, or the serpentine belt tensioner. If you can identify it as coming from the passenger side of the engine which is where the serpentine belt is at, you might be able to track it down to one of these items. One trick is to take a long handled screwdriver and put the blade on the shaft or component that you think is making the noise and put your ear against the handle. This is basically a cheap stethoscope. You should be able to hear the whine or noise more vividly. Just make sure you don't get caught in the pullies or belt. If you can give some more feedback, we might be able to help you track it down.
