My 2000 Mercury Villager has started making a whining sound when its running. It happens even in park but seems to get louder when I accelerate. It has 207,000 miles. Timing belt was replaced at around 150,000 miles.

What engine ? vacuum leak intake runner control , possibly ! Is the check engine light on ? Ford Windstar P0171 P0174 Upper Intake Manifold Gasket Replacement

Hi Tyler:
Try using a mechanics stethescope (or a dowel sound rod, thumb over end held against your ear) and with the engine running, touch various components. You will hear different sounds, and hopefully be able to isolate the whine.
CAUTION - Work Safe - moving bits can make the sound rod hurt you.
I'd be guessing at an alternator bearing as they whine worse than a puppy on the wrong side of a door.
Cheers

Sounds like a bearing is on its way out in the drive belt system, could be the alternator, idlers, a/c if fitted, water pump.

Disconnect drive belt and spin all pulleys, and you will feel if one is loose, tight or making a noise it shouldn't.

Belt may be slipping. Try some belt dressing.

Check your drivers side front CV joints and make sure the dust covers aren't ripped or broken. You;ll also want to check to make sure part of your splash guard isn't rubbing against your tire.

distributor probably.


gerry

Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).

This can be a power steering belt loose or the power steering pump malfunction. To check if it's a belt problem with engine running open the hood and pour a small ampunt of water (1/4 gal or a bit less) over the belt located on the left side of the engine if the sound lowers then it's most likely the belt only.

probably a broken exhaust manifold stud or 2. It usually is louder when cold.
