It is the alternator....
Alternator is defective and needs replacing.
1. Suspect the belt is loose. Tighten it or use belt dressing. 2. Bearings are worn out on the alternator. Replace the alternator. 3. Poor workmanship on a rebuilt alternator. Replace the alternator.
It is probably the alternator that is whining - and not charging so you have run out of battery power and it won't turn over.
How do you replace an alternator on 2008 dodge Avenger? My car is making a whining noise and this may be the problem.
the bearings are probally giving out.
I would say probably not, the reason your battery is weak is I reckon due to a fault with your alternator. It is obviously not producing sufficient power (electricity ) to keep the battery charged. The whining noise is probably caused by worn-out bearings. A replacement or re-conditioned alternator should cure the problem .
Whining noises often come from the alternator or the steering pump. Check the power steering fluid in the pump (there is a dipstick on the pump), and have an AVR test done on the alternator. If the alternator is faulty, you are probably having battery problems as well. If the steering pump is low on fluid or is faulty, you probably are experiencing jerky steering from time to time.
sounds like the alternator belt is loose, check it out and let me know.
It might make a whining or grinding noise, or it might not make any noticeable noise at all. All depends on what exactly with the alternator is malfunctioning. You're better off to have your alternator bench tested (which can be done free at any major auto parts retailer) than relying on sound to tell you if it's malfunctioning.
The whining could be related to the alternator. Does the car have any electrical problems such as the battery drains and dies while car running, are your belt(s) tight? in good condition? It might be a belt tensioner or idler pulley that is causing the whining.
could be the fuel pump...or the alternator...:)
Worn bearing and new belt is tighter than worn one?
Faulty wheel bearings usually squeak or squeal. A whining noise is more likely to come from a power steering pump low on fluid, or from a faulty alternator.
One source of whining could be many things but the first that comes to my mind is the Alternator. The CV joints could possibly make this noise too but I would personally consult a mechanic about this. any motor attached to the engine could be a cause but I would take it to a mechanic: alternator, compressor, water pump, etc.
Check your power steering fluid level. If low...add. Listen for the area from which the whining comes from. Could be the A/C compressor as well
Check the power steering pump for the cause of the noise. I sounds like the pump is causing the whining and is either low on fluid or possibly going bad.
It could be your power steering pump, check power steering level. Also could be alternator or AC bearings.
Can be the alternator going bad, water pump going bad, or a transmission problem. Have this diagnosed by a professional.
The correct way to spell it would be "whining".
There are generally two signs that the alternator is going bad. First is the noise. A new noise will begin to be heard. Something like a whining when the car is accelerating. Second is the smell. You may smell burning from the engine department.
my sister is whining because she couldn't have her toy
It could be a bearing in your alternator that has gone out. Start your car and do whatever it takes to reproduce the sound. When the vehicle is making the sound, put a screw driver against your alternator and put your ear against the other side of the screw driver. If you hear the whining noice clearly through the screw driver, it's probly the alternator. Move the screw driver around the area and see if the noise that is passed through the screw driver is louder anywhere else, besides the alternator. If not, it's coming from your alternator. You can use a long screw driver or any solid piece of material, but the handle of a screw driver is a little more comfortable against your ear than other options.
The cause of the whining noise in the front end of a 2004 supercharged Monte Carlo, especially during cold weather, is the idler pulley. This is located at the driver's side of the engine between the alternator and a/c pump.
