New serpentine belt smokes, squeals, and there are metal shavings

While on the highway my temperature light, voltage light, and check engine light came on. I also noticed what felt like a loss of power steering and heat. I figured it was my alternator and I just nursed it home. After 15 minutes I noticed my lights (interior and exterior) dimming and figured my battery was dying. Finally (close to home, thankfully) it died. I had a friend look at it. The serpentine belt had snapped. We took the alternator to an auto parts store to have them test it just to be sure. It tested out just fine. After my friend put the new serpentine belt on, the car started with a jump to the battery. Almost instantly it made an awfully squealing noise (maybe metal on metal) followed by some smoke. We shut the engine off. My friend looked around and noticed metal shavings underneath and around the belt. We are stuck now. Unless I am more ignorant when it comes to mechanics than I think I already am, I believe the serpentine belt is the only belt. At least it's all I see. After skimming this site and a few others I have seen everything suggested from water pump, to pulleys, to ac compressor, to bearings and so on. I guess first of all - is this a problem or natural, the smoke and squeal. I shut the car off immediately as my initial reaction. I didn't give it time to stop in fear it might cause other, bigger issues. Secondly, if it is an issue, what might it be??

SOURCE: trying to figure out why i am having squealing issue all new altternator power steering pump pulleys and belts

Belts normally squeal when they slip and they slip because they're not tight enough or in the case of a V belt because they're too narrow. Make sure they're tight enough and they're the right belt.

WHAT IS THE LIKELY CAUSED OF A LOUD SQUEALING NOISE COMING FROM THE ALTERNATOR SERPENTINE DRIVE BELT SYSTEM ? IS IT THE ALTERNATOR OR SERPENTINE BELT?


serpentine belt is getting old and hard and the cold weather was causing it to slip
check belt condition ( small cracks across the grooves = scrap and get a new one) and check tension

Do serpentine belts stretch?


serpentine belts do not stretch as you describe because the tensioner keeps them tight so they just break. It is probably hard and cracking and need s a new one so try that first . The ac has nothing to do with the belt as it will be a low gas problem from leaks and the heat is a coolant problem or a control problem from inside the car.. The grinding sound may be a pulley bearing or some other bearing failing. Why don't you take it to a repair shop to find all the faults so that you can work out how much it is going to cost.

Squealing


My first impression would be the serpentine belt is worn ...specifically it has "glazed" and stretched so it no longer has the ability to effectively grip the drive pulleys it spins. Typically when the serpentine belt loses "traction" it will squeal as it slips on the metal pulleys of the accessories it is designed to operate. There also may be a problem with the the tensioner ...a device used to keep proper tension on the serpentine belt. This is an easy and relatively inexpensive repair ...probably cost between $100 and $200 ...depending on whether the tensioner needs replacing.
You really need to get this fixed. If the serpentine belt fails ...it breaks or comes apart ...you will lose power steering and the water pump as the two critical accessories the belt operates. Obviously the loss of power steering can make the car difficult to drive and the loss of the water pump will cause an engine overheat condition fairly quickly. The A/C and alternator will also drop off line but these aren't as critical as the steering and water pump.

Squeals are usually belts or bearings, check your serpentine belt for cracks and damage . There are it'd products like stop squeal you can use on your belt. If its the belt it will work, otherwise check bearings on all pulleys.

Hole in cam - metal shavings


if your cambelt slipped or broke you have got bent valves which you will need to take the head off to do,if its the pd engine it is common for the cams to wear but you normally lose power and the engine is very noisey,changing the cams and the hydraulic tappets will cure this problem

Engine Squeals


i would have to say that the timing belt is worn and stretched out for normal wear and tear. The check engine light is probably for the same reason. If the timing belt is not quite right it will throw a timing code for the camshaft being out of sync due to the excess slack that is in the timing belt.
