sounds like could be alternator bearings, and is cheaper to replace unit than try to repair, to try to check with the engine running ,place the tip of a LONG screw driver carefully on the alternater as near to the belt as you safely can and place the handle to your ear , this works like a stethascope and you will here metal grinding sound if bearings are wearing , you will know if the sound is right by comparing with another vehicle keep me posted if you wish , PLEASE BE VERY CARE FULL , DO NOT LET THE SCREWDRIVER SLIP INTO THE DRIVE BELT
It sounds to me that your belt or tensioner is worn, if the noise goes away when the ac is off then it is just the belt slipping, it takes a lot of power to run the compressor and if the belt is worn it most likely slipping on the pully when you engage the clutch.
Have your drive belt replaced (sometimes called the auxiliary or serpentine belt) when it slips it creates a screeching noise and it's also a sign that it's going to fail (snap).
These can run the alternator and power steering so you should change it as a preventative measure.
Try slipping the drive belt (fan belt, alternator belt, or whatever you want to call it) off the engine, then run the engine momentarily without the belt. If the noise disappears, at least you now know it is not an internal engine problem, and it will be an issue with one of the pulleys, or belt-driven accessories.
Ouch, sounds as if the timing belt may have failed or slipped (now mechanically out of time). I tend to think this as you mentioned it was running and then shut down with clunking noise (not pistons hitting valves I hope)
Remove the distributor cap and crank the engine over, if the rotor does not move the belt broke. The belt drives the cams which inturn drives the distributor.
Pleas let me know your results so I may possibley assist further.
The fan might be "louder" because it may have been allot more quiet with the old failing fan clutch and not spinning fast enough.. Thus the new one working correctly making the fan spin much faster and being "louder"..
If that makes sense - to you question..
