Can be the Alternator bearing or a serpentine belt pulley close by. A whistling noise can be a Vacuum leak. Sometimes when installing an Air filter, the ductwork is not reconnected perfectly.

A PCV valve can sometimes make a noise. The spring tension inside the PCV valve should keep it closed until a strong Vacuum pull opens it. This would usually be masked by the other engine noises at higher RPM.

About the only other thing you can do is use a water mist from a spray bottle on the engine seams as it runs. Follow vacuum lines and so on. Water will affect RPM so any openings can be detected.

My car keep on breaks alternator belts and it also makes this loud whistling noise. I've put on a new water pump, 3 alternators and several alternator belts


make sure that the pulleys of all the driven equipment are in alignment and not at a bit of an angle to the axis of the drive belt
To break belts something is not lined up properly or something is not turning freely

Whistling sound from engine after changing front battery


The whistling is possibly the alternator belt loading to charge the battery, listen to the noise and turn on the rear heated screen and headlight, if the pitch of the whistle changes then it's the alternator belt. Hope that helps.

Whistle noise


A whistling noise can be generated by an alternator at high RPM's and indicates a slip ring brush problem or a diode failing . It resembles a frequency whistle.. IT may also be from a leaking gasket and a partially blocked exhaust system from a failed cat converter and at speed and power, the exhaust gas is forced out the hole

What would cause whistling noise near pully and belt area noise gets louder with acceleration


The engine serpentine belt may be worn or wet. The belt slips, causing a high pitched squealing or whistle noise. The other possiblility is a bearing beginning to go out on one of your belt driven components

Why is my laser making a whistling noise right at 3500 rpms


Check the tension of your on the belts, check you or anyone has not bent one of the fan blades (cooling issue) Take the belt off the alternator see if you have any movement by trying to move the belt wheel if so then it's new alternator or new bushes. Hope this helps, Malcolm Campbell.

Engine whistling when cold in morning


Your alternator is drawing alot of power trying to charge the battery.Try tightening the belt.That should fix your problem..The reason the alternator is whistling so much on cold starts is because thats when it takes the most power from the battery to start the car.And the noise from the alternator is it charging it back up..So I'd try tighting the belt that will fix the smell and watch for the battery light or alternator light in the dash come on the could be your alternator failing and you dont want that to happen..I hope this helps you fix the problem.Have a great day...
