This has several things which could cause this noise. The idler pulley can cause a whining noise also the tensioner.The other item that causes that most often is the actual bearings in the alternator or power steering pump.check pump first for low fluid level.

What is a whistling noise behind the dashboard?


Many controls are activated by a vacuum line from the engine. My wild guess there is a slit or bad connection somewhere on the way to the control system. Good ears or "hearing horn" should help you find the sound source.

Got a 99 Nissan Altima 2.4, t-chain broke... replaced head and all t-components... start up surging idle and whistling off idle... engine runs smooth and great power off idle


the surging and whistling sounds like there might be a vacuum leak that is causing this.recheck all vacuum lines and surfaces were this is a gasket that seals a vacuum source.smooth running and good power off idle suggest this leak only affects the motor at a low(idle)rpm.

2000 LINCOLN TOWNCAR SIGNATURE SERIES LIMITED EDITION WHEN I START MY CAR IN THE MORNING I HEAR A LOUD WHISTLE- ING NOISE FOR 15 MINUTES UNTIL THE ENGINE WARMS UP AND WHISTLE NOISE STOPS. I REPLACED...


well it may help if you open the hood, then start the car and see if that helps you locate the item which is whistling. many cars have a power steering pump which likes to whistle until it gets warm. generally this is less than 5 minutes, and that is more like a screeching sound. something is either blowing out or sucking in through a small orifice to make the whistle, you need to physically locate the source of the sound. many bearings are in there spinning and any of them can be doing a cold screech.

myself I have been know to use a BFS, which is a big long screwdriver, i touch the pointy end to each of the spinning components and put the handle end to an ear. yes this process is not suggested for people with long hair or just no damn sense. but as i move the pointy end from component to component i know immediately when i touch it to the screechy one.

Whistling from engine


This is a symptom of the inlet manifold gasket having a leak.The whistling is air going in through the small leak/hole in the gasket.With the throttle butterfly shut,air is getting sucked in the only way it can.Try tightening the inlet manifold bolts 1st.But more than likely the gasket needs replacing.Hope this helps
