Loud whirring noise at start-up

My car makes a terrible, loud whirring noise when the engine is started from cold. After driving it enough for the engine to warm up it usually goes away. Does anyone know the cause?

The first thing to check would be to make sure the power steering reservoir is not running near empty, locate the filler cap for the power steering pump it should be marked and then add the appropriate amount making sure you don't over fill, that may make the sound go away if not we must move on to the next possibility, by the way if the noise gets louder when you turn the steering wheel it is most likely the power steering pump or fluid level is low.

Power steering reservour may have plugged screen. Fluid flows better when warmer weather thus, no noise of starving power steering. Have a look at this link. http://www.youtube.com/watch?v=_QjBLYltLYY

Whirring vibrating sound

As long as it virtually goes when warmed up, don't worry. When starting from cold remember P & N aren't actually driving the transmission. Point to note, Jaguar say no servicing of auto-trans necessary - this is NOT true - fluid AND filter should be changed about every 25/30 thousand kms.

2000 Beetle Loud Whirring at start up

its your secondary air pump. it turns on in the cold morning to inject more air into your exhaust, something about emission. its normal to be high pitched. once on my car it was way loud, i looked and the hose had disconnected. either way its normal if its not super loud. but if its everyone is looking at me loud then check for loose hoses!

Engine noise at cold start-up.

Sounds like your oil pump inside the engine is not pumping oil fast enough when you start your vehicle its common problem for mitsubishi motors my car does the same thing.
