mystery 'whirrrring' noise at stoplights...
can someone please tell me if it is 'normal' to hear a strange 'whirring' noise every time i stop at a stop light? if i'm sitting at a complete stop, after a second or two, the noise starts, like the sound of a small power drill starting under the hood? the sound only lasts for about 5 seconds.
normal? cooling mechanism? pump? fan? secondary water pump? paranoid?
