I own a 1998 chevy tahoe. It has just hit 131,000 miles. 5.7 litre v8. On cold mornings, after my suv has sat all night cold, when I first start it up in the mornig it will make a whirring noise. That is the best way I can describe it. It only lasts a few seconds. Does anyone know what this could be and what should I do to fix it. Please help. Thanks :mrgreen: to me it sounds like some sort of pump or assist making this noise. As far as I can tell when sitting in the drivers seat, the sound seems to be located near the pressure assist for the brakes or somwhere around the computer system. It seems the longer it sit cold the longer the sound will last. Or maybe the colder it gets the longer the sound. Sometimes its maybe a split second, sometimes it seems to be 2 or 3 seconds, if not longer : :shock:
have the same problem?
