Most likely a tensioner pulley bearing(the smooth faced pulley)
I would remove the belt and see if the noise is gone.
A wooden dowel or long screwdriver held to your ear is a
good way to find the noise,just put it on the metal and be
careful !!

SOURCE: engine overheating ============ Went fine at

Don't know what the "whirring" is, but you NEED to find it. The only reason your temp. goes down at higher speed, is cuz more air is rushing past your car, cooling the engine and radiator. Careful you don't burn up the engine! Find the cause of the overheating, probably related to the sound you hear, or caused by overheating, even maybe causing the overheating. Take your time and work on it or have it serviced. Start by checking your coolant level. Good luck.

SOURCE: How can you tell when the water pump on a 2004 Dodge Ram 1500 Truck with a 5.7 Hemi engine is going bad?

You could pull the serpentine belt and run the engine to see if the noise continues. The bearing for one of the pulleys could be failing, including the water pump and alternator.
It could also be the fan and fan clutch on the water pump.

I am hearing a noise, like a whirring sound that speeds up with the acceleration and makes no noise when in park. Does this sound like cv joint trouble?


a whirring sound can be a bearing on a component under the hood.(power steering pump,alternator,idler pulley bearing,etc),it can also be a serpentine belt from a worn belt or belt tensioner a cv joint won`t make a whirring sound(it will cause a clunking noise or a vibration).

2004 Maxima. God awful noise and banging and electric whirring sound when I press the brake pedal. We replaced the rotors and brakes, but noise is still there. What could it be?


remove rear wheel speed sensors and look for marks where rear hub has rubbed against sensor causing an erroneous wheel speed signal due to corosion.nissan has tech bulletin for this incident.

There is a whirring noise and the gears don't seem to be kicking in. The car is an slk automatic


It seems that your clutch plates have worn out. The automatic gears system uses a centrifugal clutch which automatically engages as the engine rpm increases. If the the plates are worn out, it will make a whirring sound as you rev the engine & there will be a loss of power transmitted to the wheels resulting in slow pick up of speed. Get the clutch plate assembly replaced.........sodeep

My 2000 Explorer makes a whirring sound when you accelerate - can this noise be due to a bent tierod? The previous owner had an accident involving the front end and was told that the tierod was haywire?


Typcially tie rods will only make a clunking noise or a squeak. The whirring sound if would suspect to be a wheel bearing. When you drive, slowly turn from left to right, if the pitch changes than its the bearing.

I have a whirring or griding in my drivetrain. I can coast donw a hill and let the engine idle and I still get the noise. It doesn't sound any different going around corners and gets louder as the speed...


this sounds like(no pun intended) you have a wheel hub bearing assembly failing. they will start a whirring or humming noise and then a growling or grinding noise the worse they get. from your description it is a rotational noise and gets louder and maybe a higher pitch as the vehicle speed increases. have this checked out right away so no further damage is done. they are not cheap assemblies as most GM and Saturn vehicles have the ABS sensor built into them(if your Vue has ABS).

2004 Chrysler Pacifica - Constant engine winding / whirring sound


If it sounds more like it's coming from rear of engine, that could be a possibility, and should be followed up,but if it's coming from front of vehicle area, I'd concentrate on your accessory drive belt . If it hasn't been changed in quite a while especially. That belt is routed around about 8 different pulleys,in,out,over,under, and it would lead me to believe it would be a good candidate for wear & noise that would increase as it wears more. I wouldn't try belt dressing as I'm not a lover of that stuff, only for emergencies. It may be as simple as spraying water on it to see if the noise changes or disappears, just keep your eyes back if engines running. They make what they call an audioscope, basically a set of headphones wired to an amplified probe, so it's easier to isolate the noise, perhaps a local garage has one, and can pinpoint it for you. Years back mechanics would use a long screwdriver or pipe up to their ear and poke around, but that's very dangerous, so I wouldn't recommend that. Your engine does have a timing belt too, and engines in the past have been known to produce that sound you describe from wear on it too. I'd go after that one as a last resort unless manual recommends it at certain interval.
