Over the past few days I have noticed my 93 LS making a whining noise. Kind of like turbo spooling up or like engine noise though the radio. The noise gets louder the more I accelerate. I can hear it inside the car and outside when my friend drove it. Having really changed anything except PVC value, oil change and drain/fill trans fluid? Car runs fine just annoying sound. Like a jet on take off. Maybe something in the air to intake? I noticed that little electrical box on the air intake but don't know if that could be what it is since I don't know what that box does. Air filter was changed couple hundred miles ago so its clean.

Sounds like the clutch fan is going bad. Same thing happen to my car and when I got another one from the junkyard the sound stopped.

It could be the power steering pump leaking fluid or low on fluid(my first guess). Take it to the shop and get it check out.

Power steering pump was replaced 2 weeks ago, how can I check the fan clutch?

check your PS levels................

Just checked PS levels and they are right on the money. Any other ideas? How can you check the fan clutch?

got it done last month about 500.oo job in fremont , cali lexus
whine like a duck call.

how could you tell that is what it was? does the fan still work? did it only whine when the fan clicked on?
did the noise get louder with higher RPMs?

Hi my dads car does the same sound, but it is only there when th A/C is on. Could it be the fan clutch?

i had have the car make the sound in front of the mechanic for them to lacote the spot and then go in and llok for the loose part. my suggestion is to do that. I had it done becuase i use my car for business and couldn't have an embarrising noise like that coming from my car.

best of luck

I was able to get the noise to work really loud 2-3,000 rpm. in park. with heay throttle. So during normal driving the sound would only come when you pressed the gas just right. The clutch had become worn internally. it rotates on a rod i assume( not a mechanic here folks, but i pay for one) and wasa wobbling instead of a true rotation. the sound for me was like a flute or bird call. FREAKY

Do you have any aftermarket stereo work? Weren't you installing a Sub? Whines through the speakers almost always come from the alternator.

My stereo equip hasn't come in, so its not that. The alt is acting weird (dim lights when i hit brakes, vic versa) but I didn't now it could make a noise like that?

The whinning noise does increase when the rpms increase. Just take it by your lexus dealer and ask them to listen to the car they will usually do it free of charge.

when i had an sc300 it did the same thing, couldnt figure it out for nothing, turned out that it was my clutch fan. the fan stays on all the time and as the engine gets hotter there is a circuler coil witch expands in the middle of the fan that cause the fan to spin faster to cool the engine. that is known to go bad and cause an embarising squilling noise. just buy the clutch for the fan from the dealer and remove the fan and replace the clutch in the middle if fan. its not expensive and not hard at all. and let me know if I saved the day!!!!!!!!!!!!!!!!!!!!!!!
