Noise whistling


check the idler pulley and tensioner I have seen this before coming from a idler pulley bearing on a Honda I sprayed some pb blaster/wd 40 on the center of the pulley and it stopped only for like 30 seconds but that's how I figured out which pulley was causing the noise


hope this helped

I just replaced power steering pressure hose on a 2002 Hyundai Sonata GLS 6 cylinder. Now its s squeals really bad when I turn the steering wheel and the belts are squealing like mad too what do I need to...


Looks like you need a new belt. Inspect the belt for any sign of damage like cracks etc. If belt appears fine then just tighten it. Add few drops of brake oil on pulley (surface which comes in contact with belt) to stop minor squeals if left after tightening the belt.

My brakes and power-steering are not working. The brake pedal is hard, but the brakes will not engage. The power steering was not working at the same time. It has brake fluid, but when I took the power...


Yes, your brakes are boosted by the power steering pump rather than by vacuum. I don't think it's air in the system. More likely your pump has failed, but you can try bleeding the pump. Here is a procedure from autozone.com:

Observe the following:
Use clean, new power steering fluid type only Hoses touching the frame, body or engine may cause system noise. Verify that the hoses do not touch any other part of the vehicle. Loose connections may not leak, but could allow air into the steering system. Verify that all hose connections are tight.


NOTE Power steering fluid level must be maintained throughout bleed procedure.

  1. Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.
    NOTE With hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF . This will discharge the hydro-boost accumulator.
  2. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure:
    1. Start the engine.
    2. Firmly apply the brake pedal 10-15 times.
    3. Turn the engine OFF

  3. Raise the vehicle until the front wheels are off the ground.
  4. With key in the ON position and the engine OFF , turn the steering wheel from stop to stop 12 times. Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.
  5. Verify power steering fluid level per operating specification.
  6. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
  7. Verify the fluid level. Repeat the bleed procedure if necessary.

I have a 2008 hyundia sonata. The ESC off is shown on my dash. What is my problem. The ESC off will go away.


There is a panel of switches to the left of the steering wheel. The left most switch should say "ESC OFF". Press it and it will be turned off. See pages 2-13 and 2-14 of the owners manual:

2005 Hyundai Sonata. Rear wheels very HOT


Did you remember to release the e brake?

Sounds like brakes hanging, foot on brake, or something that causes brakes to be on all the time, at least a little.

Yes this will damage everything that you described..and more. Brakes will work poorly...

Cannot find the parking brake adjuster to remove rotor on a 2008 hydai unsonata


The parking brake adjuster is located at the base of the parking brake lever. It reqires a deep 12mm or 13mm socket to acsess the nut. Pull the brake lever up enough until you see the bolt and nut.Then back it off counter clockwise until it's almost at the end. When you are ready to retighten the emerg. brake, pull the lever about two inches up and tighten the nut back down again. To test the adjustment. release the lever and make sure you can turn the wheel easily. The park lever should only come up about 3-4 inches to full stop.

Whistleing sound on golf gt tdi


It's probably the turbo you're hearing. They spin very fast and make a noise like that. Ever hear an 18-wheeler go by you and accelerate and they make that high-pitched whistle? That's the turbo spooling up. Now, if it sounds like a dentist's drill, that's usually a sign that the turbo is failing, but I'd bet that since your car is under four years old, as long as you've kept up on the maintenance, it's the normal turbo spool.
