SOURCE: A high pitched whining noise in the engine.

This Noise Description sounds Indicative of the Sounds that come from the Serpentine Belt Or Related parts such as Belt Idler Pulley or Belt Tentioner witch also has a Pulley, but if Tensioner itself is Literally BROKE I've replaced a number like this it will cause a Whining noise . Best case scenario its just the Belt, and if any of the other Problems turn out to be the Culprit the Belt MUST be Replaced Anyhow as Damage is Being caused By the Very Whining you hear.
PLEASE Spend the Extras $ for the BEST BELT as this Drives your Water pump, Alternator, A/C Compressor, Power Steering Pump All Crucial to Control of, easy Steering ,All Electrical-Power Distribution, The COOLING of Engine << VERY CRITICAL Component
The Pulleys usually have a more Hum type Whining. So I would say at Best The BELT , And WORST Belt Tentioner is Broke

SOURCE: Whining Noise

Hi, this sound is most likely coming from the power steering pump. I would first, check the power steering fluid level to see if it is full. if its not at the full mark, add some fluid. If the fluid reservoir is full upon inspection and the whining continues, the pump may be damaged and the pulley on the power steering pump could be slightly out of sync with the pump housing.

The second issue could be belt slippage. i would do a tension check on the drive belt and pulleys as well. make sure there isn't any ware and tare on the belt and make sure the tension is to specs.

Please rate and god bless:)

SOURCE: 97 GMC Z71 4X4 Not Locking in

If it's a shift - on - the - fly 4wd, then call your local Chevy truck dealer. There was a recall on the Electronic 4wd on these trucks. (common problem). Try this just for the heck of it. With the truck stopped, put in 4hi/lo, then put it in reverse. Back up slightly, (about 5ft or so) and then put it in drive (or first in a manual trans) and go forward. Did it lock in? If it locks in but won't unlock, try backing up to unlock. Hope this helps.

What is making this 08 caliber 2.0L sxt cvt have a High pitched whining sound at idle and driving?


Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one

High Pitched Whine


A high pitched whine like that indicates a bad bearing. Water pump, power steering pump, accessory belt slipping, alternator bearing, or in the worst case scenerio, Transmission pump.

Continued battery drain and high pitched noise when car started


Maybe the alternator is bad. A high pitched whine could mean that the alternator is not working properly.

One can test, by removing the belt to the alternator and running the engine and seeing if the whine goes away.

95 gmc sierra k1500 4x4 5spd manual noise


the leak is probably a separate issue from the noise. is the leak very bad? can you tell if it's engine oil or transmission lube/fluid? most likely the rear main bearing seal needs replacing. the noise is most likely the clutch release bearing. you should replace all components of the clutch assembly which include; clutch plate, pressure plate, release bearing and piolot bearing. also have the fly wheel resurfaced. while the trans is out, you can check the rear main seal and the trans input shaft seal and replace accordingly.

I have a 97 gmc sierra w/ 5.7 vortec...the problem is, it turn over but wont start. had the fuel pump changed less than a year ago. also changed plugs less than a year ago as well. i know its a broad range...


Stand near the back of the truck and have a helper turn the ignition to 'ON'. The GM fuel pumps make a very loud, high-pitched whining noise, you will know if the pump is running or not. If not running, check fuses, could be fuel pump relay as well.
