    What you are probably looking at is the clutch on the a/c compressor coming apart.

Renault scenic Auxiliary belt tensioner making high pitched noise


Time to replace the pulley, you can test it by pulling off the belt and spinning the pully with your hand or some compressed air, if it makes noise then its time to replace.

What would cause whistling noise near pully and belt area noise gets louder with acceleration


The engine serpentine belt may be worn or wet. The belt slips, causing a high pitched squealing or whistle noise. The other possiblility is a bearing beginning to go out on one of your belt driven components

I have a 1985 s10 with the2.8 5 speed trans when i let the cluch pedal up it makes a constant rubbing noise and a high pitched squeel and its all qieut when i shove the pedal down any sugestions?


Hi and welcome to FixYa, I am Kelly,
Your clutch release bearing (throw out bearing) has failed. The transmission has to be unmounted from the engine to change this bearing. (Just like a clutch job!) Being this is a 1985 vehicle you should inspect the clutch plate and the pressure plate for wear. The fingers on the pressure plate should be quite worn if the throw out bearing is doing as you stated in your post. I.e rubbing sound and high pitched squeel. Inspection of the clutch plate consists of making sure the rivets are still not even with the friction pad surfaces. Don't forget to also inspect the engine flywheel for abnormal wear while your working in this area.

Things you might need.... U joints
Transmission rear seal
Clutch Plate
Pressure Plate

Thanks for choosing FixYa,
Kelly

It is possible that you have a leak in your intake manifold... when the gas peddle is applied the manifold takes in more air and makes a high pitched sound because of the crack.

High dinging or ringing noise Under hood


if it goes away when you turn the a/c on its the a/c clutch plate that is dragging and when you turn it on its pulled into the the a/c compressor and is turning all the time that's why noise goes away,you have to replace the a/c clutch.sometimes you can try prying with a screwdriver the edge that is dragging and noise will go away.

I have a high pitched noise which appears to be coming from front right engine compartment (as you are looking at the engine) which sounds kind of like a belt that is squealing. It is intermittent. Just...


Could be several things. WHICH ENGINE?.. 4 cylinder (has three belts, power steering/water pump, alternator & A/C compressor, one tensioner pully A/C compressor), The V6 2.7 (has only one belt, 1 Idler pully and 1 tensioner pully), the V6 3.5 has two belts - A/C/alternator, and power steering - there are two tensioner pullys). Noises can be caused by the belt(s) themselves, pullys, bearings, pully bearings, water pump shaft bearings (or belts/pullys rubbing up against something). Let's not forget that there is also belt(s) behind the Timing Belt cover as well as pullys and bearings associated with the timing system. You could start by removing one accy drive belt at a time (alternator, water pump, compressor, power steering, etc) to see whether or not the noise goes away in each case. If after each case, you discover the noise is still there, it's probably behind the timing belt cover (idler/tensioner pully, water pump shaft bearing, crankshaft bearing, etc.). Good Luck

The car is making a grinding/knicking noise it is


pullys have bearings and the bearings will go bad. what you need to figure out is what pully is makeing the noise and replace said pully. another problem you might have is the power steering pump. check the fluid level to make sure it's not low or dry. when a power steering pump goes bad it makes some noise. another possibale problem is if the car has a/c. the a/c compressor has an internal clutch that will make a grinding noise when it goes bad. To test this start the car turn you a/c on or your defrosters on and listen for the noise in the lower front area of the engine compartment (usually the lowest front pully). shut off the car and look for metal shavings on the pully. for this you should take the car to someone to evacuate the system so you don't release refridgerant into the atmosphere (it is also very flamable) and will need to be oiled with 134a oil and recharged after the repair. hope this helps.

Whistling noise under the hood of my Honda civic.


Thhis noise could be a mutitude of issues. If you have some dash board spray, try spraying some on the top pully staying away from the fans and belts. Also position your face away from the expected spray. Water can be used but it not as affective. Then let me know what happened. Later DRRXR :)
