If there is rust coming around where the pulley is i would say the bearing is bad in the clutch but it would be making allot of noise the other problems could be the idle pulleys or the tension pulley i have 108 k miles and still have my original serpentine belt if the belt is bad it will start to look shiny like it has a glaze on it and pieces of the underside of the belt will be coming off Haynes repair manual says pieces broke off more than 1/2 inch or bigger on side with groves might need to be replaced . the idle pulleys can sound like the power steering is bad and making a whining noise if you turn your steering wheel and the noise is present check out power steering pump if you rev the engine and it whines more check the idle and tension pulleys hope this helps

I have a 99 ford mustang gt 5 speed and I had turn the temp. to cool and turned on defroster and had a real bad burning smell I pulled over and it was smoking around the belt what could this be?


I suspect that the clutch bearing on your a/c compressor is failing. This would cause increased resistance to the spinning motion induced by the serpentine belt. The belt then continues to travel around the pulley on the a/c compressor, but the pulley doesn't spin and creates added friction on the belt. After a brief period of time, the belt heats up to the point of smoldering and begins smoking. When you select "defrost" you are engaging the a/c compressor clutch just as if you selected air conditioning. Take your car to an automotive repair professional for replacement of the a/c clutch bearing or, if the clutch is severely degraded, replacement of the a/c compressor. Good luck.

Can i use a smaller serpentine belt if i bypass the air conditioning unit?


In some cases this can be done-but you do not mention the engine you have-also, there are bypass pullleys that some sellers have for just such circumstances, google bypass pulleys for your engine-you sometimes can do this yourself if you keep in mind the rotation of all pulleys has to remain the same,

It sounds like your air conditioning compressor or air conditioning clutches have gone bad the solution is to have rebuilt (or buy a rebuilt)air conditioning compressor. Do not attempt to work on thr compressor yourself unless you are certified in air conditioning, gas in system can kill you if you breeth it in.

Loose air conditioner component may break and


The only air conditioning component I can think of which could cause the serpentine belt to break would be the compressor. If you look under the hood you can see the belt winding around several pulleys of engine parts. The air condition compressor is the part which has two hoses with metal fittings and a wire harness attached to it. When the engine is on the pulley attached to the compressor should be rotating at the same speed as the other pulleys. Keep your hands, clothing and jewelry clear of all moving engine parts. If it is moving at the correct speed it is good, if it is not moving correctly it will cause the belt to slip creating friction until the belt breaks. Once the belt breaks the engine cooling, power steering and battery charging will stop, which will quickly cause the engine to stop working. This could cause engine damage, but it will defiantly strand you with a broken vehicle. If the pulley is working and the air conditioner is working, do not worry about it, but you may want to check the belt with the engine off for cracks or damage. If the belt is slipping and the air condition is not working, the vehicle will need a new compressor, coolant, and possibly a dryer. This could set you back about three hundred dollars. If you do not want to fix the air conditioning and the belt is not slipping run the vehicle as usual if the belt is good. If you do not want to fix the air conditioning and the belt is slipping you may be able to bypass the compressor and use a smaller belt.

High pitched howling and screeching (yes two different noises). The howling appears to happen when the air conditioning compressor pulley engages. The screeching, my guess would be from the belt. Any...


When the AC compressor kicks on, an electrical load is placed on the alternator and the drive belt that turns the alternator pulley, if not tight enough, can cause the belt to squeal. Replacing the belt should help with that noise if the belt is stretched from wear. The screeching noise can be from a bad idler pulley, a bad belt tensioner pulley or a bad alternator pulley or a failing clutch on a very old ac compressor and rarely a water pump pulley. To check pulleys remove the drive belt and turn them individually to see if they can be tilted up down or sideways with play in the "bearing" of the pulley. Also, you may wish to visually inspect the clutch on the ac and look for melted black rubber around the bolts that secure the clutch to the compressor (stinks,smokes and melts these rubber areas if ac compressor clutch fails).

Rattling from the engine when I start the 2006 V6 Sonata


Do you have the air conditioning on when you hear this rattle? If so, it could the clutch for the a/c compressor. You may also want to check the status of the idler pulley on the serpentine belt. Hope this helped and best wishes.

You answered your own question? Fix the compressor! What state are you in? Do you need A/C? if not, bypass the a/c and use a shorter belt, if it does not interfere with anything.
