We replaced the fan belt in a 1994 Toyota 4Runner and there was still a loud screeching noise and it doesn't seem like the top pulley is turning.

Sounds like the pulley bearing is bad and has failed -- remove the belt and try and turn the pulley by hand. if it does not turn ' freely ' and smooth, then replace the pulley.

My toyota 4runner v6 engine seems to be stuck

Check the pulley behind the fan clutch, remove the belts and check for a seized pulley, the fan should spin by hand with the pulley.

My 2003 dodge durango keeps overheating , i just had new radiator put in and it started overheating again but now it is overheating with a very loud screeching noise like a belt sound what could be ca

as for noise will have to inspect under hood,could be fan or belt or pulley ,water pump .these are some things it could...My suggestion for overheating is replace thermostat. If your car has electric cooling fan then it may not be working..turn defrost on and if fan kicks on then fan motor is good..Now this does not mean that fan is working properly because fan is controlled by heat sensor switch that kicks fan on when motor reaches heat range......Things i would have checked....hope this information helps and good luck and Please rate my post...

My car(Tazz 2004 1.3) has a noise from coming from the left side of the engine(if u facing the car)that sounds like a worn fan belt,i went to a "mechanic" and he thought that it was the belt...

Still sounds to me like a fan belt noise but not necessarily the fault of the belt.
Either the profile on the belt is incorrect or worn pulleys or one of the units it powering (power steering pump/Aircon or alternator)may have a problem. Suggest to remove the belt and turn by hand/inspect every pulley. If anyone of them is hard to turn or has any resistance noise then that will be the problem not the belt. You can verify by starting the motor and running it for a brief time without the belt on to check the noise is gone too. Hope this helps. Thank you

There are 3 belts on the truck (1994 V6, 4wd). The belt that goes around the alternator was not spinning and there was a loud screeching noise. I cut the alternator belt to see what the truck would do with...

The pulleys may be out of alignment due to a bent or misinstalled alternator bracket. the alternator itself may be pulling so much current that the belt is slipping on its pulley. (might be why the other alternator failed. Check the battery voltage with everything turned off and see if you have a parasitic battery drain.) The bearing for the idler pulley (if equipped) could be failing.

The belts continue to make a loud screeching noises when i drive over 55. Sometimes when the car is idling the belts make noise. Could it be the tension pulley.

it could be the tensioner, water pump, alternator, A/C compressor, power steering, or even a really bad serpentine belt. The only way to be sure is to remove the s-belt and spin-check the pulleys and listen for squeaks or grinding bearings.

I own a 1995 Toyota Corolla and when I turn on the car and turn the steering wheel there is a loud screeching noise. This noise will go away after about 5 minutes of driving. Can I repair whatever this...

There is a loose belt, or a pulley giving you problems. Remove the belts if you felt that one of those belts was really loose that was the problem, spin the pulleys, the crank pulley is hard to spin by hand see if wobble by hand, if one of those pulleys has excessive movement that was the problem, if all of the are tight then just adjust the belt tension, good luck BettyHasting.

2006 Toyota Corolla w/VVT-I 16 valve with 66K miles - screeching sound from engine compartment, belts seem good.

hi, i know you say the belts seem good but one way to rule the fan belt or alternater belt out is to pour water onto the belt and if the noise stops then the chances are the belt needs tightening.
If how ever you still have the noise then this would point towards one of the pulleys bearings running dry you can try putting oil into where the bearing is its difficult to get the oil in their as their is very little gap so using a spray oil would be your best option.

If after doing this you still have the noise then your going to have to replace the pulley thats giving you the noise to find out witch pulley it is spray each one in turn with spray lube and see witch one makes the noise less and then this is the one that needs replacing.

Your power steering pump can give you the noise your getting if the fluid is to low so make sure you check all the levels ok.

Let me know how you get on or if you need further assistance ok

I have a 1990 jeep YJ replaced the alternator and now there is a loud screeching noise replaced the belt,replaced new bearing in idler pulley still makes a loud screeching noise?

If the belt is not tense enough it will squeal, so make sure it's tight enough. Otherwise you can use a stethoscope or long screwdriver up to your ear to isolate the source of the noise.
