Yes. A vehicle can be driven with the belt squealing. Since a mechanic with a wrench and a crowbar can fix it in 2 minutes, I have no idea why anyone would tolerate it!
A worn belt A worn bearing on one of the accessories driven by the belt A worn-out belt tensioner If the vehicle is an older one and does not have a spring-loaded belt tensioner it may also be just a loose belt.
A worn belt will cause a squealing noise. The squealing noise is caused when the belt slips. Tightening the belt will temporarily fix the problem.
Check all belt driven accessories to see if one has a bad bearing or is binding
I would replace them, There probably worn out. Once they get alot of miles on them they get a coating also that makes them squeal.
"Squealing" is usually from the belt or brakes. use belt conditioner to stop a squealing belt.(usually sold at walmart) you can probably figure out how to stop squealing brakes. but if not they need to be replaced. people need to start reading those owners manuals the car comes with.
The air conditioning compressor is driven by a belt. Check the tension on the belt. If there is more than 1/2 inch of play in the belt, tighten it.
Replace the belt.
The belt has worn on the edges and creates friction which causes squealing. Also, sometimes when a belt is cold it will squeal.
Nope.
Change the belt
PUT A NEW BELT ON IT
Worn serpentine belt? Bad bearing in belt driven accessory; alternator, idler pulley, a/c compressor etc.
