Question about 1991 Buick Park Avenue
The noise comes from the crankshaft pulleys.But get the belt checked.
If your car is making a squealing sound and you have checked all of the belts, then there is a good chance that either your AC Idler pulley bearings are gone, or your crank pulley is going bad and starting to separate. It is easy to determine which one it is. Just pull off the AC belt and then drive the car around. If the squealing didn't go away, it's the crank pulley.The crank pulley also acts as an engine dampner. This is accomplished by the rubber in between the pulley. Once the rubber wears out, the two metal pieces start to move independently. This is where the squealing comes from.
It's very important to change the pulley as soon as it starts making noise because if the pulley separates, you will lose all of the belts and possible damage your oil pump cover. Get the pulleys checked and replaced,which ever is checked faulty. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation
