My 96 Lexus ES300 is making a squealing noise, I think its the main belt. The belt is not cracked or worn out, in fact it is fairly new, any ideas on how to stop the squealing noise?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Tamara, Your belt may be adjusted too tight causing excess tension on your belt in certain instances. You may want to ask your mechanic to check on the tension per manufacturer's specification.

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube It could be that the white writing on the belt is causing the squeeling. Also check the tensioner for the belt to make sure it's okay

Laurie Sarno, Co-Owner at Super Girls Auto Hello Tamara- you should check all pulleys, serpentine belt tensioner, water pump & timing belt idler & tensioner & alternator for bearing issues- these will often cause squeals - hope this helps- thanks Super Girls Auto.

Pat Fleischmann, Director of First Impressions at Community Tire Pros & Auto Repair Tamara.. As always, just looking may not show the exact culprit of the issue. It could be the belt tensioner needs adjusting or a bearing is out. The V-Belt or serpentine belt could have a glaze on it or the pulley could be going out. The problem may not even be related to the Belt. Take it to your trusted mechanic, you*ll be amazed how quickly they can have an answer for you and you*ll be on your way! Good luck and I hope it*s only an adjustment.
