I HAD TO REPLACE THE TENSIONER PULLEY MOUNT
Horrible sound, A/C Tensioner Pulley needs to be replaced. A/C still works, as does heater. But it is about to go out (causes a grinding sound in front left engine area, that changes pitch when you hit A/C switch or heater switch)
Piulley spun wopperjawed. And threw sparks and belt started to come off.
Belt tension pulley froze up and broke belt. 60000 miles. New pulley and belt put on. 2003 Buick Regal LS
Belt broke on the car. Replaced the belt. High pitched squeal and the new belt was trashed. Then replaced the tensioner and belt, the car ran as good as new.
I had this problem and Sunset Buick in Sarasota replaced the belt and tensioner for $125. I had a $100 credit from GM due to low mileage on the car. This for 2.0 Turbo Engine.
It's actually a LeSabre, but same issue. Recently bought a used '95 LeSabre with 73k miles on it. Driven regularly, inspected every year, 1 owner. Makes a whining noise and the belt appears to be close to failing. I assume the noise is the tensioner pulley assembly. I plan on taking care of it next spring... the car can sit until then. Seems like it wouldn't be a terrible project, but not ideal in the cold weather we're having.
Belt would squeak put pulley tensioner.
Buick 2011 Turbo. When it's hot outside, car runs rough. Stabilitrak light came on twice but has not been on lately. When car is turned off, has whirring sound. Outside temperatures here in East Texas have been near 100 degrees lately. Does not happen at lower temperatures.
had to have it replaced because the belt tensioner was leaking. mileage may not be accurate l.e.d. screen doesnt light up
This problem occurred after a catalytic converter replacement. The first shop said that this would run me $385 to replace the Drivebelt tensioner as well. Luckily, I had another shop replace the pulley for $90 and it did the trick.
