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)

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.

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.

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.
