Can't hear anything with a stethoscope 'cause everything is rotating and you can't get on it to locate a noise.
I have now a 1/2" breaker bar that should fit the tensioner, I think I was using a 3/8" which is too small for that square socket. And if the noise disappears if I loosen tension on the belt, what does that mean? It still could be a pulley or the belt or anything driven by the belt, so that's no help to locate the source of the whistle.
And now my HVAC light is no longer flashing when I turn the unit on.
Friggin car. But I should be glad that it runs well.
