my tensioner shock absorber bushings have been worn out for a while. Today the upper mounting bolt fell out and the shock fell into the fan. Is the shock really required? will the belts fly off or something? BTW, I can't believe how much noise that shock was making at an idle. Sooooo much quieter!

It doesn't matter if you know what you're doing, as long as you look like you know what you're doing.

Yes

Without a damper, you increase vibrations along the entire belt. The belt is like a big rubberband.

Every time you add a load to it (turning, flipping on the headlights) you risk increased vibrations.


I wouldn't be too concerned driving without it on a beater, just keep some tools handy so you could put the belt back on. It would probably be a rare occasion.

However, the tensioner and the belt will wear out much faster.
