Tensioner

"The groove on the block" - don't quite understand that. The tensioner arm is on a big allen-headed bolt. Has that bolt snapped? If so you'll have to remove it and buy a new bolt (I've actually got one if you want one)

Or has something else snapped?

Replace the damper if it's shot. They tend to rattle when the top metalastik bush breaks up. If the damper's still good you can put a rubber bush either side of the damper top mount, bolt it up tight and the rattle will stop

Check the idlers and bearings & replace any that are noisy when you spin them. Also think about replacing the water pump while you're in there. About £40 exchange from the dealer

You'll probably need to take the rad out and remove the fan to make life easier. Hope you haven't got aircon!

Sound like the block will need to be re-tapped and an oversize bolt fitted. Not familiar with this, whether a helicoil can be used.
