My 2001 XKR convertible has 77K miles on it with the original drive belt. The belt does not show any obvious signs of deterioration or cracking but in reading a training bulletin on the XK8 ( I believe) it indicates there are tension marks on the front of the engine to measure the stretch of the belt and when to replace. I am not getting any slippage or squeals.

I tried to see these marks but could not locate them. Does the bonnet need to be removed in order to get a good frontal view of the lower engine? What is the average life of the belt? Car is now 13 years old but not a lot of mileage.

Hoe difficult to replace? The training bulletin did not show a supercharger, which I have.

Thanks

If it indeed is the original belt I would change it. I forgot what I paid for mine (XK8), but it was only about $50. Took me maybe 15 minutes once I made sure I knew how it routed.
