timing belt age as a sole replacement indicator

[Grant Lenahan]

Rubber dry rots.  So yes, age is a determinant as well.

But i’m fairly convinced that the belt itself is rarely the issue in our cars.  More often it is a tensioner or water pump that is failing, placing more drag not he belt, and then poof.

That said, after 8-9 years, although i will only have  50-55k on my belt, I’ll do another nose job on my C5
