When to replace Timing Belt

[Chevy Customer Svc]

I've read that earlier models, 2004-2008 or so, its 60K (some here recommend 50K), 100K for newer models. Early models are prone to rare belt breakage after 50K miles or so, later models not.

After checking 2008 Owner's Manual it suggests 60K miles changing the Timing Belt; and 2011 Aveo Owner's Manual suggests 100K miles changing the Timing Belt. I will pass along your feedback regarding making the maintenance schedule easier to interpret. Thank you for being a Chevy customer.
