Other than taking all the necessary steps in avoiding a catastrophe, make sure whoever is doing the work has some experience, having done this job before and knows exactly what they're doing, EVEN at dealer level. Ask questions at the service desk, request a technician who has done the job before and that has a good 'come back' record. Also, I highly recommend that you do the water pump, tensioner, idler and serp. belt. Using OEM parts and having GM do the work will get you 12 months warrenty on the parts and labor.

How do I know this? Well, it's one long sad story and I think the dealer just wants to put this all in the past, as does the mechanic. In all fairness, mistakes happen, they treated me fairly and I'm more than happy with the outcome,........and wouldn't need any head work for some time.

My 06' sedan has been a wonderful little car, 105,000 km now, it's been across N. American and back, and has been flawless. So far it's been both headlight bulbs, one tail light bulb, wiper blades, one set of tires (Falkin 205/50-15....not noted for high milage), loads of A/filters, oil/filter changes and then the big one......the timing belt and a major tune up. Would I buy another? You bet! With Flakin tires? You bet, that's the fun part.
