Engine belts torn on 2005 c6
Hi all,
A few months back my 2005 C6 tore in a sudden it's engine belts, I think both the airco and the main belt. I had them replaced and within a month of the replacement they were torn again. The car is in my garage since.
Then a good friend of mine, specialist in Corvette, said he's seen a few times over the internet similar problem with early 2005 vettes and that it may be a common issue with those.
Do you know if that is the case and how do I cure it? Apparently just replacing the belts wont cut it, what else do I need to replace to make sure the car runs fine and wont tear belts for no reason.
Thanks for your help

A new Harmonic balance, an there have been lots of threads lately about this problem.
It is wobbling for sure but I think not severely.
It is an expensive repair to have done $1000-1200, but if you have skills then $250-500 depending on the damper chosen.
Try searching for "harmonic balance wobbling".

Thanks Boomer, indeed there are some threads, but since I'm in Europe, I have to order parts from the US and it's always best to make sure and be certain of what I need to order, because it's one thing almost nobody knows those cars here, but it's yet another there are no parts 
When I went to the GM dealer here they said they know nothing about this problem and have no clue what to do.
So I must basically make sure I get all the stuff I need for the repair at once and then just tell them (or my friend - unofficial corvette mechanic specialist) - that's it, replace those.
Do I need to only replace the harmonic balancer or the pulley and other parts as well? The balancer I see at around $175 online

That's strange, because the "wobble" you see is very common on all years. The first symptom of a problem is usually that the main belt starts producing a loud audible harmonic "chirp". And that is long before the belt actually fails. As far as replacing the harmonic balancer (crank pulley), i think you are barking up the wrong tree. In the 8 years I've been on this forum, I don't remember one case where a belt actually failed. Bottom line is that I'd be looking for another cause.

I'll repeat what I said: That's strange, because the "wobble" you see is very common on all years. And it's not bad wobble. Especially if it's not causing the belt to "chirp."

that's kindda bad for any mechanic to give a response like that
at least visually look at the car
seems like skilled workers and personal drive and pride are seriously diminishing in society as whole
sometimes.... ya gotta pull up the sleeves and dig in, and sometimes use a little muscle now-and-then

Yeah, it's common on all years because GM is using a defective part. Mine wobbled just like that too and the dealer thought it was bad enough to need replacing. If it's not causing the belts to chirp now it will eventually so why wait.

Your dealer probably needed the work. And the old adage still applies, "if it aint broke..." It'll cost the OP ~$1000 to change the balancer. The wobble is fairly normal, the belts aren't chirping but they are torn. Whatever that means. Again, I've never heard of "torn" belt and especially not both of them. Something else is going on here.

The dampener consist of a center HUB and an outer ring. They are BONDED together with a rubber elastomer. IF,,,,,,, the elastomer separates the outer ring will walk on the center HUB and that will cause belt misalignment/shredding.
Replace the dampener. You can order an OEM dampener or order aftermarket. I used Powerbond Dampener.
You will need a timing chain cover gasket, damper seal, antifreeze, power steering fluid, water pump gaskets, lock tight, new damper bolt (strongly recommend aftermarket ARP Bolt),, If you remove the Rack, (new O rings for the power steering hoses) if you damage them.
If you want a good deal on GM parts, contact Gene Culley or Patrick www.gmpartshouse.com
Its a good time to change out the power steering fluid and antifreeze with new DEXCOOL. Depending on how many miles on the engine, consider a new timing chain and chain dampener and new Melling high volume oil pump. Also consider a new water pump and thermostat on a high mile engine
Hope this helps.

Okay I thought over this exercise and decided I'll have the dealer do the job. A bit more expensive, but should be guaranteed quality + I get warranty. Harmonic balancer + new belts + work = $800. I think that was a fair price, just hope it holds better this time before new replacement is necessary.
