Hey guys, in my 06 Ls2 I recently changed the harmonic balancer, reason being I saw it wobbling a good amount and decided to change it, no noises or anythings just the movement. Car drove fine then and still does today. Replaced the balancer with oem AC Delco brand. I was told that I didn't need to change the belts that they were fine. After replacing the balancer I then noticed a noise coming from the engine that I have never heard before. I don't drive it much, but the last few times I have the noise has gotten worse, especially when I step on the throttle just a bit. So I came to the conclusion to change the ac and drive belts, which comes to my question. I usually get the part number from the dealer and purchase the part elsewhere, hoping to get oem as well. Me personally, I'm a guy who likes to save as much as possible, but I will spend a little more to get the right part. So I got the part numbers for the belts and purchased them from a local part store. The brand is Gates Corporation out of Denver. My question is will these belts work??? Or should I take them back and spend a bit more on the GM belts??? I have been told that these are a good brand, but I have never heard of them. My apologies for the long paragraph and thank you very much in advance.

 

Gates are good quality.

If you are taking the time to do the belts, spend the extra 45.00 and replace the three idler pulleys.
Pretty sure all foriegn noises will go away.
