2017 Sierra - chatter or squeeling from front of engine


Recommended Posts

Today while idling, I noticed my 2017 GMC Sierra All terrain (5.3) has a chatter while idling. I revved the engine and the noise doesn't get louder. I popped the hood and it appears the noise is coming from the front of the engine near the belt area. Do these trucks have issues with tensioners or does anybody have a clue what it could be? Possibly the water pump, or tensioner? anybody else experienced a noise or chatter/squeak?

 

I am really regretting this purchase as it appears this truck just keeps having issue after issue. Noisy rear leaf springs/clunky transmission, now a chattering engine... absolutely ridiculous and very frustrating
