Hello All....long time lurker hear and I appreciate picking up tibits hear and there. Now I have an issue I cannot figure out. This weekend I lost what it looks to be a guide pulley on my SC serp belt. Bearing seized up and the plastic pulley pretty much shredded off. Cut the belt off so now I'm running w/ no SC.

My question is two part. I cannot ID the pulley on Rock Auto or GM Parts Direct. It's the one which is just across from the motor mount on the passenger side fender and looks to only be a guide pulley. Second, how hard is it to change this since it looks to be in a tight spot with the motor mount right there and what kind of bolt holds it on; torx bit, hex etc.

Any help is greatly appreciated.

That would be pulley #9 on the Dayco website picture.

To swap that pulley you need to put a jack under the oil pan with a piece of wood for cushioning and then remove the passenger side engine mount. This is done by removing the body side mount, then the motor side (E torx bits to remove the studs from the block). The pulley is then easy to access.

While you are there, check the water pump.
