2010 SS Loud Squeaking Noise with belts off - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a 2010 SS 6.2 Auto. It does have a Cam and a Supercharger and it has been running perfectly. I don't abuse the car at all. I haven't had any problems until today. I started it and it has a loud chirping noise. When you shut it off, it chirps for another second or so. I pulled the belts, expecting to find an Idler bad. I started it briefly with both belts removed and it still makes the sound. It does have good Oil Pressure. I now suspect a Lifter or a Rocker. The Cam was put in by the Prior Owner and I know the Lifters were new but I am not sure if he bushed or replaced the Rockers. Before I start tearing into it, I was curious what others have experienced

If it is still chirping after the engine stops rotating, I would be willing to bet on a bad cooling fan. I have seen in on many other models, but not a Camaro as of yet. Easy to check.

I do appreciate the reply. I have HP Tuners, which allows you to turn on each fan. I did check this first and it is absolutely not the problem

What's key is that you say the chirping continues for a second after you shut the engine off, even with the belts off. That eliminates everything in the engine.

I would be suspecting the HVAC fan, believe it or not. Make sure it's all the way off and try again.
