Cold start - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Every time I start my ZL1 up when it's cold, there is a noise coming from the supercharger. It only lasts long enough for the engine to warm up. I have been told that this is normal operation. This is my first time having a vehicle with a supercharger, so I don't really know what to expect.

Do I make an appointment with the dealership and leave it with them over night or is it normal operation?

Thanks in advance for your expert advice.

Can you discribe the noise? How cold is it in SC this time of year?

swizlstik · 01-09-2013, 09:09 AM

The noise sounds like bearings for the rotors in the SC. It's always started from being in my garage, so nothing less than 55 degrees.

Is it a rattling sound? If so, it could be the coupler which has a spring in it that rubs on the pulley shaft. Mine does it all the time. If so, it can be fixed, but not by the dealer as it requires an aftermarket part to be installed.

I have that rattling sound all the time, even when warm. Obviously the sound gets louder with more RPM's.

You can always make sure by going to the dealership for a proper diagnosis. Please let us know the outcome, regardless.

Exactly what I'm doing at 7:30am in the morning. Leaving it with them overnight.

This is jacked, Brandon, why is it that GM will not take care of this for us, yeah it doesn't cause a real problem for the engine but those of us that own the ZL1 and those that own the CTS-V have been complaining about this for years literally. In the beginning GM lost how much money replacing SC'er on the CTS-V's because of it? How much longer before GM steps up and decides to start putting in a part that doesn't make a ton of racket that will also make the customer happy?

Every vehicle concern is addressed on a case by case basis. We cannot say that just because there is a concern on one brand of GM, it is all across the board for all vehicles. Are you currently having a concern with your vehicle? If so, send me a brief description to my inbox.

I look forward to your reply.

Except it is. You're better off not saying anything than trying to speak on something you clearly know nothing about. Cadillac owners and Chevrolet owners have been complaining about the same thing... On the same engine...

And this has been adressed and explained before, countless times.
