I recently had a gm starter put in at the dealership. (Apparently all c5 gm starters are now remanufactured). Car starts fine now. However, there is a small “spinning”, kind of a slight “zinging” noise just after start up that lasts only for a second and goes away. It’s NOT any type of grinding noise.

The dealership agreed that it sounded weird but that everything was working properly. They ultimately warrantied and replaces the starter TWICE. All three in total have the exact same noise.

Has as anyone ever come across this issue? Or does anyone have a recommendation for me of what to do? Dealer actually said they would warranty it one more time. I guess I could try another brand starter but AC Delco seems to be the best aside from this issue. Thanks.

The dealer explained that it’s somethinf that is still touching the flywheel after the car starts. But it’s just very unusual that the same noise is there with three different new gm starters. Is Bosch a good brand? At this point I think I’ll have try an aftermarket starter. That zinging noise is annoying. And like you said, you pay dealer prices, you want things to work like stock.

Thanks. What is the benefit of the one longer bolt? Vibration?

Thanks. Was there a gm tsb on this?

Ok. Thanks. Still trying to figure out how to fix this noise issue. Looks like some people had the issue with the Bosch starter too.

Thanks. Any idea why here would be no noise with original starter but the zinging noise starts with the replacement? Thanks.

Ok. Thanks. I’ll ask the dealer if they have shims.

You would think that a gm replacement part would fit perfectly and not required any modifications.

Please post the link. I looked at rockauto. The one I saw was reman.

Thanks. I was looking if they sell shims. Hopefully this will fix the problem. Something still is hitting the flywheel after it starts.
