Serpentine belt part number

Can anyone tell me the GM part number for a 2000 LS 3.8l standard serpentine belt?

Thank you.

12588411

Thanks

not a problem, you're welcome.

You might want to consider the Goodyear Gatorback belt for your car... It's advertised to last longer and run quieter than the stock belt... It's also called a Poly-V belt, P/N 4060915 for the 3.8L motor...
