I have a 2012 6.2 supercharged cts v I know I need dexcool and ASAP but I’m not to sure witch one it is because there is two a clear tube with a cap that says dexcool on the passenger side of the engine and on the right side of the engine there is another dexcool that is in a black non see through container that says dexcool aswell. I’m not to sure where to refill it if someone can help out and explain I’d really appreciate it. Thanks

The black non-see through container is part of the main cooling system for the engine. The other see-through one behind the supercharger is part of the intercooler/supercharger cooling system. Hope this helps!

Do I put dexcool in both? Or do I just put it in the black non see through one?

Both.
