A new surge tank may fix the coolant light, about $70 online or eBay, about $250 at the stealer. Try Bar's Leak for any minor coolant leaks.

It was a factory additive in the older Northstar motors and improves newer motors as well. It can be found in auto parts stores or hardware stores. Use the liquid or pellets.

Yes they do clog things up like small leaks. That is why GM sells and uses them. They exist because they fix leaks. Just follow the directions because the pellets breakdown to very small particles and seal the very small leaks. If you have big pieces left, then the wrong product was used or the product was not used as directed.
