So I noticed the longer and hotter my SS gets it starts to leak coolant from the drivers side. So i got underneath and noticed it was coming from the upper radiator hose where it hooks to the radiator. So replaced the hose and got a heavy duty clamp. STILL leaks, only after the car has been running about 15 minutes and is hot.

Any suggestions, im getting tired of spilling coolant everywere.

you may have the plastic on the radiator scratched and that's why it's leaking, or check for it being dented. if you've ever used a razor blade to cut an old hose off, chances are the plastic neck is scratched. You could try sanding it smooth if you find the scratch, or just clean it good with alcohol then apply a thin even film of RTV around the plastic and let that cure before installing the hose.
I use hercules megaloc multi purpose thread sealant on a lot of stuff, if you can find that at a local plumbing store i bet that would get the hose to seal.

I would also double check you don't have a small leak in the radiator near the upper hose, had that happen on my truck
