yep, been a number of years but a loose fitting, hose clamp, or water pump seal will leak pretty good when it cools off and different materials have different shrink rates and i haven't put my head under the hood too often on my duramax so i don't know how many leak points there are but i'm sure you have at least two clamps & hoses and of course the water pump
