'07 GMC 5.3L coolant leak

[BrianDeTienne]

trying to diagnose the coolant leak on my '07 GMC 5.3L. I just replaced the w/p and gaskets...no leaks when I parked the truck last night. When I drive out this morning, I notice that I still have the same "puddle" under the truck after it sat overnight. It appears that I may have changed the w/p for no reason as I still have the same leak that caused me to change the w/p.

Any clues?
