Help coolant leak dont no where.

Well the rad is not leaking and i dont think a hose went bad.Well it looks like it is leaking from the bypass hose well there 2 things under the hose that look like there leaking not sure what there called can any1 help me out.The 2 thing look like metal/brass.It is a 92 cutlass supreme 3.1.Sure it not the water pump as it is only a few months old.This just started to happend a few weeks back.

Iam pretty sure now its not the bypass hose.Theres 2 brass looking bolts under the bypass near the t-stat.The bolts look pretty big 1 inch maybe.They go into the block any idea what they are?
