is the coolant coming from a bolt? or out the side of the gasket?

if its leaking at the bolt, take that bolt out, and clean the threads and put thread sealant on the threads and put it back in.

your 100% sure its not a plastic elbow? you got two, one you can see, and a lower on under the alt near the p/s pump. that one leaks down the fire wall side of the engine.
