Maybe better images would work best. It almost looks like you're pointing at the intake manifold bolt unless you're talking about the freeze plug-esque item lower on the motor.

First off this belongs in the small questions thread!
I skimmed through my fsm for you but couldn't find much info about it. If you know it's leaking coolant my best advice would be to remove the plug, inspect the threads for damage, if it looks okay reinstall with sealant or Teflon tape and torque to 25 ft/lbs. Be sure to bleed the coolant system properly. Don't see why that wouldn't solve your problem, best of luck to you!

Looks like a freeze plug

Imo that does not look like a freeze plug
