My guess is the o-ring is shot.
Our Montes use 2 plastic elbows. But some other 3800 Series II engines used 1 elbow (as what we have as a 2nd coolant was originally a cast aluminum 90* bend on the belt tensioner assembly the elbows connect with).
I can do the elbows in about 30 minutes, then add coolant and bleed the air. The process is quite easy. As a tip, I use just a touch of lube (like WD-40 on my finger) and run it on the outer edge of the elbow connections (to help the elbow seat properly and prevent the o-ring from moving).

Dex cool around the T-stat could be a T-stat gasket fail or:
Get the pressure tester, it's a free loan-a-tool from most parts stores. Easy to use and will hopefully help you pin point the problem fast and easy (if not you will have to start pulling things apart). It's the best first thing to try for diagnosing.
TB gasket, UIM, UIM gasket. Even with a pressure test, tough to tell without taking it apart.
