Coolant reservoir keeps leaking

Leak is coming from here



In the attached photos, I can see that the leak is clearly coming from here. Before I take it into the mechanic, I wanted to ask this knowledgeable forum of Chrysler members if they might know which part of the coolant system is leaking, so I can know what part to tell the mechanic the coolant leak is coming from, or so I can maybe research how to replace the leaking part myself? Any knowledge or input would be greatly appreciated?

Thank you. My Sebring 2010 is at 212,000 and I dont want to throw in the towel with her just yet. Any responses about what the leaking part might be, would be very much appreciated

Thank you

 

There are dyes that you can buy to help you trace a leak. Some are visible under UV light. You might need one of those "black lights" that people use at dance parties. Search the web for coolant leak detector.
