It's currently July in Atlanta and have noticed, over the last week or two, that I smell antifreeze coming from my 2006 Commander 4.7 after driving it.
As of this writing, the car has 89,000 miles and is approximately 6 years old.
I was able to take a look at it today -- I took a video in the spirit of both gaining insight and sharing this with other owners who may be encountering the same problem.

I noticed some moisture around where the upper radiator hose meets the engine block. It also looks like the spray pattern in concentrated in that area as well -- I do not see any sort of residue elsewhere in the engine, with the exception of some at the lip of the overflow tank.
I'm thinking it may just need a new upper radiator hose, but took the video to help diagnose.
Also, when reviewing the owners manual -- it's recommended that you replace the coolant at 6 years or 102,000 so, based on the age of my car, I am due for that.
As far as next steps, I will replace the upper and lower radiator hoses (and, of course, the antifreeze). I will do some research as well, but if anyone can share what other coolant hoses that they have replaced around this time -- that would be appreciated.
