Coolant leak: bottom passenger side of radiator by sensor
It appears I have a coolant leak by the bottom passenger side of the radiator right before the main hose clamps on. There seems to be some kind of wire harness/sensor and the leak appears to be coming from that sensor. Anyone experience a similar leak or know the part number of this thing? See attachment...

too common. It cost me $125.00 to have it replaced. there is another temperature sensor on top of the radiator as well.

I got lucky and di not have to drain the coolant. I just left it parked in the garage for a few days until the part was ordered. Leave the Coolant Cap On! Do not open or it will release the coolant back into the lines and you will lose a lot. I was able to swap out pretty quick and only lost a few drops. You could also drain the coolant if you want, but it was not necessary. Either way, be prepared for a cleanup just in case. If you search there was a recent thread on this. I think it was started by Quarta2Six.

After some searching I see how common this problem is. I think I'll try replacing just the o-ring and see what happens. Thanks for all the good info and tips!
