Little help please

Just started truck and noticed antifreeze running out. Pulled front grill and see that the antifreeze highest point was coming out of first picture. Had front end apart last weekend replacing lights and grill. Never touched this part. Shut truck off restarted and nothing??

 

Not sure if related other day driving heard a whining when under load. Super cold out stopped put in park rev engine no noise, put in drive whined a little more while moving under load but went away Farley quick.
Any help would be appreciated thank you!

 

This is how much came out.

 

Hows your coolant level?

 

Where is it leaking from? I see an AC condenser and transmission cooler.
Are you sure it is coolant?

 

Overflow is low….. my antifreeze is pink, liquid running out was greenish in color and had antifreeze smell I did wash my truck before coming home it is 12 degrees here, sat in heated garage a good four hours before I went out and worked on it. Gonna top of reservoir and keep eye on it. Really odd it was coming out transmission cooler coil right under AC condenser line.
Any chance I froze up a bunch of detergent from auto car wash?doesn’t seem likely to me but I’m at a loss.
Thank you for the replies!
