How can I repair/stop a coolant leak from a bolt in front left side of engine?

What is your question?

In my 2003 Dakota 3.9 L V6 , I have coolant slowly leaking from one of two bolts left side, front of engine near crank pulley. I had to add 1/4 gallon coolant to my overflow 06/09/17. Then again I added coolant on 06/16/17, when I noticed a leak under my truck. Today(06/17/17) it leaked again and added coolant.
