Leaking fluid

Can someone be so kind and shed some light what i need to fix this issue.

 

Looks like pag oil with leak dye in it. Is your truck running pink coolant? It should be. But if it has been changed to green, then it could be coolant.

 

Coolant leak. Replace that part.

 

Its an a/c leak you need to evacuate the a/c system replace that seal, evacuate the a/c again and then charge it.

 

^^^This^^^ And make sure you use a seal made for the A/C system. I just replaced mine and I went to the stealership and picked them up, These are the weakest link in the system spend a little extra to get the right ones. just my .02.
