Coolant Leak

[Sarv34]

Hey fellas I’m new to this forum and was torn on which topic I should post this question in. Okay as you can see I have a leak.. I drive a 2002 Chevy 1500 4.3 V6 4x4. I have a coolant leak the size of Texas underneath passenger side directly above the starter and right below the furthest back spark plug on passenger side. I am stumped. Is that head gasket or lower intake or, or, or? My question is how do I figure out for sure what is causing this leak? I’m not the most advanced mechanic but usually if I can take something apart I can put it back together with the help of asking questions and YouTube. (Lol) I appreciate any help I can get from you!
