You need to climb up and lean over the engine and run your fingers around the back 2 corners of the intake manifold and see if you get antifreeze on them.
They are none for the intake gaskets to leak engine coolant. It is a common problem with the vortec engines.
There are also 2 freeze plugs in the back of the engine where the fly-wheel is bolted to the engine that could be leaking engine coolant.
There is also a heater core hose that goes into the rear left corner of the intake that could be leaking. The hose fits into a quick disconnect fitting that screews into the intake. It is common for the fitting to leak too,

Why is your coolant leaking?
You need to explain more on where exactly the coolant is leaking. There are several possible reasons why your coolant is leaking. If it's from your main hoses that lead to and from the engine or radiator, you need to check the condition the hoses are in. If they're in a decent condition, it's not that. If it's leaking around where the hoses are connecting, it's probably not tight enough, or there is possibly a clog in your coolant line. Also get your radiator checked. If it's leaking into the passenger compartment, it's most likely the heater core.

Leaking or loosing coolant? If it is leaking then where is the leak? If it is just loosing coolant with no apparent leak, then you more than likely have a blown head gasket or cracked head. If there is coolant in the oil, or white sweet smelling smoke coming from the exhaust you definitely have an internal problem. Serious engine damage will occur if you continue to drive this vehicle.
Why does my318jeep use oil no leaks no exhaust smoke?
If you aren't seeing oil leaking in the driveway then it almost has to be burning it due to worn valves or pistons. There most likely is exhaust smoke but you just can't see it yet. One other thing to check is your engine coolant. A leaking main seal will allow engine oil into the coolant side of the engine which will turn your coolant a milky white frothy looking liquid.

could be leaking from a head gasket and trickling down or your heater core is leaking and driping out of the condensation drain from inside the cab. most likely its your heater core. check the fire wall above the starter and look for that drain line. if it is dripping and is colored (green or orange) its coolant and coming from heater core. that's a bear to replace. good luck.
