The culprit is one of two old pinky sized hoses coming from the passenger side top rear of the engine (labeled "UT" from when the headgasket was replaced) to a double tipped screw in fitting just below the power steering pump.

Cant find it on a diagram. Any idea help on WTF this is? Im not sure if the fitting is leaking or the hoses.

Ill take a picture once it stops raining.

 

the double tipped fitting is the idle up for the power steering .. ive seen power steering fluid flow thru that into the intake but not coolant ..

 

damn. i guess ill keep digging then. the leak is definitely coolant.

 

The only coolant leak you'd have on that side of the engine is from the u-shaped hose behind the plenum, passenger side. REMOVE YOUR HOOD; you'll thank me later. It's only 4 bolts & one of the easiest things you'll ever remove/reinstall on your truck~

You'll find it right here (yes, I realized it's a right hand drive pic, not my truck):



Here's the little bugger:

 

PS idle up/air control valve. Has nothing to do with coolant. Opens to let air, from one hose to the other, into the intake when the pump pressure rises. This raises the idle rpm and helps keep the engine from bogging when the power steering pump pulley gets harder to turn.
