Leaking Coolant Need Help

Ok guys. I am leaking coolant from underneath the truck. I have looked all under the hood trying to figure out where its coming from. I dont think its coming from the radiator as far as i can see. Its not much about 2' x 2' spot on the ground every morning. The actual drip is coming from just behind the passenger tire and about 1.5 foot towards the middle. Any idea? Noticed the truck smokes when you first start it and cold starts seem to have gotten a little worse. 2004 cc sb psd. Stock

EGR cooler to oil cooler hose would be my first guess.

As mentioned check the oil cooler to egr cooler hose. That's normaly where this type of leak comes from. If you look in the valley of the engine and it looks wet that is your problem.

I have a slight leak now that its cold out also. Talked to cheezit, he said you won't always have wetness in the valley- which I don't. It runs along the side of the head and down the side of the block around the back of the starter on mine. I topped off the coolant yest, took a tiny bit, not even 8oz? So until it warms up a bit, I'll just keep an eye on it and keep the degas topped off (because its cold out, and I'm lazy lol).
EDIT: From the tech folder, here is the location of the hose in question. The blue one should be the one you have as the older orange leaked and was replaced by the blue http://dan.prxy.org/Truck/6L_bible_h.../Page_074.html
