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

Check the two inch hose that connects the oil cooler to the egr cooler. It is down in the valley on top of the block on the passenger-side off the back of the oil-filter base. The hose is either orange or blue. The orange hose is prone to leaking and was replaced by the improved blue hose. If you have coolant in the valley beneath this hose, it could be your problem.

However, it would not cause white smoke. White smoke (beyond visible smoke during normal cold temperature start) could be a symptom that your EGR cooler is failing (leaking coolant into your intake manifold).

Check to see if the "valley" of the engine is wet. Look at the top of the engine just ahead of the oil fill tube. You should see a blue or orange hose that is close to the passenger valve cover mid way. again, just ahead of the oil fill tube. If it is leaking there you will need to replace that hose w/a blue one.
