Low Coolant Problem

My truck ('01 gmc 2500HD) has started to give me the "Low Coolant" light. I replace the coolant but it disappears some place I can't find. there are no leaks under the truck, even after 4 days. Also, there seems to be alot of air in the cooling system. Any idea? thks!

Chances are is that its pushing out the over flow. which would mean blown headgasket. I say this from recent experiance

If your pulling motor to do job and has high milage, you may want to consider doing and LBZ shortblock with cut LB7 pistons. and Head studs of course.
