Low Coolant Problem

mainediesel · #1 10-31-2009, 04:17 PM

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. -
