Dumb Coolant Question?

[burtonbrd138]

This may be a really dumb question but I honestly have no idea. How much radiator coolant should i put in my truck, should it go above or at the cold fill line? I dont have the owners manual so i dont know

Add enough fluid so that it is just a bit above the cold fill line. If your cooling system is 100% empty, then be sure you keep checking the level as the radiator and motor works air out of the coolant passages

i have ran that with the coolant resevoir empty filled it at the cold fill line and over three days it sucked it away. Is that normal? if i fill it up again in might not do this?
