Coolant in radiator doesnt stay full

[impulse001]

Like it says, I fill the radiator, after driving for a little it goes down a few inches and goes into the overfill tank. If I fill it again, same thing happens. Is this normal?

no, is it smoking? milky colored oil? heater core leaking? there could be alot of things, prolly just a leak..

Look at ALL the hoses. Especially the little ones, this happened to me a "few" times. They get little tiny pin holes in em.

Wait, isn't excess coolant supposed to go into the over flow tank?

Are you actually loosing coolant from the entire system, or is it going from the radiator into the over flow bottle, then escaping the over flow tank?

If the over flow tank is full then the radiator wouldn't be low.
