Another way to check is to pull the manifold and look in the ports. Another way is that you will have a blown head gasket, usually between 1/2 or 3/4. That requires a comp. check. Mine was leaking out an ex. port and I found out from the guy behind me-and the fact the rad was stone cold after driving some distance. A can of Bars leak pellets and still no loss of coolant. There are smarter people who will chime in here but those are some things to check.

There is a third way to loose some coolant. If you fill your radiator with the
same amount of coolant each time, like a quart or so, it will kick it out through the overflow tube until it seeks the level it likes. That is the way mine does and others have said the same. Hope that is all that is happening.
