Take the radiator overflow tank out of the rig and wash it out. Most likely what you're seeing is not coolant but crud/rust in the tank.
If that's not the case, then the radiator is not sucking the overflow coolant back in when you cool down. This can be caused by a bad rad cap or a plugged or leaking pickup tube.
