Radiator tank overflow

[mhavel]

I'm having an problem with antifreeze flowing out of the overflow next to the cap on the overflow tank. The antifreeze does not squirt out but rathers bubbles out. I don't believe it was overfilled so I'm at a loss as to why it would bubble out the overflow when it is actually low. Any thoughts. It doesn't start until the engine is warm. I though if I had a head gasket problem it would begin to bubble out immediatly. Any thoughts.

I had a simular problem there was an hair line crack in the tank. Replaced it. All is well!!
