There is an overflow hose from your rad cap mount that goes into the overflow tank. When the rad cap fails to seal or your engine overheats the pressurized water flows through the hose into your overflow tank. That is why you don't see any seepage from the rad cap.
Stay Calm, Be Brave, Wait for the Sign.
