I took my van to someone that gave me a very quick temporary fix. I believe they capped where the drain on the expansion tank goes back into the coolant system. Unfortunately I have looked almost everywhere under the hood and can not figure out where it is supposed to go into the system. So now when I drive, every time the radiator cap burps, i lose that fluid as it drains out of the bottom of the expansion tank. Can anyone advise where the drain hose connects to the system?

The radiator cap has one hose under the cap that goes to the expansion tank. There is no connection there for another hose as with many vehicles.

Thanks for any help that can be given
