ol' slant is dead... need help!

the hose was fine as well as my fluids when i left my house, the anti freeze flush "T" cracked along the way and since i was driving i didn't notice anything wrong till i heard a ticking. after i stopped and checked i drove not even another mile then replaced the hose and the anti freeze. after that i drove a 1/4 mile with not much heat then decided to trailer it back home. i didn't purposely drive with no anti freeze.
