They disconnected the hoses because they didn't want to put a new heater core in it. When you hook them up, you will either get a wet floorboard or your windshield will keep fogging up. If you want to restore heat, you will have to put in a new heater core and then hook up those two hoses. The one coming from the intake manifold goes in the left side(driver's side) of the heater core. The other one is the return line and it goes to the water pump. BTW, that is antifreeze in the hoses and it is supposed to be there.
