Most likely while you are in there it's time to replace the hose. Saves having to go back if it starts leaking on the other end which is highly likely given the age. There should be a return heater hose, it is probably in similar condition. Diagram may be available via google. Youtube may show you how to. A very bright led flash light will allow you to see and trace the heater hose. You'll need to drain the radiator save the antifreze if new. Replace if old. Any other cooling system hoses need to be replaced? How is the water pump. It's not the leak is it? Otherwise Library probably has repair manual, or may be time to invest in repair manual. Lightly used may be available on Ebay and others. New hoses are cheap insurance against possible failure.
You will likely need the heater hose junction (Volvo p/n 3522035) since it always leaks and it connects the heater core to the heater hoses on the firewall. The kit usually contains the retaining clips, but not the O-rings to connect to the heater core. You will also need the outlet and inlet hoses (9186847 and 9186849). The length, angles and configuration of these hoses will help you understand their orientation in the engine bay. They can only go on one way. Else, they won't connect to the pipes from the engine.

Your car is overheating because you did not bleed the cooling system. The hanging hose may be the overflow drain. Unbolt the coolant reservoir, and raise it as high as you can. Start the motor, and add coolant until the heater starts blowing heat. You will see air bubbles in the reservoir until all of the air is out. This is a common procedure when doing any cooling system maintenance on Celicas.
