How do you figure out what hose is the heater hose or coolant hose on a 1996 Z24 cavalier?

Answer:

There are 2 coolant hoses. They are fat. They are attached to the top of the radiator and to the bottom of the radiator. Then there are two heater hoses on this model you can barely see them. They are alot smaller and will be underneeth the exhaust manifold. They are connected to the heater core at the firewall and the water pump housing tube and the coolant outlet adapter. The one on the coolant outlet adapter is the only end you can see without any trouble.
