Where is the upper radiator hose on a 1999 Geo Metro?

On a 1999 Geo Metro, the upper radiator hose is typically located at the top of the radiator, connecting the radiator to the engine's thermostat housing. It allows coolant to flow from the radiator to the engine when the engine is running. To access it, you may need to open the hood and look towards the front of the engine compartment, near the driver's side.
