On a 1993 Chevy G-20 Sports Van, the heater hoses are typically located on the engine's firewall, connecting the engine's cooling system to the heater core inside the cabin. One hose comes from the engine block or intake manifold, while the other returns from the heater core to the engine. You may need to lift the hood and look toward the back of the engine compartment to find them. Always ensure the engine is cool before inspecting or handling the hoses.
