Where is the heater hose located on a 1993 Chevy g-20 van?

On a 1993 Chevy G-20 van, the heater hose is typically located on the engine compartment's passenger side. One hose runs from the engine’s water pump to the heater core, while the other returns from the heater core back to the engine. You can follow the hoses from the firewall, where they connect to the heater core, to identify their paths. Always ensure the engine is cool before inspecting or working on any hoses to avoid burns or injuries.
