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.
The Chevy heater hose removal tool is a plastic piece that clamps around the hose. The tool slides into the fitting to release the hose.
There are two hoses that connect to the heater core, and they are located next to the brake master cylinder, on the driver side of the van. I believe the bottom hose is the inlet and the top hose is the outlet. Good Luck, Greg
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.
