* Near the thermostat housing: One hose (usually the hot one) will often connect near the thermostat housing, as it receives hot coolant from the engine.
* Near the firewall: The hoses will run along or near the firewall to connect to the heater core inside the vehicle's passenger compartment. You'll likely need to look carefully along the firewall, potentially near the intake manifold area.
* Upper and lower connections: There will be at least two hoses – an upper (supply) hose and a lower (return) hose – that connect to the heater core. These will be clamped to the heater core itself.
To locate them more easily:
1. Consult a repair manual: A repair manual specific to your 1997 Chevy Venture will have diagrams showing the exact location and routing of the heater hoses. This is the most reliable method.
2. Use an online repair database: Sites like ChiltonDIY or Alldata offer diagrams and repair information for a fee.
3. Visual Inspection (with caution): Once you've identified the general area, carefully inspect the hoses in the engine bay. They are usually thicker rubber hoses than other hoses in the engine compartment. *Be aware of hot surfaces and moving parts!* Wait for the engine to cool completely before working near it.
Remember safety first. If you are not comfortable working on your vehicle, it's best to take it to a qualified mechanic.
