* Your Owner's Manual: Check your owner's manual. While it may not have a detailed diagram, it might show the major components and their general vacuum connections.
* Repair Manual: A Haynes or Chilton repair manual specifically for your year and engine should have a detailed vacuum line diagram. These are readily available online and at auto parts stores. This is your best bet for a comprehensive and accurate diagram.
* Online Forums and Communities: Websites and forums dedicated to Chevy S-10s (like S10Forum.com or similar) are excellent resources. Search for your specific year and engine, and you may find someone who has posted a diagram or can provide guidance. Be wary of the accuracy of user-submitted information, though. Always cross-reference.
* Automotive Parts Websites: Sites like AutoZone, Advance Auto Parts, or Napa Auto Parts often have online parts catalogs. While they may not offer a vacuum diagram directly, you can look up parts related to vacuum (like the brake booster, PCV valve, etc.) and the accompanying diagrams might show their connections. This is less reliable for a complete picture but may help with specific parts.
Important Considerations:
* Accuracy: Always verify any diagram you find against your actual vehicle. Variations can exist.
* Color-Coding: Pay close attention to the color-coding of the vacuum lines on your engine. This is crucial for accurate reconnection.
* Safety: If you're not comfortable working with vacuum lines, consult a qualified mechanic. Incorrect vacuum connections can lead to poor engine performance or even damage.
Remember to specify the exact year, model, and engine code (if you can find it) when searching online to get the most accurate results. The repair manual is your most reliable source.
