2006 Chevy Silverado 4.3L V6: On the Silverado, the PCV valve is typically located on the valve cover, often near the rear or side. It's usually a small, usually black, plastic or metal valve with a hose attached. You'll need to consult a repair manual specific to your year and engine to pinpoint its exact location, as there can be slight variations.
2006 Chevy Equinox: The Equinox's PCV valve location will also be on the valve cover, but again its precise spot might differ slightly from the Silverado. Checking a repair manual specific to the Equinox's 4.3L V6 (if equipped) is essential. If your Equinox has a different engine size, the location will be completely different.
How to find it:
1. Consult a Repair Manual: This is the most reliable method. A Haynes or Chilton manual, or an online service like AllDataDIY, will provide diagrams and precise locations.
2. Visual Inspection: Once you have located the valve covers (there will be two on a V6), carefully examine them for a small valve with a hose attached. The hose usually runs to the intake manifold.
3. Online Forums: Search online forums specific to your vehicle year and engine. Someone may have already posted pictures or descriptions of their PCV valve location.
Important Note: Always remember to disconnect the negative battery terminal before working on any engine components. Also, be careful not to damage any hoses or other parts during your search.
