Where is the PCV valve on a 2002 Pontiac Bonneville?

The PCV valve on a 2002 Pontiac Bonneville is located on the valve cover. More specifically, it's usually on the passenger side (right side) valve cover. However, the exact placement can vary slightly depending on the engine (3.8L or 3.4L). It's a small, usually black, plastic or metal valve with a hose connected to it.

To be absolutely certain, you should:

* Consult your owner's manual: This is the best resource for the precise location on your specific vehicle.

* Use a repair manual (like a Haynes or Chilton's): These manuals have diagrams showing the location of the PCV valve and other engine components.

* Search online for a diagram of your specific engine: Search for "[Your Engine Size] Pontiac Bonneville PCV Valve location" (e.g., "3.8L Pontiac Bonneville PCV Valve location") to find images.

Remember to always be cautious when working on your engine and disconnect the negative battery terminal before starting any repair work.
