On a 1992 S10 Blazer, the EGR (Exhaust Gas Recirculation) valve is typically located on the intake manifold, near the back of the engine. It is connected to the exhaust manifold via a metal tube. You may need to remove some components or hoses to access it easily. Always consult a repair manual for your specific engine configuration for precise details.
If you want to locate a new egr valve, check with your local auto parts store. If you want to know where the egr valve is located on your vehicle, post the year and engine size of your S10.
