You're most likely to find it in one of these general areas:
* Near the Throttle Body: This is a common location. Look closely at the hoses and components near the throttle body; the purge valve is often a small canister-like device with vacuum hoses attached.
* On the Fuel Rail (less common): Sometimes, especially on V8 engines, it might be mounted on or near the fuel rail.
* Under the Intake Manifold: In some configurations, it could be tucked away underneath the intake manifold, making access difficult.
To find it definitively:
1. Consult a Repair Manual: A Chilton's or Haynes repair manual specific to your 1995 Chevy Blazer's engine will show you a diagram and the exact location of the purge valve. This is the best method.
2. Use a Parts Diagram: Use the vehicle identification number (VIN) on a parts website like AutoZone, Advance Auto Parts, or Napa Auto Parts to look up a parts diagram for your specific year, make, model, and engine. This will visually show you where the part is located.
3. Trace the Vacuum Lines: The purge valve has vacuum lines connected to it. Start by identifying the larger vacuum lines near the intake manifold and trace the smaller lines; one of them should lead to the purge valve.
Without knowing the specific engine in your 1995 Chevy Blazer, pinpointing its exact location is impossible. Using a repair manual or parts diagram is strongly recommended.
