To be certain, you should:
* Consult your owner's manual: This is the best resource for the precise location for your specific truck's year and model.
* Use a repair manual: A Haynes or Chilton manual for your specific year and model will have diagrams showing the EGR valve's location.
* Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to enter your vehicle's information and view a diagram of the engine, showing the EGR valve.
Don't solely rely on general descriptions. Precise location can change slightly between model years. Referencing your vehicle's specific documentation is crucial for accurate identification.
