To be certain, you should:
* Consult your vehicle's repair manual: This is the most accurate source of information for your specific truck.
* Use a diagram: Online parts stores (like AutoZone, Advance Auto Parts, etc.) often have diagrams showing the location of parts for your specific year, make, and model. Search for your truck's details and look for a diagram of the engine.
Because it's under the hood and potentially near hot engine components, always let the engine cool completely before attempting to locate or service this part.
