Where is the egr valve on a 4.0 liter ranger?

The EGR valve location on a 4.0L Ford Ranger varies slightly depending on the year and specific engine configuration, but it's generally found on the passenger side (right side) of the engine, near the intake manifold. It's often a relatively small, rectangular or cylindrical component with a vacuum line connected to it.

To be absolutely certain, you should:

* Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams and specific instructions.

* Use an online parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model, and then view a parts diagram showing the location of the EGR valve.

Searching online for "4.0L Ford Ranger EGR valve location [Year of your Ranger]" will also likely yield helpful images and forum discussions. Remember to always double-check the year of your truck for accuracy.
