The EVAP Canister Purge Solenoid is located under hood, top, front of the engine. No special tools are required, and the procedure is as follows:

 

 

 

  1. Remove the engine sight shield.

If the connector (1) is attached to the soleniod, I don't get why we move over to a bolt (2) that is not associated with the soleniod. And (3) doesn't seem to have anything to do with the solenoid.

I apologize if I am being dense.

Expert:  Ron Z. replied 3 years ago.

The "connector" is an electrical connector. It must be unplugged before you can remove the sensor.

 

Customer: replied 3 years ago.

I understand that. Please reference the diagram you sent? It does not seem that #s (2) and (3) have anything to do with the solenoid.

Isn't the soleniod the 3 or 4 inch high black thing under the connector?

Expert:  Ron Z. replied 3 years ago.

Ahhh.. ok... i see what you're saying. The (2) and (3) are related to the 3rd image.The (2) and (3) on the 2nd image are wire harness hold-down clip, and Alternator electrical connector, repsectively (just shown for "location" purposes). I see now the confusion. Sorry about that. I should have edited out the (2) and (3) from the 2nd image.

 

This is how it should be:

  • Remove the EVAP canister purge solenoid bolt (2).

  • Remove the EVAP canister purge solenoid (3) and insulator (1).

    Hope that makes it clearer! Sorry!

    ok, thanks. I was pretty sure that was the case. But once I tried to change $10 fuel filter on an Explorer, screwed-up the metal fuel lines and ended up spending $1200. So I just wanted to be sure.
    Expert:  Ron Z. replied 3 years ago.

    Ahhh. I didn't even realize what I had done there. My fault. Hope I cleared it up enough.

     

    As for the Ford fuel filter- you should have came here first, and I could have shown you the special tool needed to remove the filter, how to use it, and where to get it for cheap money!!
