Replacement of EGR valve on a 4.7 liter

I needed to replace me EGR valve for some time now. My check engine light has been on and off for a while. I had the code checked and as I assumed it was the EGR valve.

Replacement of the EGR valve while not complicated (four bolts 2 8mm, and 2 13mm) can be a bit of a challenge due to its location. ITs tucked up next to the firewall on the driver side of the 4.7 liter engine. I struggled to find the right (short) extension to remove the hose from the EGR valve. After a lot of trial and error (mostly error) I hit on the right combination and the hose was removed. The valve is held in by two bolts which can be a bit of a pain to get to, but with a little persuasion came off without an issue. The wire connection was removed and the tired valve was extracted.

Installation was difficult as its hard to align the bolts with the holes. This is where I struggled. The gasket is threaded which does help to get everything in place, but the area is tight. After some perseverance, I managed to successfully mount the EGR valve and reattach the hose.

In all it took about 2 hours. If I had to to it again, I could probably do it in under an hour.

Again its not difficult to replace, but its accessibility is limited. You will need to be a little creative with socket extensions. With some perseverance it is a job us backyard mechanics can handle.
