Easy!MattSWE said:after loosening the two bolts from the back of the intake manifold, how do I possibly get to that threaded nut at the bottom the the egr valve?!? I need to clean it and check the hoses and the modulator filters as well
I just did this 2 weeks ago.
Remove the two bolts that hold the egr, then undo the large nut that holds the egr valve tube at the BOTTOM of the tube NOT the top that connects to the egr valve. There's a bracket that has to be removed to access this nut, but it's easy to remove it, only 2 screws hold the bracket down(I forget which bracket it is, but it's really easy stuff). So you should remove the egr tube with the egr valve as one piece, it's so much easier that way, + you can clean the tube as well this way!
When the egr valve/tube is removed, make sure you clean out the gunk of carbon that's most likely going to be wedged where the egr bolts into the fuel plenium:clap:
good luck and let us know how it worked out for you!
