Hello - attempted to change the EGR valve in my 2005 Pacifica with 3.5L. I got both of the lower EGR Tube bolts out (where they attach to the EGR valve itself) and dropped one, which must have gone into some black hole because I can't find it anywhere. Does anyone know the size of this bolt, other than that it has an 8mm head?

I also couldn't get to the 10mm bolts on the EGR valve itself, even though it looks deceptively accessible. I'll have to look for some additional tools for that. So for now I have a failed job, and am now missing one of the two bolts in the tube.

Any suggestions? Thanks in advance!

 

Since you have one bolt, try it in the other hole and see if it fits. If so, get another one like it. If too small or too big, buy accordingly.

 

I thought of that, didn't want to have it fall into the black hole while removing it, so I thought I'd ask if anyone knew the specs.
