Im not positive, been a while since mine was off, but a 12pt 9/16" cap rings a bell.
If it is stock the manifold should have studs with a 13mm or 1/2 nut holding the valve on.
Yeah I'm pretty sure mine was 13mm or 1/2 nuts on studs.84zz4ss said:
Same here. Two studs that screw in using a "reverse Torx" socket. The tip of the stud is shaped like a Torx driver and takes a socket that fits over it. They don't have to go in super tight. Just snug 'em down and then slide the EGR valve over the studs and install the nuts.
