Thanks for the link. I'm a noob so i didn't use the search. As an FYI to any one doing this repair, got my parts from pelicanparts.com and the coolant pipe upgrade kit from Sonnen Porsche. they have an OEM parts link that was great and the price was $445 with shipping. Don't forget to order intake gaskets, the Kluber lube, coolant, thermostat and O ring, I'm also replacing my upper and lower radiator hoses as part of the Cayenne's regular maintenance. Gonna dive in this weekend or next.
Thank you to this forum and all the input from everyone. Will let you know how i come out on the
