i know there is problem with the 2.7l ones and mine is leaking and its very annoying. it looks easy to fix my self but some ppl say you gotta take a nut off in the back on the engine to let the metal cooling pipe move freely a bit. but no one shows where that nut is. do i need to take off my intake and TB to get to it other wise i cant see what nut they speak of . any one got pics or a nice detailed way of getting to it.
