I replaced one of mine. Don't remember the part # but according to the service man it was the updated one that GM just put out to cure the problem. We'll just wait I see if he was telling the truth.

Were these "updated" lines available in late Jan.? That is when I got mine done. Hope when the cold comes back, I don't have the same problem.

Every LBZ has the possibility of leaking. They leak mainly or only in the winter months when its cold. the lines shrink or something due to the cold. i got mine replaced right after they stoppe leaking by themselves when it got warm again. My bros, my dads, my buddies, and my other buddies 07 classics all leaked untill it got warm again. The "updated" lines are i belive no different and still leak from what i remember hearing. we will see come cold.

Bump to the top. Got my 1st leaker at 81k+ miles on the pressure line to the bottom of the radiator. Was running high idle to warm up a few times recently at below or near zero. IIRC the Canadian guys got a letter last winter telling them to disable high idle because of it. My bad I guess.

Mine are still leaking. I had a appointment for the dealer to fix them, But I still haven't got it down there yet.
