autumnwalker Posted October 7, 2014 Report Share Posted October 7, 2014 The H2 dropped a coil last week and I'm wondering if I should replace all eight or just the one? It says it was coil pack D - any idea which coils are which on a 6.0L Vortec GM? Link to comment Share on other sites More sharing options...

TRUXterra Posted October 7, 2014 Report Share Posted October 7, 2014 Find out your firing order, google does wonders ^^ This, and replace that one only. I replaced one on my X 4 years ago (cracked boot) and the other 5 are still working fine to this day. FWIW, I just rolled past 174k kms on the way home today.
