2011 gmc denali

  1. New to Diesel

    Hey guys my name is Josh and I am new to Diesel's. I have just bought a 2011 GMC 2500HD Denali 6.6L. I got a couple things going on with the truck that I am trying to figure out. I know a lot about gas engines but not much about diesels. Does anyone have a book or a web page that I should visit...
  2. No oil pressure @ 1k rpm

    07.5-10 LMM Duramax Powertrain
    Oil and filter was changed 6k miles ago, Rotella Syn, purolator pure one filter, 16,000 miles on truck total, fixing to change the oil and filter now, will that fix it?
