      You can drain it, but you’ll have it to have nitrogen and a scan tool to fill it properly.

      The diagram just doesn’t show it. Sorry, wrong part number. Parts diagrams can be useless at times. Should be 68302326AA.

      There is a nitrogen tank, on the trucks it’s underneath the bed. I honestly don’t know 100% how the compressor uses the air...

      You can’t get just the filter, have to buy to the intake/suction hose assembly. 68204392AA should be it.

      It is a “sealed” system per se. If the system is empty of nitrogen it won’t just fill it with air. The intake/exhaust for the compressor...

      The inlet/exhaust hoses for the compressor are behind the passenger side tail light/fender. The filter is there as well, if there’s any...

      Problem is you can fix it and a good chance you’ll have problems again next winter.

      That’s like the furthest spot possible from where it actually is lol. On the 1500s the purge valve was by the fuse box for years, until...

      Are any codes set for any misfires? A proper scan tool would allow you to view misfires in real time. Have you done a compression test?
    • Tach_tech
      Do you have access to a scan tool to monitor misfires when it is running? Does it still have the MDS lifters or did you delete them?

      Tach_tech replied to the thread Heater mode actuator.
