    Viscous fan solus ultra

    Looking for data pids and bi directional controls on a 2008 Chevy trailblazer 4.2 I think software is 17.4.

    You would think by 2008 that something as important as getting good air flow through a radiator that GM would monitor viscous fan clutch fan speed it would show an actual fan rpm and a desired fan rpm and % error that should not be above a certain threshold. Seems like a more important idea to have add 10 years ago than I phone App capability.
    If there is a slight movement felt in the assembly theTurd might ultimately need the waterpump though. I had a 4.2 Envoy that belonged to MrsDiagnosis
