    my company runs APU's, and i just got into a new truck that has a blackrock on it, and it only for about 30 mins then shuts off, the box inside shows the coolant light lit up, but its got plenty of coolant in it.
    anyone els run these extreamly loud APUs? and have maybe the same problem?

    Possibly a faulty coolant sensor sending unit.
