    Can't seem to figure out what is keeping the cooling fan engaged.
    changed temp sensor, has a new clutch that we can make work
    by feeding a hot wire to the fan air selinoid on the fire wall. The
    dealer said the ECM is good. Any advice or fuse/wiring diagram would be
    appreciated

    There is small valve on firewall, under foot brake valve, hiddent in wires and air lines. sometimes this valve fail.

    really I have version-2 diagram, but volvo includes engine interface wiring only (from MCFC cab chassis connector). wiring diagram of engine actuators is available on Cummins portal, so use and CM870 wiring diagram
