    Plug in a scan tool. It will cycle the fans. Quick and easy way to see if the fans/IRCM is functional.

    The upper hose always gets rock hard at operating temperature. Perfectly normal and has nothing to do with air.

    Took it for another 10 mile drive never got above 186 and the fans are stock and I know now that they are functional. Seems as though air in the system and a bad ircm was my problem but the only way I am going to know is by driving it lol.
