The clip at the end of the cable is inserted into the slot in the GURU® stem/cam after warming the nose of the cartridge. The flag can then be attached to the side of the locomotive by its magnetic base to provide an external indication that the GURU® has been disabled. When the locomotive’s cooling system is back up to temperature, the clip is easily removed and the GURU® is again armed to protect the locomotive.


The GURU® Flag and Clip Tool allows filling a locomotive cooling system with cold water that would otherwise trip the GURU® Plug open. When used on a deactivated GURU® Plug, this tool serves as a highly visible indicator that the plug has been disabled. The GURU® Flag will help prevent leaving a penny or washer in the valve stem, defeating the valve’s function and possibly resulting in freeze damage to the locomotive.
