Cold Water Refill Tool Overview
Anti-tamper dome caps prevent access to the GURU® Plug resetting stem, eliminating the practice of using a penny or washer to hold the plug closed. The GURU® Flag and Key provides the dedicated interface needed to temporarily deactivate these configurations during cold-water refill.
It can be used with compatible Magnum and DL2.1 GURU® Plugs.
For GURU® configurations with a slotted stem/cam, use the GURU® Flag and Clip.
Design Features
- Magnetic base attaches to locomotive body or running board
- Optional strobe light for increased visibility
- 3 lanyards for easier maintenance
- Long cable length for easy placement
- Quick release pin inserts into anti-tamper dome cap for temporary deactivation

How to use the GURU® Flag and Key Tool
After the cartridge is warmed, the key is inserted into the anti-tamper cartridge to temporarily deactivate the GURU® Plug. The magnetic flag can then be attached to the side of the locomotive to provide an external indication that the valve has been disabled. Once the locomotive is operating and the cooling system has returned to the required temperature, the key is removed to reactivate the valve.
Important: The GURU® Plug is temporarily deactivated while the tool is installed. Review the installation instructions before use and do not use the accessory unless the locomotive will be operated immediately afterward.
