The Magnum GURU Plug is a higher discharge capacity version of the standard GURU Plug. The Magnum GURU Plug is a self-operating thermostatic drain valve that responds to engine coolant temperature and will pop open and drain when coolant reaches the setpoint (35°F or 40°F). This provides almost a full 1.2in bore to rapidly drain a locomotive before freeze damage can occur.
Resetting and rearming the Magnum GURU Plug is easily accomplished by simply reheating the cartridge and utilising the slotted actuator feature with the GURU Flag and Clip tool. This feature prevents the GURU Plug from triggering open again while refilling the cooling system with cold water.
