Overview

Upgrade your Mercedes cooling system with the YzusGomumu Engine Radiator Coolant Overflow Reservoir, a sensor-equipped replacement designed for select GL and ML models from 2006 to 2015. This reservoir helps manage excess coolant as the engine warms and cools, contributing to a more stable cooling loop and a cleaner coolant circuit.

Equipped with a cap and a smart monitoring sensor, the unit can track coolant level and temperature in real time. When readings indicate low coolant or rising temperature, the system can trigger alerts to support timely maintenance actions, potentially reducing the risk of overheating or related issues. The design emphasizes a secure seal and minimal risk of leaks, even in a demanding engine bay environment.

Smart monitoring at a glance

  • Real-time coolant level sensing to help you stay informed about your cooling system
  • Temperature monitoring to spot unusual heat while driving or idling
  • Alerts to prompt quick checks and preventive action

Quality, durability, and fit

  • Premium materials chosen to withstand engine bay conditions and resist corrosion
  • Cap included for secure sealing and spill prevention
  • Rugged construction designed for long-term reliability in daily driving
