The Coolant Level Gauge Tube Assembly consists of a tube and level float, and this assembly is connected between the lower and upper valves of the expansion tank. As the coolant level fluctuates, the Red Line tube is integrated into the assembly as a visual indicator. As the coolant level fluctuates, the level float moves up or down, transmitting this information through the tube. The Red Line tube provides a clear visual reference, allowing for easy monitoring of the coolant level.Attributes:• Provided with Redline tube and low-thermal-expansion with excellent heat resistance, resistance to thermal shock, chemical resistance• Manufactured to precise specifications and are built for durability and reliabilityApplications:The Coolant Level Gauge Tube Assembly monitors and controls the coolant level in the expansion tank. The assembly enables accurate measurement of the coolant level through the movement of the level float. This allows operators to maintain optimal coolant levels, ensuring efficient cooling and preventing engine overheating.
