Multiquip EEN0020100 GBX III Overflow Radiator Tank - OEM Replacement Part

The overflow radiator tank maintains proper coolant system pressure and provides thermal expansion capacity for engine-driven Globug light towers operating in demanding job site conditions. This pressurized reservoir allows coolant to expand during heating cycles and return to the radiator during cooling, preventing air pockets and maintaining optimal engine temperature regulation. Critical for mobile lighting units that experience frequent transport, variable load conditions, and extended runtime periods.

This GBX III-specific overflow tank is engineered to handle the thermal cycling demands of trailer-mounted light tower systems where consistent cooling performance directly impacts uptime. Failure symptoms include coolant loss, overheating during operation, steam from the engine compartment, or visible cracks in the tank body. Regular inspection of the overflow tank, connecting hoses, and pressure cap should be part of your preventive maintenance routine to avoid costly engine damage from cooling system failure.

Compatible with the following Multiquip Globug light tower models:

• GBX12SK
• GBX24BK
