The Wacker Neuson Overflow Hose Ml is a genuine OEM component designed for the G50, G70, G100, G120, G130, and G150 series portable generators. Sourced directly from Wacker Neuson, this part matches the original specification exactly — ensuring correct routing, connection sizing, and material compatibility straight out of the box. It fits an extensive range of G-series configurations including Standard, Cold Weather, Custom, Extended Run, URI HVAC, URI CW, Hertz, and 600V Mobile variants across Tier 4 Final and T4i emission levels. When it's time to restore your generator's coolant overflow system, part number is the correct OEM solution.
Key Features
- OEM Material and Dimensional Integrity — Manufactured to Wacker Neuson's original hose specification, including wall thickness, flexibility rating, and end-fitting compatibility for the G-series cooling system.
- Drop-In Connection Fit — Connects directly to the overflow reservoir and coolant system ports on compatible G-series generators without rework or adapter fittings.
- Broad G-Series Coverage — Fits G50, G70, G100, G120, G130, and G150 generator models across Standard, Cold Weather, Custom, Extended Run, URI HVAC, URI CW, Hertz, and 600V Mobile configurations in T4F and T4i variants.
- Protects the Cooling Circuit — A properly functioning overflow hose safely routes excess coolant away from the engine bay; a cracked or collapsed hose can cause coolant loss, overheating, and unplanned shutdowns on the jobsite.
- Genuine OEM Part — Carries the Wacker Neuson part number 5200012542, giving you confidence in traceability and correct application every time.
The overflow hose in a liquid-cooled generator directs excess coolant from the radiator's expansion tank to a recovery reservoir as the engine heats up, then allows it to return as the system cools down. This controlled flow prevents coolant from being lost to the ground while maintaining the correct fluid level in the cooling circuit. When the overflow hose cracks, kinks, or softens with age, the system loses its ability to manage thermal expansion properly — leading to coolant loss, rising engine temperatures, and potential overheating damage during extended generator operation.
