Keep part number on hand for scheduled maintenance or emergency cooling system repairs to get your generator back online fast.
Key Features
- OEM-Grade Hose Construction — Manufactured to Wacker Neuson's original material and pressure specifications, ensuring the hose withstands the thermal cycling and coolant flow demands of generator operation.
- Drop-In Fitment for G130 and G150 Series — Connects directly to the factory lower radiator ports with no trimming or adapter fittings required, covering Standard, Cold Weather, and Custom T4i variants.
- Broad Model Coverage — A single part number covers the full G130 and G150 generator families, including mobile generator configurations, simplifying parts inventory for fleet operators.
- Protects Engine Operating Temperature — A healthy lower radiator hose keeps coolant flowing freely between the radiator and the engine block; a cracked or collapsed hose causes overheating and can trigger engine shutdowns under load.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100032427 carries the confidence of OEM traceability and is the same component used in original production builds.
The lower radiator hose carries coolant from the bottom of the radiator back to the engine's water pump, completing the cooling circuit that keeps the engine running at a safe operating temperature. Unlike the upper hose, the lower hose operates under suction from the water pump, which means a weakened or deteriorating hose can collapse internally and restrict coolant flow even if it shows no outward signs of cracking. Regular inspection and timely replacement of the lower radiator hose is essential to preventing overheating, coolant loss, and unplanned generator downtime on the job.
