The Wacker Neuson Upper Radiator Hose is a genuine OEM component designed for G100 and G120 series portable generators. This hose is confirmed to fit multiple T4i configurations across both generator families, including Custom, Standard, Cold Weather, and Hertz variants. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a proper seal and correct routing within the cooling circuit. Keep your generator running at the right operating temperature with the confidence of an exact-match part.
Key Features
- OEM-Grade Hose Construction — Manufactured to original material and wall-thickness specifications, ensuring the correct pressure rating and flexibility for the G100 and G120 cooling system.
- Direct-Connect Fitment — Molded to match the original hose routing and connection points, seating correctly against the radiator and engine coolant ports without modification.
- Broad G-Series Compatibility — Fits G100 and G120 T4i generators across Custom, Standard, Cold Weather, and Hertz configurations, covering a wide range of units within these two generator families.
- Cooling System Integrity — A properly seated upper radiator hose maintains consistent coolant flow between the engine and radiator, preventing overheating and protecting the engine under continuous load.
- Fuel System Safety Compliance — Coolant leaks caused by a cracked or collapsed hose can create hazardous conditions near hot engine components; replacing a worn hose promptly maintains safe operation of your generator.
The upper radiator hose carries coolant from the engine's thermostat housing to the top of the radiator, where heat is dissipated before the coolant cycles back through the engine. It is a critical link in the closed-loop cooling circuit of liquid-cooled generators like the G100 and G120 — if the hose cracks, collapses, or loses its seal at either connection point, coolant is lost and the engine can overheat rapidly. A worn upper radiator hose is one of the most common causes of unexpected generator shutdowns on the job, making timely replacement essential to maintaining output availability.
