The Wacker Neuson Fan 25.5 G160 is a genuine OEM cooling fan designed for G120 and G160 series mobile and skid-mounted generators. As a factory-sourced component, this fan is built to the exact dimensional and performance specifications required by both the G120 and G160 generator families, covering standard, cold weather, and custom configurations. Wacker Neuson genuine OEM parts carry the same quality assurance as the original components installed at the factory. Confirm your generator's model number against the fitment list before ordering to ensure you have the correct fan for your unit.
Key Features
- Genuine OEM Cooling Performance — Factory-sourced fan engineered to move the precise airflow volume required by the G160 and G120 generator engines, maintaining correct operating temperatures under load.
- Exact Dimensional Match — The 25.5 fan diameter matches the original blade geometry and hub mounting pattern, allowing a straightforward drop-in installation without modification to the fan shroud or drive assembly.
- Broad G-Series Fitment — Compatible across multiple G120 and G160 configurations, including skid-mounted, standard mobile, cold weather, and custom-build variants.
- Protects Engine from Thermal Damage — A worn or cracked cooling fan reduces airflow across the engine, leading to overheating, thermal shutdown, and accelerated wear on internal components. Replacing it promptly keeps the generator running at rated output.
- Electrical Safety Compliance — Correct fan operation is critical in generator applications where engine heat management directly affects alternator performance and safe electrical output. Using an OEM-spec fan helps maintain the integrity of the system.
The cooling fan draws or directs airflow across the engine to dissipate heat generated during power production. In generator applications, maintaining consistent engine temperature is essential — if the fan becomes cracked, imbalanced, or fails entirely, airflow is disrupted and the engine temperature rises rapidly, triggering thermal protection shutdowns or causing lasting damage to internal components. Replacing a failed fan with the correct OEM part restores proper thermal management and allows the generator to sustain its rated electrical output reliably across extended run cycles.
