The Wacker Neuson G120 CAC Radiator is a genuine OEM component designed for the G120 portable generator series, including the Mobile Generator (Cold Weather), Skid-Mounted Mobile Generator, and Mobile Generator (Custom) configurations. As a direct-from-manufacturer part, the is built to the exact dimensional and thermal specifications of the original unit it replaces. Sourcing a genuine OEM radiator assembly ensures the cooling and charge-air system performs exactly as Wacker Neuson engineered it, maintaining proper operating temperatures and engine output across all G120 generator variants.
Key Features
- Genuine OEM Thermal Specification: — Manufactured to the exact core density and coolant-flow rating of the original G120 assembly, ensuring the cooling system maintains correct engine operating temperature under load.
- Integrated CAC Design: — Combines the radiator and charge-air cooler in a single bolt-in assembly, matching the original mounting points and coolant/air connections on the G120 generator frame.
- Confirmed G120 Fitment: — Verified for G120 Mobile Generator (Cold Weather), Skid-Mounted Mobile Generator, and Mobile Generator (Custom) configurations.
- Protects Engine Performance: — A functioning radiator and charge-air cooler keep coolant temperatures and intake charge temperatures within spec; a degraded unit can lead to overheating, derating, and unplanned shutdowns during critical power generation operations.
- Fuel System and Emissions Compliance: — Correct charge-air cooling directly supports proper air-fuel mixture and emissions performance; using a correctly rated CAC radiator assembly keeps the G120 operating within its designed parameters.
The radiator manages engine coolant temperature by transferring heat away from the coolant as it circulates through the core, preventing the G120 generator's engine from overheating during extended run cycles. The charge-air cooler (CAC) portion cools the compressed intake air delivered by the turbocharger before it enters the engine, increasing air density to support efficient combustion and rated power output. When either section of this combined assembly fails — through core damage, internal blockage, or leakage — the engine will overheat or lose output capacity, making prompt replacement with a correctly specified unit essential to keeping the generator online.
