The Wacker Neuson Radiator CAC Assembly G70-G100 is a genuine OEM cooling assembly designed for the G70 and G100 portable generator series. As a direct factory replacement, this assembly integrates the radiator and charge air cooler (CAC) into a single unit, ensuring correct thermal management and charge air temperature control across all G70 and G100 configurations — including Standard, Cold Weather, Custom, and URI HVAC variants. Wacker Neuson genuine OEM parts are manufactured to the exact tolerances and material specifications used in original production, so installation is straightforward and performance is consistent with the machine as built. Part number fits a broad range of G70 and G100 machine numbers, making it the correct choice whether you're servicing a T4 or T4F-compliant unit.
Key Features
- Integrated Cooling Precision — Combines the engine radiator and charge air cooler into one matched assembly, maintaining the correct coolant flow rates and charge air temperatures the G70 and G100 engines depend on.
- Genuine OEM Construction — Manufactured to original production specifications, with core materials and tank connections that match the factory assembly — no improvised fitment or adapted hardware needed.
- Broad G70 and G100 Coverage — Confirmed fitment across Standard, Cold Weather, Custom, URI HVAC, and Mobile Generator configurations for both the G70 and G100 series.
- Thermal Load Integrity — A fully functional radiator/CAC assembly keeps engine and charge air temperatures within design limits under sustained load, protecting the engine from heat-related power loss and accelerated wear.
- Fuel System and Emissions Compliance — Correct charge air cooling is essential for T4 and T4F Tier 4-compliant engines; a degraded CAC can raise intake air temperatures and compromise combustion efficiency and emissions output.
The radiator in this assembly circulates coolant between the engine and the external air to dissipate combustion heat, keeping the engine operating within its safe temperature range. The charge air cooler (CAC) works in parallel — it cools the compressed air delivered by the turbocharger before it enters the engine's intake, which increases air density, improves combustion efficiency, and protects the engine from heat stress under load. When either component becomes blocked, leaks, or corrodes, the generator can overheat, lose power output, or trigger thermal shutdown. Replacing the assembly as a matched unit with genuine OEM part 5100053807 restores the full cooling capacity the G70 and G100 were engineered to deliver.
