Wacker Neuson 5200004107 Radiator CAC Assembly G70 T4i

The Wacker Neuson Radiator CAC Assembly G70 T4i is a genuine OEM cooling assembly designed for the G70 generator series. This assembly serves the G70 Custom T4i, Standard T4i, Cold Weather T4i, Extended Run T4i, Hertz T4i, and URI HVAC configurations — covering the full G70 Tier 4i product range. As a factory-sourced component, it is built to the exact design tolerances required by the G70's engine cooling and charge-air cooling system. Keep a verified OEM part number on hand to avoid cooling system mismatches on this generator platform.

Key Features

• OEM Cooling Integrity — Genuine Wacker Neuson construction ensures correct core density, tube count, and fin spacing matched to the G70 T4i engine's thermal load — not a generic approximation.
• Integrated Radiator and Charge-Air Cooler — Combined radiator and CAC assembly installs as a single unit, maintaining proper plumbing alignment and airflow routing within the G70 enclosure.
• Full G70 T4i Model Coverage — Confirmed fitment across Custom, Standard, Cold Weather, Extended Run, Hertz, and URI HVAC G70 T4i variants under part number 5200004107.
• Engine Temperature Management — A correctly functioning assembly keeps coolant and charge-air temperatures within operating range, protecting the Tier 4i engine from heat-related power loss or shutdown under load.
• Emissions System Compatibility — The Tier 4i charge-air cooler section is sized specifically for the G70's aftertreatment-equipped engine; substituting a non-spec core can affect combustion efficiency and emissions compliance.

The radiator in this assembly circulates engine coolant through a finned core, dissipating heat into the airflow drawn through the generator enclosure. The charge-air cooler (CAC) works alongside it, cooling the compressed intake air delivered by the turbocharger before it enters the engine — denser, cooler air improves combustion efficiency and keeps the Tier 4i emissions system operating within spec. When either section degrades through core damage, internal scaling, or external fin blockage, the engine is exposed to elevated operating temperatures that can trigger thermal protection shutdowns or accelerate wear on internal components.
