The Multiquip EE49009 Radiator/Upgraded CAC Cummins QSB5-G3 is a genuine OEM assembly designed for QSB5-G3 series equipment. This combined cooling assembly delivers precise thermal management across both the engine coolant circuit and the charge air system, ensuring your machine operates within its engineered temperature range. Sourced directly from Multiquip, this upgraded CAC version replaces the original charge air cooler with an enhanced unit, making it the correct service replacement for QSB5-G3 powered applications.
Key Features
- Upgraded Charge Air Cooler Core — Features an improved CAC core specification over the original, delivering better charge air temperature reduction and supporting engine efficiency under sustained load.
- Genuine OEM Assembly — Manufactured to Multiquip's exact engineering tolerances for coolant flow capacity, tank wall thickness, and core fin density — critical for a combined radiator/CAC unit where both circuits must perform simultaneously.
- Direct-Fit for QSB5-G3 Applications — Engineered to match the OEM mounting configuration, hose port placement, and bracket interface of the QSB5-G3 powered equipment, allowing straightforward installation without adapters.
- Dual-Circuit Cooling Performance — Handles both engine coolant and compressed charge air in a single assembly, reducing the number of potential leak points compared to separate component installations.
- Prevents Heat-Related Engine Stress — A degraded or leaking radiator or CAC causes coolant loss, elevated intake temperatures, and reduced power output. This replacement restores the full thermal protection the engine requires.
The radiator in this assembly circulates coolant through the engine block to absorb combustion heat, then dissipates that heat through the core before returning cooled fluid back into the system. The charge air cooler (CAC) works alongside it by cooling the compressed air leaving the turbocharger before it enters the engine's intake manifold — denser, cooler air means more efficient combustion and better power output. When either component fails, engine temperatures rise quickly, power output drops, and sustained operation risks serious internal engine damage. Replacing a worn or damaged unit with the part restores proper thermal management and protects the engine investment in your QSB5-G3 powered equipment.
