Key Features
- Genuine OEM Cooling Assembly — Manufactured to the original design specification, ensuring correct coolant flow capacity and charge air cooling efficiency for the Cummins QSB5-G3 engine.
- Direct-Fit Replacement — Engineered as a complete Radiator/CAC Assembly to align with existing mounting points and hose connections on QSB5-G3 equipped machines without alteration.
- QSB5-G3 Fitment — Confirmed compatibility with Cummins QSB5-G3 powered Multiquip equipment; use model code QSB5-G3 to verify your application before ordering.
- Maintains Engine Operating Temperature — A properly functioning radiator keeps coolant temperatures in the safe operating range, protecting the engine from heat-related damage during sustained heavy-duty use.
- Charge Air Cooling Efficiency — The integrated CAC (Charge Air Cooler) section reduces intake air temperature after turbocharging, supporting consistent engine output and fuel efficiency.
The radiator in this assembly circulates coolant through the engine block to absorb heat generated during combustion, then dissipates that heat through the core before returning cooled fluid back to the engine. The Charge Air Cooler (CAC) works alongside the radiator to cool compressed air delivered by the turbocharger before it enters the intake manifold — denser, cooler air improves combustion efficiency and helps the Cummins QSB5-G3 maintain rated power output. When either component fails or becomes restricted, the engine is at risk of overheating, power loss, and accelerated internal wear, making timely replacement of the EE49021 assembly critical to keeping your equipment running reliably.
