The Multiquip EE48689 Radiator/CAC Assembly Cummins QSM11 is a genuine OEM cooling assembly designed for QSM11-powered Multiquip equipment. This is a direct OEM replacement sourced through the Multiquip parts program, ensuring the assembly meets the original design specifications for your machine. Confirmed fitment for QSM11 series units makes this the correct choice when a full cooling assembly replacement is required.
Key Features
- Integrated Dual-Function Cooling Assembly — Combines the radiator and charge air cooler (CAC) into a single matched assembly, ensuring both engine coolant and compressed intake air are managed together as originally engineered.
- Genuine OEM Construction — Built to the same internal flow rates, tank dimensions, and core density as the original unit, so the Cummins QSM11 engine operates within its designed thermal range.
- Direct-Mount Replacement — Designed to align with the existing mounting points, hose connections, and charge air plumbing on QSM11-powered equipment, allowing straightforward installation without fabrication.
- Protects Engine Performance Under Load — A functioning radiator/CAC assembly keeps coolant temperatures and intake charge temperatures within spec; a degraded or leaking unit can trigger derates, overheating shutdowns, or accelerated engine wear.
- Confirmed QSM11 Fitment — Verified for Multiquip QSM11 series equipment — use part number EE48689 to confirm compatibility before ordering.
The radiator dissipates heat from engine coolant that circulates through the Cummins QSM11 block, preventing thermal overload during sustained operation. The charge air cooler (CAC) works alongside it, cooling the compressed air from the turbocharger before it enters the engine's intake manifold — denser, cooler air means more efficient combustion and better power output. When either component in this assembly fails through leaks, core damage, or blockage, the engine is at risk of overheating, loss of power, or automatic shutdown, making timely replacement with the correct OEM assembly critical to keeping the machine operational.
