Key Features
- OEM-Spec Core Construction — Built to the same internal fin density and tube configuration as the original, maintaining the charge air cooling capacity the QSB7-G5 engine depends on.
- Direct-Fit Assembly — Mounts to the existing bracket and inlet/outlet connections on QSB7-G5-equipped machines with no rework to hose routing or mounting hardware.
- Confirmed QSB7-G5 Fitment — Engineered specifically for the Cummins QSB7-G5 engine; cross-compatibility with other engine families is not assumed or implied.
- Protects Engine Output and Longevity — A properly functioning charge air cooler keeps intake air temperatures in the correct range, supporting full rated horsepower and reducing thermal stress on internal engine components.
- Genuine Multiquip OEM Part — Supplied as an authentic OEM component, carrying the same part number (EE54721) used in Multiquip's official parts documentation.
A charge air cooler (CAC) is a heat exchanger positioned between the turbocharger and the engine intake manifold. Its job is to cool the compressed air delivered by the turbo before it enters the combustion chamber — denser, cooler air carries more oxygen, which is critical for efficient combustion and full power output. When the CAC becomes restricted, leaks, or fails, intake air temperatures rise, which causes the engine to lose power, run hotter, and in some cases trigger protective shutdowns. Replacing a degraded CAC assembly with a correctly specified unit like the Multiquip EE54721 restores the engine's ability to breathe efficiently and perform at its rated capacity.
