Key Features

• Genuine OEM Cooling System Integrity — The Rocor radiator component meets the exact thermal management specifications required by the Cummins QST30 engine, maintaining proper coolant flow and heat rejection under load.
• Complete Assembly Configuration — Supplied as a full assembly, this unit consolidates the engine-side and radiator-side components into a single matched unit, simplifying the replacement process.
• Confirmed QST30 Fitment — Engineered specifically for QST30 series equipment; verify your model and serial plate before ordering to confirm compatibility.
• Sustained Engine Protection — A properly functioning radiator assembly keeps the QST30 engine operating within its designed temperature range, preventing overheating events that can cause irreversible engine damage.
• Marine-Grade Radiator Construction — The Rocor marine radiator specification is built to withstand the corrosive and humidity-intensive demands of marine operating environments, extending service life in harsh conditions.

The Cummins QST30 Assembly with Rocor Radiator Marine serves as the central cooling solution for the QST30 engine, circulating coolant through the radiator to dissipate heat generated during operation and regulate engine temperature. The Rocor marine radiator is specifically engineered for environments where standard radiator materials would be vulnerable to accelerated corrosion, making it essential for marine-duty applications. When this assembly degrades or fails, the engine becomes susceptible to thermal overload, which can lead to costly internal damage and unplanned downtime.
