The Multiquip EE50719 Radiator Aftercooler Rocor is a genuine OEM cooling assembly designed for the KTA50-G9 generator. This is a direct OEM replacement sourced through Multiquip's authorized parts network, giving you confidence that the unit meets the original design specifications for the KTA50-G9 platform. If your generator is running hot, losing charge air efficiency, or showing signs of cooling system degradation, the part is the correct factory replacement to restore proper thermal management. DHS Equipment stocks this part to keep your KTA50-G9 back in service with the right component the first time.
Key Features
- Genuine OEM Cooling Performance — Engineered to the original thermal transfer and pressure specifications required by the KTA50-G9 engine system, not a generic approximation.
- Integrated Radiator and Aftercooler Assembly — Combines the engine coolant radiator and charge air aftercooler (Rocor) in a single matched unit, simplifying service and ensuring both circuits are renewed together.
- Direct Application for KTA50-G9 — Confirmed fitment for the Multiquip KTA50-G9 generator; mounts and connects using the existing hardware and plumbing without improvised adaptation.
- Restored Charge Air Density — A functioning aftercooler keeps intake air temperatures in check, maintaining combustion efficiency and protecting engine output under load.
- Coolant Circuit Integrity — Replacing a degraded radiator core eliminates the risk of overheating-related engine damage, which is particularly critical in continuous-duty generator applications.
The radiator in this assembly manages engine coolant temperature by transferring heat from the circulating coolant to the ambient air — if it becomes blocked, corroded, or develops a leak, the engine will overheat and shut down under load. The aftercooler (also called a charge air cooler or Rocor unit) works alongside the turbocharger by cooling compressed intake air before it enters the engine, which increases air density and allows the engine to produce its rated power output cleanly. When either component fails, the KTA50-G9 will experience thermal runaway, reduced power, or automatic protective shutdown — making timely replacement of the Multiquip EE50719 essential to keeping a generator of this class running reliably.
