The Bomag 05903138 Radiator is a genuine OEM component designed for MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers. Sourced directly from Bomag, this radiator is manufactured to the same specifications as the original unit it replaces, ensuring a correct, hassle-free installation. It is the recommended replacement for any MPH-series recycler/stabilizer showing signs of coolant loss, overheating, or cooling system failure.
Key Features
- Genuine OEM Cooling Integrity — Built to Bomag's original thermal and pressure specifications, this radiator delivers the same core density, tank construction, and coolant capacity as the factory unit — critical for sustained engine temperatures under heavy stabilizing loads.
- Direct-Fit Replacement — Engineered to match the original mounting points, inlet/outlet ports, and hose connections on compatible MPH recycler/stabilizers, so installation follows the standard service procedure without modification.
- Confirmed Fitment — Compatible with the MPH 121, MPH 122, and MPH 122-2 recyclers/stabilizers. Reference part number 05903138 to confirm the correct application before ordering.
- Overheating Prevention — A properly functioning radiator keeps the engine operating within its designed temperature range during continuous mixing and stabilizing passes. A compromised radiator risks thermal shutdown and accelerated engine wear.
The radiator is the primary heat exchanger in the engine cooling system. It transfers heat from the circulating coolant — which absorbs thermal energy from the engine — out into the ambient air, keeping the engine within a safe operating temperature range. On heavy-duty recyclers/stabilizers like the MPH 121, MPH 122, and MPH 122-2, the engine works under sustained, high-load conditions during soil mixing and stabilization passes, placing constant demand on the cooling system. When a radiator develops internal blockages, external damage, or leaks, coolant flow is restricted and the engine is exposed to damaging heat levels that can lead to head gasket failure, warped components, or complete engine seizure.
