The Bomag 05903302 Radiator is a genuine OEM cooling component designed for Bomag BW 154 AD-4, BW 151 AD-4, BW 151 AC-4, and BW 141 AD-4 series tandem rollers, including AM variants. Sourced directly from Bomag, this radiator matches the original unit in every critical dimension, connection point, and cooling capacity — so installation is straightforward and the engine runs at the correct operating temperature from the first use. It fits the full range of BW 141, BW 151, and BW 154 tandem rollers covered in this listing, giving fleet operators and service technicians a single verified part number 05903302 for this entire machine family.
Key Features
- Genuine OEM Cooling Performance — manufactured to Bomag's original specifications for core density, tank capacity, and pressure rating, ensuring the engine maintains proper thermal regulation under continuous compaction loads.
- Direct-Fit Replacement — matches the original mounting brackets, hose connections, and inlet/outlet ports on compatible tandem rollers, allowing a clean swap without modification to fittings or bracketry.
- Broad Tandem Roller Coverage — fits BW 141 AD-4, BW 141 AD-4 AM, BW 151 AD-4, BW 151 AD-4 AM, BW 151 AC-4, BW 151 AC-4 AM, BW 154 AD-4, and BW 154 AD-4 AM tandem rollers.
- Engine Protection Under Load — a correctly functioning radiator keeps coolant temperatures in range during high-duty asphalt compaction cycles, preventing heat-related engine stress and the loss of compaction output that follows overheating.
- Verified Part Number Integrity — ordering by part number 05903302 ensures you receive the exact assembly engineered for these machines, eliminating the risk of fitment errors that can lead to coolant leaks or improper engine cooling.
The radiator is the primary heat-exchange component in the engine cooling system. Hot coolant circulates from the engine into the radiator core, where airflow drawn through by the cooling fan dissipates the heat before the cooled fluid returns to the engine. On tandem rollers operating in warm conditions or at sustained high loads, the radiator works continuously to keep engine temperatures within the safe operating band. When a radiator becomes internally blocked, corroded, or physically damaged, coolant temperatures climb, triggering overheating shutdowns and risking serious engine damage if the machine continues to operate.
