The Bomag 05903498 Radiator Cap is a genuine OEM component designed for BC-series refuse and landfill compactors. Sourced directly from Bomag, this radiator cap delivers the exact pressure rating and sealing performance your cooling system requires. It fits the BC 572 RB-2, BC 672 RB-2, BC 672 RB-3, BC 772 RB-2, BC 772 RB-3, BC 772 RS-2, and BC 772 RS-3 refuse and landfill compactors, making it the right choice across a wide spread of the BC heavy compactor lineup. When cooling system integrity matters on demanding landfill operations, specifying the correct OEM part is the straightforward call.
Key Features
- OEM-Correct Pressure Rating — manufactured to Bomag's exact pressure specification, ensuring the cooling system maintains the designed operating pressure and temperature range
- Direct Drop-In Fitment — engineered to the original radiator filler neck dimensions, this cap seats and locks exactly as the factory cap did with no rework
- Broad BC-Series Coverage — fits BC 572 RB-2, BC 672 RB-2, BC 672 RB-3, BC 772 RB-2, BC 772 RB-3, BC 772 RS-2, and BC 772 RS-3 refuse and landfill compactors
- Cooling System Protection — a correctly rated cap holds the system at optimal pressure, allowing coolant to reach its full boiling-point tolerance and protecting against overheating under heavy-duty compaction cycles
- Genuine Bomag OEM Part — supplied as an authentic Bomag part under part number 05903498, verified for this application and backed by OEM sourcing through DHS Equipment
The radiator cap seals the cooling system and regulates internal pressure by opening and closing a spring-loaded valve at a calibrated threshold. By maintaining the correct pressure, it raises the effective boiling point of the coolant, which keeps the engine operating within its designed temperature window during high-load refuse and landfill compaction work. A worn or faulty cap that can no longer hold the rated pressure allows coolant to escape and temperatures to climb, increasing the risk of overheating, coolant loss, and potential engine damage over time.
