The Bomag 05903878 Combination Radiator is a genuine OEM cooling component designed for BC 772 RB-3, BC 672 RB-3, and BC 772 RS-3 refuse and landfill compactors. Sourced directly from Bomag, this part carries the same engineering specs as the unit installed at the factory, ensuring a correct, complete fit with no adaptation needed. This combination radiator is built to handle the extreme thermal demands of heavy-cycle compaction work on landfill and refuse sites, where consistent engine cooling is critical to sustained machine output.
Key Features
- OEM Cooling Performance — engineered to the same core density, flow rate, and pressure tolerance as the original unit, delivering the full cooling capacity these high-output compactors require
- Direct-Fit Replacement — mounts to existing brackets and connects to OEM hose routing on BC 772 RB-3, BC 672 RB-3, and BC 772 RS-3 refuse and landfill compactors, matching the original part number 05903878 exactly
- Broad Model Coverage — fits BC 672 RB-3, BC 772 RB-3, and BC 772 RS-3 refuse and landfill compactors, covering multiple variants of Bomag's heavy-duty compaction line
- Protects Engine from Thermal Overload — a worn or blocked combination radiator causes coolant temperatures to spike, leading to power loss, engine shutdowns, and accelerated wear on internal components
- Genuine Bomag OEM Part — authentic OEM quality backed by Bomag's supply chain, giving you the confidence that this component meets the original design intent for your machine
A combination radiator manages engine coolant temperature by transferring heat from the coolant to the surrounding air as it circulates through the core. On heavy refuse and landfill compactors like the BC 772 RB-3 and BC 672 RB-3, the engine works at sustained high loads through long operating cycles, placing significant and continuous demand on the cooling system. When the combination radiator degrades — through core blockage, fin damage, or internal leaks — the engine runs hotter than its design range, which accelerates wear, triggers thermal protection shutdowns, and can cause costly engine damage if left unaddressed. Replacing a failing unit with a correct-spec genuine OEM part restores full cooling capacity and keeps the machine running at its intended performance level.
