The Bomag 05903499 Radiator Cap is a genuine OEM component designed for BC-series refuse and landfill compactors. Built to the same specifications as the original, this radiator cap delivers an exact pressure-rated seal for the cooling system on machines including 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. As a direct OEM replacement sourced from Bomag, part number 05903499 ensures the cooling system maintains the correct operating pressure without adaptation or guesswork.
Key Features
- OEM Pressure Rating — manufactured to the original pressure specification, maintaining the precise relief threshold your cooling system depends on for safe, consistent temperature control
- Direct Drop-In Fitment — matches the original cap's thread pitch, sealing surface, and valve geometry for a straightforward install on the cooling system filler neck
- 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 Integrity — a correctly rated cap keeps coolant from boiling off under load, protecting the engine from heat-related damage during heavy compaction cycles
- Pressurized System Safety — the OEM pressure relief valve opens at the engineered threshold, preventing dangerous over-pressurization in the cooling circuit
The radiator cap does more than close the coolant reservoir — it maintains the system pressure that raises the coolant's boiling point and keeps the engine running at a stable operating temperature. A worn or incorrect cap loses its ability to hold pressure, allowing coolant to escape as steam, which can lead to overheating and engine damage in demanding landfill and refuse compaction environments. Replacing a faulty cap with a genuine OEM part like the Bomag 05903499 restores the sealed, pressurized cooling circuit the machine was engineered to run on.
