The Bomag 05904187 Water and Oil Radiator is a genuine OEM cooling component designed for Bomag BW 177 and BW 145 series single drum rollers, as well as the BW 11 RH-5 pneumatic tyred roller. Sourced directly from Bomag, this radiator delivers an exact fit and correct cooling capacity for the machines it serves — no guesswork on compatibility. It covers a broad range of generation-5 models including the BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, BW 177BVC-5, BW 177-5, BW 145 D-5, BW 145 DH-5, and BW 145 PDH-5, making it the right call for fleet operators running multiple variants.
Key Features
- Genuine OEM Cooling Performance — built to Bomag's original specifications for coolant flow rate and oil-side heat rejection, ensuring the engine and hydraulic system stay within their designed operating temperature ranges
- Dual-Circuit Design — combines water and oil cooling in a single unit, matching the integrated layout of the original installation for a straightforward drop-in replacement
- Broad Generation-5 Coverage — fits BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, BW 177BVC-5, BW 177-5, BW 145 D-5, BW 145 DH-5, BW 145 PDH-5 single drum rollers and BW 11 RH-5 pneumatic tyred rollers
- Protects Engine and Hydraulics — a degraded or leaking radiator leads to overheating, power loss, and accelerated wear across the drivetrain; replacing it promptly restores full thermal protection
- Verified Part Number — order with confidence using Bomag part number 05904187, cross-referenced to the machines listed above for accurate fitment
The water and oil radiator serves as the central heat-exchange component in the machine's cooling circuit. The water side dissipates engine combustion heat by circulating coolant through the core, while the oil side manages hydraulic fluid temperature — keeping it in the range needed for consistent compaction force and drive response. When this radiator degrades, cracks, or becomes blocked, both systems are compromised: engine overheating and hydraulic sluggishness follow quickly, often forcing a costly unplanned shutdown on the job.
