When your cooling system needs attention, replacing with part number 05712134 keeps your machine operating within its designed thermal range.
Key Features
- OEM-Grade Coolant Regulation — manufactured to Bomag's original specifications, this thermostat opens and closes at the correct calibrated temperature to protect the engine under load
- Direct Drop-In Replacement — engineered to match the original housing dimensions and valve geometry, this thermostat installs into the existing cooling circuit without modification
- Broad BW-Series Coverage — fits a wide range of Bomag single drum rollers and tandem rollers including the BW 172 D-2, BW 177 D-4, BW 145 D-3, BW 124 DH-4, BW 151 AD-4, BW 154 AD-4, and C 815 C and C 825 C models, among others
- Engine Temperature Protection — a correctly functioning thermostat prevents both overheating and under-temperature running, both of which accelerate engine wear and reduce compaction efficiency
- Genuine Bomag OEM Part — supplied as an authentic Bomag component, part number 05712134 carries the same production quality as the original, giving you confidence in longevity and fitment accuracy
The thermostat is a valve within the engine cooling system that regulates coolant flow based on engine temperature. When the engine is cold, the thermostat stays closed, allowing the engine to reach its optimal operating temperature quickly. Once that threshold is reached, the valve opens to allow coolant to circulate through the radiator and shed excess heat. A failed or stuck thermostat can cause the engine to overheat — risking serious internal damage — or to run too cool, which leads to increased fuel consumption, oil contamination, and premature wear on cylinder components. Replacing a worn or faulty thermostat promptly is one of the most cost-effective ways to protect the engine in any Bomag roller.
