Sourced directly from Bomag, this thermostat meets the exact specifications of the original part it replaces, ensuring correct coolant regulation from the first installation. Confirmed fitment across the full range of BW 213 and BW 214 D-3-series single drum rollers makes part number 31400667 a straightforward, confidence-inspiring choice for service technicians and fleet managers alike.
Key Features
- Genuine OEM Coolant Control — manufactured to Bomag's exact opening temperature and flow specifications, so the engine reaches and holds its correct operating temperature without running hot or cold
- Direct Drop-In Installation — matches the original housing seat, bypass port, and connection dimensions of the factory thermostat for a clean, leak-free swap with standard tools
- Verified Fitment — confirmed for BW 213 D-3, BW211D 3, BW 213 DH-3, BW 213 PDH-3, and BW 214 DH-3 single drum rollers; part number 31400667 cross-references directly to the OEM catalog
- Protects Engine from Thermal Stress — a failing thermostat causes chronic overheating or prolonged cold running, both of which accelerate wear on pistons, liners, and bearings; a correctly functioning unit keeps thermal cycles within safe limits
- Cooling System Integrity — as a genuine Bomag part, this thermostat is validated to work in concert with the roller's OEM water pump and radiator, maintaining full cooling circuit balance under sustained compaction loads
The thermostat is the gatekeeper of the engine's cooling system. It remains closed when the engine is cold, allowing coolant to circulate only within the engine block so the oil and combustion temperatures rise to their efficient operating range as quickly as possible. Once the engine reaches its target temperature, the thermostat opens progressively, routing coolant through the radiator to shed excess heat. When a thermostat sticks closed, coolant cannot flow to the radiator and the engine overheats rapidly; when it sticks open, the engine runs chronically cold, increasing fuel consumption, oil dilution, and internal wear. Replacing a faulty thermostat promptly restores proper thermal management and protects every other component in the cooling circuit.
