The Wacker Neuson Overflow Bottle is a genuine OEM component designed for the RD16 tandem roller series, RT56 and RT82 vibratory trench roller series, RTLx and RTKx SC3 trench rollers, and select DPU130Le reversible vibratory plate compactors. As a direct factory replacement, part is manufactured to the exact specifications of the original, ensuring a correct, hassle-free installation. This overflow bottle is compatible across a wide range of Wacker Neuson compaction equipment, making it a versatile stocking part for fleets running multiple machine families. Confirming your model number against the fitment list before ordering is always recommended.
Key Features
- Genuine OEM Construction: — Molded to the original wall thickness and port dimensions, so fluid capacity and pressure behavior match what the cooling system was engineered to handle.
- Direct-Fit Installation: — Matches the factory mounting points and hose connections on compatible RD16, RT56-SC, RT82-SC, RTLx-SC3, RTKx-SC3, and DPU130Le models for a straightforward swap.
- Broad Fitment Across Compaction Families: — A single part number covers tandem rollers, remote-controlled trench rollers, and reversible plate compactors, simplifying parts inventory management.
- Cooling System Integrity: — A properly functioning overflow bottle maintains correct coolant volume and vents trapped air, preventing overheating under sustained compaction loads.
- OEM Part Number Assurance: — Sourced directly through the Wacker Neuson parts network; part number 5000157209 is traceable to the original equipment manufacturer for accurate ordering.
The overflow bottle — also called a coolant expansion or recovery tank — serves as the pressure-relief reservoir for the engine's cooling system. As coolant heats up and expands during operation, excess fluid is directed into the overflow bottle; when the engine cools, that fluid is drawn back into the system to maintain the correct fill level. A cracked, collapsed, or missing overflow bottle disrupts this cycle, leading to coolant loss, inconsistent system pressure, and the risk of engine overheating on the worksite.
