The Wacker Neuson 5100012351 is a genuine OEM Cooling Water Hose designed for the RD18-80 and RD18-100 series tandem rollers. Sourced directly through Wacker Neuson's authorized parts program, this hose is manufactured to the exact material and dimensional specifications of the original component. It fits across the full RD18 family, including RD18-80, RD18-80 SE, RD18-100, RD18-100 C, RD18-100c, and their respective regional and revision variants. Replacing a worn or damaged cooling water hose with the correct OEM part helps maintain proper coolant flow and protects engine components from heat-related damage.
Key Features
- OEM-Grade Hose Material — Manufactured to the original pressure and temperature tolerances required by the RD18 cooling system, ensuring the hose seats and seals correctly at both connection points.
- Direct-Fit Replacement — Matches the original hose routing, end diameter, and length so installation follows the same procedure as the factory component with no trimming or adapting.
- Broad RD18 Series Coverage — Compatible with RD18-80, RD18-80 SE, RD18-100, RD18-100 C, RD18-100c, and associated revision variants across US, SE, and standard configurations.
- Protects Engine Cooling Integrity — A correctly functioning cooling water hose maintains consistent coolant circulation; a cracked or collapsed hose can cause overheating and unplanned engine shutdowns during compaction operations.
- Genuine Wacker Neuson OEM Part — Part number 5100012351 is an authorized Wacker Neuson replacement, giving you confidence that the part matches the original design intent for the RD18 tandem roller platform.
The cooling water hose is a critical link in the engine's liquid cooling circuit, carrying coolant between the engine block, radiator, and associated cooling components. It maintains the flow of temperature-regulated coolant that prevents the engine from overheating during sustained operation — a particular concern on ride-on tandem rollers working continuous asphalt passes. When a cooling water hose degrades, cracks, or loses its seal at either connection point, coolant loss can occur rapidly, leading to elevated engine temperatures, potential engine damage, and forced shutdowns on the worksite.
