Wacker Neuson 5000163977 RD16 Radiator Outlet to Reservoir Hose

The Wacker Neuson is a genuine OEM RD16 Radiator Outlet to Reservoir Hose designed for the RD16-90 and RD16-100 series tandem vibratory rollers. Sourced directly from Wacker Neuson, this hose matches the original routing, diameter, and end fittings of the factory-installed component — no trimming or adapting required at installation. It is confirmed compatible across multiple RD16-90 and RD16-100 configurations, including standard hydrostatic and IRH variants. When your coolant circuit needs attention, replacing the with the correct OEM hose keeps the cooling system performing as the machine was designed to run.

Key Features

• OEM Coolant Hose Construction — Manufactured to Wacker Neuson's original material and wall-thickness specification, ensuring the hose withstands the operating temperature and pressure of the RD16 cooling circuit.
• Direct-Routing Replacement — Pre-formed to the exact routing path between the radiator outlet and the coolant reservoir on RD16 series rollers, so the hose seats correctly against factory clamp positions without reshaping.
• Broad RD16 Series Coverage — Fits RD16-90 Vibratory Roller, RD16-90 Hydrostatic Vibratory Roller (IRH), RD16-90 Tandem Roller, and RD16-100 Hydrostatic Vibratory Roller configurations.
• Protects Engine Temperature Regulation — A degraded or leaking outlet hose disrupts coolant flow between the radiator and reservoir, leading to overheating and unplanned machine stops during compaction operations.
• Genuine Wacker Neuson Part — Part number 5000163977 is an authentic OEM component, giving you confidence that the part you receive matches the original in every dimension critical to a sealed, leak-free cooling circuit.

The radiator outlet to reservoir hose carries cooled coolant from the radiator outlet to the coolant reservoir, forming a key link in the engine's closed-loop cooling circuit. On tandem rollers like the RD16 series, maintaining consistent coolant flow is essential to keeping drum drive and engine systems operating within safe temperature ranges during sustained compaction work. When this hose cracks, softens, or develops a leak, coolant loss can occur gradually — often undetected until an overheat condition develops — making timely replacement important for protecting the machine's engine.
