Wacker Neuson 5000163143 Radiator Assembly Kit RD27

The Wacker Neuson Radiator Assembly Kit RD27 is a genuine OEM cooling assembly designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly through Wacker Neuson's authorized parts channel, this kit delivers an exact-match replacement that installs with no guesswork. It is engineered to the same specifications as the original unit, ensuring the cooling system performs as intended across demanding compaction cycles. If your RD27 series roller is running hot or showing signs of cooling system failure, this is the correct replacement assembly to restore full operation.

Key Features

• Genuine OEM Cooling Integrity — Built to Wacker Neuson's original thermal-management specifications, maintaining correct coolant flow rates and heat-rejection capacity for the RD27 power unit.
• Complete Assembly Kit — Supplied as a full radiator assembly kit for the RD27, so all core components arrive together and install as a single matched unit.
• Verified Fitment for RD27 Series — Confirmed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, eliminating compatibility uncertainty before the part arrives on site.
• Sustained Engine Protection — A properly functioning radiator keeps the engine within its safe operating temperature range; a failed or restricted unit risks overheating and accelerated engine wear during extended compaction runs.
• Direct-Swap Replacement — Mounts to the existing OEM mounting points on the RD27 chassis, supporting a straightforward swap without fabrication or bracket modification.

The radiator assembly is the primary heat exchanger responsible for dissipating engine heat generated during operation. Coolant circulates through the engine block, absorbs heat, and then passes through the radiator core where airflow carries that heat away before the cooled fluid returns to the engine. On a walk-behind tandem roller like the RD27, which operates under sustained load during asphalt and soil compaction, consistent cooling is critical to protecting the engine and hydraulic system. When the radiator becomes damaged, clogged, or begins to leak, coolant temperatures rise rapidly, triggering overheating conditions that can cause engine shutdown or long-term internal damage if left unaddressed.
