The Wacker Neuson Radiator Bottom Hose is a genuine OEM component designed for RD27-100 and RD27-120 hydrostatic vibratory tandem rollers. Sourced directly from Wacker Neuson, this hose meets the exact routing, diameter, and material specifications of the original part. It is confirmed compatible across multiple machine configurations within the RD27-100 and RD27-120 series. When your cooling system hose shows signs of cracking, softening, or leaking, replacing it with part restores the integrity of the entire coolant circuit.
Key Features
- Genuine OEM Coolant Hose Construction — Manufactured to Wacker Neuson's original material and pressure specifications, ensuring the hose resists heat cycling and coolant degradation over time.
- Direct-Fit Lower Radiator Connection — Matches the original lower radiator outlet and engine inlet port geometry on RD27-series rollers, allowing a straightforward hose-clamp installation without trimming or adapting.
- Confirmed RD27-100 and RD27-120 Compatibility — Verified fitment for RD27-100 and RD27-120 hydrostatic vibratory tandem rollers across multiple machine configurations in both series.
- Coolant Flow Integrity — A sound lower radiator hose maintains proper coolant volume and flow rate to the engine; a collapsed or cracked hose restricts circulation and can lead to rapid overheating under load.
The radiator bottom hose carries coolant from the lower outlet of the radiator back to the engine's water pump inlet, completing the primary cooling loop. It operates under the suction side of the water pump, which means a soft or compromised hose can partially collapse at speed, restricting coolant flow even when there are no visible external leaks. On a compaction machine like the RD27-series tandem roller — which works under sustained load in hot conditions — a failed lower hose can result in rapid engine overheating and unplanned downtime. Replacing a worn hose at the first sign of deterioration is one of the most straightforward ways to protect the engine and keep the cooling system operating as intended.
