The Wacker Neuson is a genuine OEM Radiator Bottom Hose Rd27 designed for the RD27-100 and RD27-120 tandem roller series. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional specifications of the original component installed at the factory. It is compatible across multiple build configurations of the RD27 platform, including Pro, Basic, and T4F-compliant variants. When your cooling system needs attention, replacing with part number ensures a proper, leak-free connection between the radiator and the engine cooling circuit.
Key Features
- Genuine OEM Coolant-Grade Construction — Manufactured from the same heat- and pressure-resistant hose material as the original, maintaining the correct burst and flex ratings for the RD27 cooling circuit.
- Direct Bottom-Port Fit — Sized and shaped to connect directly to the lower radiator outlet on RD27 machines, with correct end diameters and hose geometry for a secure clamp-down installation.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 configurations across Pro, Basic, and T4F emission-tier variants, covering a wide range of serial number ranges within the RD27 platform.
- Sustained Engine Temperature Control — A properly seated lower radiator hose maintains full coolant flow from the engine block back to the radiator; a cracked or collapsed hose restricts circulation and risks overheating during continuous compaction passes.
- Cooling System Integrity — As a pressurized component in the engine cooling circuit, using a correctly rated OEM hose helps prevent coolant loss and the risk of unplanned shutdowns on the compaction site.
The radiator bottom hose carries cooled coolant from the lower outlet of the radiator back to the engine water pump, completing the closed-loop cooling circuit. On a ride-on tandem roller like the RD27, where the engine runs under sustained load during compaction passes, consistent coolant flow through this hose is essential to keeping operating temperatures within the safe range. A hose that has cracked, softened, or collapsed at the lower connection point will reduce coolant circulation, cause the engine temperature to climb, and can ultimately trigger a thermal shutdown or accelerate engine wear if left unaddressed.
