The Wacker Neuson Thermostat is a genuine OEM thermostat designed for the RC110 and RC110P single-drum soil compactors. This OEM part is sourced directly through Wacker Neuson's authorized parts network, ensuring it meets the exact specifications required for correct engine cooling system operation. Fitment covers the full RC110 and RC110P model range, including ROPS and CAB configurations. Whether you're servicing a standard RC110, an RC110P, or a US-spec ROPS or CAB variant, part number is the correct replacement.
Key Features
- Exact OEM Specification: — Calibrated to the precise opening temperature required by the RC110 series engine, ensuring the cooling circuit activates at the correct threshold — not too early, not too late.
- Drop-In Compatibility: — Replaces the original thermostat housing installation on RC110 and RC110P models; fits the existing housing without modification to coolant lines or fittings.
- Broad RC110 Series Coverage: — Confirmed fitment across RC110, RC110P, RC110 US ROPS, RC110P US ROPS, RC110 US CAB, and RC110P US CAB single-drum soil compactors.
- Protects Engine from Thermal Stress: — A correctly functioning thermostat keeps the engine operating within its designed temperature window, protecting against overheating under sustained compaction loads and slow warm-up damage in cold starts.
- Fuel Efficiency and Output: — Proper coolant temperature regulation allows the engine to reach and maintain its optimal combustion range, supporting consistent compaction force and efficient fuel consumption during large-area soil compaction passes.
The thermostat is a valve in the engine's coolant circuit that regulates operating temperature by controlling coolant flow to the radiator. When the engine is cold, the thermostat stays closed, allowing the engine to warm up quickly. Once the coolant reaches the correct operating temperature, it opens and routes coolant through the radiator to shed heat. On a heavy-duty machine like the RC110 single-drum compactor — working through continuous passes on large soil compaction sites — a failed or stuck thermostat can cause the engine to run too hot or too cold, both of which accelerate wear, reduce power output, and can lead to costly engine damage if left unaddressed.
