The Wacker Neuson Radiator Cap is a genuine OEM component designed for the RT and RTL/RTK series remote-controlled vibratory trench rollers. This cap is a direct-fit replacement sourced from Wacker Neuson, covering a wide range of SC2 and SC3 generation models including the RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, RTKx-SC3, RTx-SC2, and HTC15 trench rollers. As a genuine OEM part, the meets the exact pressure rating and sealing specification called for in the original design, ensuring the cooling system performs as intended across all listed platforms.
Key Features
- Correct Pressure Rating for the Cooling System — Engineered to the precise pressure specification of the original cap, maintaining proper coolant pressurization across the RT and RTL/RTK trench roller cooling circuits.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this cap carries the same part number and sealing construction as the unit installed at the factory.
- Broad Trench Roller Fitment — Compatible with RT56-SC, RT82-SC, RT82-SC2, RTx-SC2, RTLx-SC3, RTKx-SC3, RTL82-SC3, RTK82-SC3, and HTC15 models across SC, SC2, and SC3 generations.
- Seals the Cooling System Reliably — The cap's pressure-relief valve and sealing gasket work together to prevent coolant loss and protect the engine from overheating during demanding trench compaction cycles.
- Drop-In Installation — Threads directly onto the original radiator filler neck with no modification to the cooling system — no adapters or additional hardware required.
- Overheating Prevention — A worn or damaged radiator cap that fails to hold pressure can cause coolant boilover and engine thermal stress; replacing it with part 5000164350 restores full system integrity.
The radiator cap serves as the pressure-regulating closure for the cooling system. It maintains a set pressure level within the cooling circuit, which raises the boiling point of the coolant and allows the engine to run at its designed operating temperature without coolant loss. When the cap's internal spring or sealing gasket wears out, the system can no longer hold pressure — leading to coolant boilover, erratic temperature readings, and potential engine damage during operation. On remote-controlled trench rollers like the RT and RTL/RTK series, where the engine works hard in confined trench environments, a properly functioning radiator cap is a straightforward but critical part of engine protection.
