The Wacker Neuson RD16 Radiator Cap is a genuine OEM component designed for the RD16-90, RD16-100, and CB14B series tandem rollers. Sourced directly from Wacker Neuson, this cap is engineered to the exact pressure specification required by these machines, ensuring the cooling system operates within its designed parameters. It fits a broad range of RD16 and CB14B configurations, including hydrostatic and standard vibratory variants used in soil and asphalt compaction applications.
Key Features
- Correct Pressure Rating for the Cooling System — Genuine OEM spec ensures the cap opens and seals at the precise pressure threshold the RD16 and CB14B cooling systems require.
- Direct-Fit OEM Replacement — Threads directly onto the original radiator filler neck with no modification — seats and seals exactly as the original.
- Broad RD16 and CB14B Compatibility — Verified fitment across RD16-90, RD16-100, CB14B-900, and CB14B-1000 configurations, including hydrostatic and standard vibratory roller variants.
- Protects Engine from Overheating — A failed or worn radiator cap allows coolant loss and pressure drop, leading to overheating and potential engine damage; this genuine replacement restores full system integrity.
- Cooling System Safety — Maintaining the correct cap pressure rating is essential to prevent coolant boil-over and pressure build-up in a sealed cooling circuit — particularly critical during continuous compaction work in warm conditions.
A radiator cap does more than seal the coolant reservoir — it regulates the pressure inside the entire cooling system. By holding the system at a specific pressure, it raises the boiling point of the coolant and allows the radiator overflow recovery circuit to function correctly. On tandem rollers like the RD16 and CB14B, which operate under sustained load during asphalt and soil compaction, maintaining proper coolant pressure is critical to preventing overheating cycles. A cap that has lost its sealing integrity or no longer holds the correct pressure will cause coolant to escape, the system to run under-pressure, and engine temperatures to climb — potentially causing costly engine damage if left unaddressed.
