The Multiquip 12900444500 Radiator Assembly 3TNV76 AR16-2 is a genuine OEM cooling assembly designed for the AR16-2 asphalt ride-on roller. This is a direct OEM replacement sourced through the Multiquip parts network, ensuring the assembly matches the original design specifications of the 3TNV76-powered AR16-2. Verify your model and engine configuration against part number 12900444500 before ordering to confirm fitment.
Key Features
- OEM Cooling Integrity — Engineered to the same thermal capacity as the original unit, ensuring the 3TNV76 engine maintains proper operating temperature under sustained compaction loads.
- Direct-Fit Assembly — Mounts to the AR16-2 chassis using the original bracket points and hose connections, so installation follows the factory service procedure without modification to surrounding components.
- AR16-2 Specific — Matched to the AR16-2 asphalt ride-on roller and its 3TNV76 Yanmar diesel engine configuration; not a universal radiator.
- Overheating Prevention — A fully functional radiator assembly keeps coolant temperatures in range during continuous paving and compaction cycles, protecting the engine from heat-related damage and unplanned shutdowns.
- Genuine OEM Part — Supplied as an authentic Multiquip component, maintaining the same material grade, core construction, and tank sealing as the original assembly.
The radiator assembly is the primary heat exchanger in the AR16-2's liquid cooling system. It circulates engine coolant through a finned core where airflow draws heat away from the fluid before it returns to cool the engine block. When the radiator is cracked, corroded, or blocked, coolant temperatures rise rapidly, triggering thermal shutdowns or causing serious engine damage — particularly during high-load paving operations where the machine runs continuously with little idle time.
