Wacker Neuson 5000179989 Kubota Light Tower Radiator

The Wacker Neuson is a genuine OEM Kubota Light Tower Radiator designed for the LTN6K, LTN8K, LTN6K-V S, LTN8K-V S, LTV6K, and LTV8K series light towers. As a direct Wacker Neuson OEM component, part is manufactured to the same specification as the original unit fitted at the factory, ensuring correct coolant flow rates and a drop-in connection to existing hose and mounting points. This radiator covers an extensive range of configurations across the LTN and LTV families, including standard, cold weather, Tier 4 Final, and 120/240V variants — so double-check your model number and serial tag before ordering to confirm the right fit for your specific machine.

Key Features

• OEM Core Construction — Built to Wacker Neuson OEM specification with correct tube-and-fin geometry for the Kubota engine used across LTN and LTV light tower platforms, maintaining the heat-rejection capacity the engine requires.
• Direct-Mount Replacement — Hose connections, mounting bracket points, and overall envelope dimensions match the original, allowing the unit to seat and secure without cutting or adapting existing plumbing.
• Broad LTN and LTV Series Coverage — Fits LTN6K, LTN6K-V S, LTN6K-LT, LTN8K, LTN8K-V S, LTN8K-LT, LTV6K, and LTV8K configurations, including standard, cold-weather, Tier 4 Final, and multi-voltage variants.
• Sustained Engine Operating Temperature — A properly functioning radiator keeps the Kubota engine within its designed coolant temperature range during extended night-shift or continuous-runtime operations; a failing unit leads to overheating shutdowns and potential engine damage.
• Cooling System Integrity — Using the correct OEM radiator maintains the sealed-system pressure rating and coolant compatibility required by the Kubota engine, which is particularly important in cold-weather Tier 4 Final configurations where thermal management tolerances are tighter.

The radiator is the core component of the engine's liquid cooling system. It dissipates heat absorbed from the engine coolant by passing it through a network of tubes and fins where airflow — drawn by the cooling fan — carries that heat away. In a light tower application, where the Kubota engine may run continuously for many hours at a stretch, the radiator works constantly to prevent the engine from exceeding safe operating temperatures. When a radiator degrades through core damage, internal scaling, or external blockage, coolant temperatures climb, the engine's thermal protection system triggers a shutdown, and left unaddressed, sustained overheating can cause permanent internal engine damage.
