The Wacker Neuson Radiator is a genuine OEM Radiator designed for the LTN4Y and LTN5Y series light towers, including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. As a direct-from-manufacturer component, it meets the same construction and performance standards as the part originally installed at the factory. Sourced through authorized Wacker Neuson supply channels, part number is a straightforward drop-in replacement that restores proper engine cooling to your light tower.
Key Features
- OEM Cooling Capacity: — Built to the exact thermal transfer specifications of the original, ensuring the engine stays within its operating temperature range under continuous load.
- Direct-Fit Installation: — Matches the original mounting points, hose connections, and core dimensions of the LTN4Y and LTN5Y series, so the swap is clean and straightforward.
- Broad LTN Series Coverage: — Confirmed fitment across the full LTN4Y and LTN5Y family, including SA, RH, CH, UK, 60 Hz, 120V/60Hz, Yp, Ypa, Ypk, and Yp HD variants.
- Prevents Overheating Shutdowns: — A degraded or leaking radiator leads to thermal cutouts and unplanned shutdowns on the job; replacing it with a correctly rated unit keeps your tower running through the night.
- Genuine Wacker Neuson Part: — Supplied as genuine OEM, meaning the materials, core density, and pressure ratings match what Wacker Neuson specified for this engine cooling system — no guesswork on compatibility.
The radiator is the engine's primary heat exchanger, circulating coolant through the engine block to absorb heat and then passing that hot coolant through the radiator core, where airflow dissipates the heat before the coolant loops back. In a light tower running long overnight shifts, sustained engine load makes consistent cooling critical — a cracked core, blocked passages, or a leaking tank will cause coolant loss and rapid overheating. Left unaddressed, a failing radiator can lead to engine damage that far exceeds the cost of the part itself, making timely replacement one of the most important maintenance decisions on any tower.
