Wacker Neuson 5000175292 Radiator Flap Duct

The Wacker Neuson is a genuine OEM Radiator Flap Duct designed for the LTN6L, LTN6K, and LTN8K series light towers. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, the meets the exact specifications of the original component — no guesswork on fit or function. This part covers an extensive range of LTN-series configurations, including Kohler (Lombardini), Kubota, 50 Hz, 60 Hz, CE, Tier 4 Final, cold-weather, and racked variants. If your LTN light tower is running hot or airflow through the engine compartment is compromised, this is the component to address first.

Key Features

• Genuine OEM Airflow Integrity — Manufactured to Wacker Neuson's original tooling dimensions, ensuring the flap seats and seals correctly within the radiator duct housing — critical for maintaining directed cooling airflow across the engine.
• Drop-In Replacement — Matches the mounting points and profile of the factory duct flap on LTN6L, LTN6K, and LTN8K towers, installing the same way as the original part.
• Broad LTN-Series Coverage — Compatible with a wide range of LTN6L, LTN6K, LTN6LE, LTN8K, and V-series variants, including 50 Hz, 60 Hz, CE, Tier 4F, cold-weather, and racked configurations.
• Engine Cooling Protection — A correctly functioning duct flap channels airflow efficiently over the radiator; a damaged or missing flap allows heat to recirculate, leading to engine overtemperature events during extended lighting runs.
• Built for Extended Runtime Demands — Light towers operate for prolonged periods in demanding environments; this OEM component is built to the same durability standard as the part it replaces.

The radiator flap duct is a directed-airflow component within the engine enclosure of the light tower. Its job is to channel cooling air from the fan across the radiator core and prevent hot exhaust air from recirculating back into the intake path. When the flap is cracked, deformed, or missing entirely, the engine cooling system loses efficiency — coolant temperatures rise, and the engine may shut down on overheat protection during long overnight or continuous-run lighting operations. Replacing a worn duct flap restores proper thermal management and keeps the light tower running through extended shifts without interruption.
