The Wacker Neuson Radiator Fill Hole Plug is a genuine OEM component designed for the LTC4L and LTC4C series light towers, including standard, 50Hz, 50Hz CE, and Power Winch configurations. As a direct OEM replacement, is manufactured to the exact material and dimensional specifications of the original part, ensuring a proper seal at the radiator fill point. This plug fits multiple LTC4L and LTC4C variants, making it a go-to service part for fleet operators and technicians maintaining Wacker Neuson lighting equipment.
Key Features
- OEM-Grade Sealing Material — Manufactured to original specification, delivering the correct compression and chemical resistance needed to maintain a leak-free radiator fill point.
- Drop-In Installation — Threads directly into the existing radiator fill opening with no rework or adaptation to the housing required.
- Broad LTC4 Series Coverage — Confirmed fitment across LTC4L and LTC4C light tower variants, including standard, 50Hz, 50Hz CE, and Power Winch-equipped models.
- Coolant System Integrity — A damaged or missing fill plug allows coolant to escape and contaminants to enter, risking overheating and engine damage during extended light tower operation.
- Cooling System Safety — Maintains a properly pressurized and sealed cooling circuit, which is critical for safe continuous-duty operation of diesel-powered light towers running in demanding ambient conditions.
The radiator fill hole plug seals the coolant fill port on the radiator, keeping the cooling system pressurized and free from debris, dust, and moisture contamination. On a light tower running extended hours at a jobsite, a properly seated plug is essential to maintaining the correct coolant level and system pressure that protects the engine from overheating. When this plug is cracked, missing, or no longer sealing correctly, coolant loss and ingress of contaminants can lead to rapid engine temperature rise and unplanned shutdowns.
