The Wacker Neuson 5100018835 is a genuine OEM Radiator Cap designed for the LTN6K and LTN8K series light towers. This includes standard, cold weather, Tier 4F, and variable-output (LTN6K-V, LTN8K-V, LTN6K-V S, LTN8K-V S) configurations across a wide range of machine numbers. As a direct OEM replacement, the 5100018835 is built to the exact pressure rating and sealing specification required by the Kubota-powered cooling systems used in these towers, ensuring proper fit with no guesswork on compatibility.
Key Features
- Correct Pressure Rating for LTN Cooling Systems — Engineered to the precise relief pressure specification of LTN6K and LTN8K cooling systems, ensuring the coolant operates within the designed temperature range.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this cap meets the same material and sealing standards as the part originally installed on your light tower.
- Broad LTN Series Compatibility — Fits a wide range of LTN6K and LTN8K configurations including standard, cold weather, Tier 4F, 60 Hz, and 120/240V variable-output models.
- Seals Cooling System Against Pressure Loss — A worn or failed radiator cap allows coolant to escape and disrupts system pressure, leading to overheating — replacing it promptly protects the engine and keeps the tower running through long overnight shifts.
- Drop-In Replacement — Installs directly onto the existing radiator filler neck with no additional hardware or adaptation required.
A radiator cap does more than seal the cooling system — it regulates the pressure inside the coolant circuit, which raises the boiling point of the coolant and allows the engine to operate efficiently at higher temperatures. When the cap's pressure valve or sealing gasket wears out, coolant can boil over, escape through the overflow, or cause air pockets to form in the system. On a light tower running through an extended overnight job, a failed radiator cap can quickly lead to engine overheating and unexpected downtime. Replacing it with the correct OEM cap, like the Wacker Neuson 5100018835, restores the system to its intended operating pressure and protects the engine long-term.
