Wacker Neuson 5100053887 Radiator Top Tank MG ML

The Wacker Neuson Radiator Top Tank MG ML is a genuine OEM component designed for the G70 and G100 series portable generators. This factory-sourced tank is a direct replacement for the original part, covering Standard, Cold Weather, Custom, and URI HVAC T4F configurations across both the G70 and G100 generator families. As a genuine Wacker Neuson part, the is manufactured to the same specifications as the original, ensuring a correct fit and proper cooling system function. Keep your generator's cooling circuit operating as intended by replacing worn or damaged tanks with an authentic OEM component.

Key Features

• OEM Cooling System Integrity — Manufactured to the same material and dimensional specs as the original tank, ensuring correct coolant capacity and sealing performance at the radiator top.
• Drop-In Replacement — Mounts directly to the existing radiator assembly using the original hardware and connections, with no rework to fittings or hose routing.
• Broad G70 and G100 Coverage — Fits multiple G70 and G100 generator configurations including Standard, Cold Weather, Custom, URI HVAC, and URI CW T4F variants.
• Protects Engine Cooling Efficiency — A sound top tank maintains proper coolant flow and system pressure; a cracked or leaking tank leads to overheating and unplanned generator shutdowns under load.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so the part number, material grade, and fitment are verified against the original engineering specification.

The radiator top tank forms the upper reservoir of the generator's liquid cooling circuit, collecting hot coolant returning from the engine before it passes through the radiator core to be cooled. It also houses or connects to key fittings such as the coolant fill point, overflow connection, and upper hose outlet. When the top tank cracks, warps, or develops a leak — whether from age, impact, or pressure fatigue — coolant loss occurs rapidly, coolant temperature climbs, and the engine is at risk of thermal overload. Replacing a compromised top tank promptly restores the sealed cooling circuit and prevents the cascade of damage that sustained overheating can cause to a generator engine.
