The Wacker Neuson is a genuine OEM Coolant Hose 3/8 ID x 2000mm designed for the G70, G100, and G120 portable generator series. As a direct OEM replacement, part is manufactured to the exact dimensions and material specifications required for proper coolant flow in these Tier 4i generator models. It covers a wide range of G70, G100, and G120 configurations — including Standard, Custom, Cold Weather, Extended Run, Hertz, and URI HVAC variants — so you can order with confidence regardless of your machine's configuration. Using the correct OEM hose ensures a leak-free connection and helps maintain the cooling system integrity your generator depends on in demanding job conditions.
Key Features
- OEM-Spec Hose Material — Manufactured to the exact inner diameter and 2000mm length specified for the G70, G100, and G120 cooling circuits, ensuring proper flow rate and pressure retention.
- Direct-Fit Replacement — Routes and connects exactly as the original, with no trimming or adapting required to seat correctly in the generator's coolant circuit.
- Broad G-Series Compatibility — Fits G70, G100, and G120 Tier 4i generators across Standard, Custom, Cold Weather, Extended Run, Hertz, and URI HVAC configurations.
- Coolant System Integrity — A correctly sized, undamaged hose keeps coolant circulating at the right pressure and volume; a cracked or ill-fitting hose risks overheating and unplanned generator shutdowns.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number (5200012150) referenced in the factory parts documentation for these generator models.
The coolant hose routes engine coolant between the engine, radiator, and associated cooling components, keeping the generator's operating temperature within the safe range during extended run periods. At 2000mm in length and 3/8-inch inner diameter, this hose is sized specifically to reach and seal the connection points designed into the G70, G100, and G120 generator frames. When a coolant hose cracks, swells, or develops a leak, the engine loses coolant pressure and risks overheating — leading to automatic shutdowns or, if left unaddressed, serious engine damage. Replacing a worn hose promptly with the correct OEM part restores full cooling performance and keeps the generator running reliably.
