The Wacker Neuson Radiator Hose Upper is a genuine OEM radiator hose upper designed for the HI1000 Indirect Air Heater series, including HI1000DGM and HI1000 models. Sourced directly from Wacker Neuson, this part is manufactured to the same specification as the original component fitted at the factory. It is confirmed compatible across multiple HI1000DGM configurations, including Electric Break and Surge Brake variants, as well as the standard HI1000 heater.
Key Features
- OEM Coolant Path Integrity — Manufactured to original hose diameter and wall thickness specs, ensuring a leak-free seal at both connection points with no risk of pressure drop across the cooling circuit.
- Direct-Fit Replacement — Engineered to the exact routing geometry of the original upper hose, seating correctly on the heater's coolant outlets without trimming or reshaping.
- Broad HI1000 Series Coverage — Fits HI1000DGM Electric Break, HI1000DGM Surge Brake, and standard HI1000 Indirect Air Heater models under a single part number.
- Sustained Heat Output — A fully sealed upper hose maintains correct coolant flow through the heat exchanger, allowing the heater to reach and hold target output temperatures consistently during operation.
- Combustion System Safety — Coolant hose failure on an indirect-fired heater can cause rapid overheating and potential shutdown or damage to heat exchanger components; replacing with a genuine OEM hose restores safe operating margins.
The upper radiator hose carries heated coolant from the engine or heat source to the top of the heat exchanger, forming the high-side leg of the cooling circuit. On indirect air heaters like the HI1000 series, maintaining this flow path is essential — any leak or collapse in the hose directly reduces heating efficiency and can trigger thermal protection shutdowns. A worn or cracked hose that goes unaddressed risks overheating the burner assembly and cutting short the heater's working life.
