The Wacker Neuson Radiator is a genuine OEM component designed for the HI750GM, HI750GM HD, HI900DGM, and CUB700GM series indirect-fired air heaters. As a direct factory replacement, this radiator maintains the precise cooling and heat-transfer characteristics required to keep these diesel-powered heaters running at peak efficiency in demanding jobsite conditions. Wacker Neuson genuine OEM parts are engineered and validated to the same standards as the original unit, ensuring a drop-in fit with no guesswork. If your HI750GM or HI900DGM heater is running hot, losing efficiency, or showing signs of coolant leakage, part number is the correct OEM replacement to restore full operation.
Key Features
- OEM Cooling Capacity: — Engineered to the original heat-transfer and flow-rate specifications of the HI750GM and HI900DGM heater platforms, not a generic approximation.
- Drop-In Replacement: — Mounts using the factory bracket points and hose connections on compatible HI-series and CUB700GM heaters, so installation follows the original service procedure.
- Broad HI-Series Fitment: — Confirmed for HI750GM, HI750GM HD, HI900DGM (standard, surge brake, and electric configurations), and CUB700GM mobile indirect-fired air heaters.
- Sustained Heat Output: — A properly functioning radiator is essential for stable diesel combustion temperatures; a failing or clogged unit causes overheating faults, heater shutdowns, and reduced BTU output at the work site.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, carrying the full part number 5000182030 for straightforward verification against your machine's parts manual.
The radiator in an indirect-fired air heater manages the engine's coolant temperature by dissipating excess heat through its core as air passes over the fins. In a diesel-powered indirect heater like the HI750GM or HI900DGM, maintaining the correct engine operating temperature is critical — both for reliable ignition and for consistent, uninterrupted heat delivery to the work area. When the radiator becomes clogged, cracked, or develops a leak, the engine will overheat and the heater's safety systems will trigger a shutdown, cutting off heat to the space entirely.
