The Multiquip EM98079 Upper Radiator Hose is a genuine OEM replacement designed for C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith series concrete pumps. As a factory-sourced component, EM98079 is manufactured to the exact dimensions and material specifications of the original part, ensuring a correct, leak-free connection between the engine and radiator. This hose is a direct fit for the Mayco concrete pump lineup, covering multiple engine variants within the C30HD family.
Key Features
- Genuine OEM Construction — Molded to the exact internal diameter, wall thickness, and bend geometry of the original hose, maintaining proper coolant flow and pressure containment in concrete pump cooling systems.
- Direct-Fit Replacement — Seats onto the existing radiator and engine coolant outlets without trimming or adapting, matching the original routing of the C30HD series cooling circuit.
- Broad C30HD Family Coverage — Compatible with C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith concrete pump models, covering both Nissan and Zenith engine configurations.
- Coolant System Integrity — A properly seated upper radiator hose maintains the closed-loop pressure needed for effective engine temperature regulation, preventing overheating during high-output pumping operations.
- Heat and Pressure Resistance — Built from hose material rated to withstand the thermal cycling and coolant pressures generated by concrete pump engines operating in demanding pour environments.
The upper radiator hose carries hot coolant from the engine's thermostat housing to the top of the radiator, where heat is dissipated before the cooled fluid returns to the engine. In a concrete pump like the C30HD series, the engine runs under sustained load, making a sound, leak-free hose critical to keeping operating temperatures in range. A cracked, collapsed, or leaking upper hose disrupts coolant circulation, leading to rapid engine overheating and potential damage to seals, gaskets, and internal engine components.
