The Multiquip EM98080 Lower Radiator Hose is a genuine OEM replacement designed for C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith concrete pumps. As a factory-sourced component, it meets the exact material and dimensional specifications required for proper cooling system function on these Mayco-series machines. Verify your model code against the fitment list — C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith — before ordering to ensure a correct match. DHS Equipment stocks this part to keep your concrete pump running at the right operating temperature.
Key Features
- Genuine OEM Construction — Produced to Multiquip's original material grade and wall-thickness specification, ensuring the hose handles the thermal cycling and pressure demands of a working concrete pump cooling circuit.
- Direct-Fit Lower Hose Routing — Molded to the correct length, diameter, and bend profile for the lower coolant port connection on C30HDNI, C30HDN, and related Zenith and Precision variants — seats correctly without trimming or adapters.
- Broad C30HD-Series Coverage — Confirmed fitment across C30HDNI, C30HDNI Precision, C30HDN, and C30HDNI Zenith concrete pump models, making it a single-source solution for fleets running multiple variants of this platform.
- Cooling System Integrity — A properly sealed lower hose maintains consistent coolant flow between the engine block and radiator. A cracked or swollen hose causes coolant loss, overheating, and unplanned shutdowns mid-pour.
- Verified Part Number — EM98080 is the Multiquip OEM part number; sourcing by this number eliminates substitution errors that can result in incorrect hose fitment or premature failure.
The lower radiator hose carries coolant from the bottom of the radiator back to the engine water pump inlet, completing the main coolant circulation loop. It operates under a combination of heat, pressure, and vibration throughout every work cycle, and the rubber compound must resist both internal coolant chemistry and external engine bay temperatures over time. When this hose deteriorates — swelling, cracking, or collapsing internally — coolant flow is restricted or lost entirely, causing the engine to overheat rapidly and potentially damaging the pump's power unit.
