Multiquip B0311500803 Upper Radiator Hose - OEM Replacement Part for Generator Cooling System

This upper radiator hose connects the engine to the radiator on Multiquip WhisperWatt series super silent generators, ensuring proper coolant flow through the 1.85-gallon cooling system. The radiator hose is a critical component in maintaining optimal engine operating temperature for the Kubota D1503-M diesel engine, which produces 18.4 hp at 1,800 rpm and requires consistent cooling to prevent overheating and wet stacking conditions.

Designed specifically for 60Hz generator applications, this upper hose handles the thermal stress of continuous operation under varying load conditions. The cooling system must maintain proper pressure and flow to support fuel consumption rates ranging from 0.44 gallons per hour at 1/4 load up to 0.98 gallons per hour at full load. A failing radiator hose can lead to coolant loss, overheating, and potential engine damage—symptoms include visible coolant leaks, soft or cracked hose material, or engine temperature warnings.

Compatible with the following Multiquip generator models:
