The Multiquip V20412278 Upper Radiator Hose is a genuine OEM component designed for the DCA100SSVU ultra-silent diesel generator. As a factory-sourced part, it meets the exact material and dimensional specifications set by Multiquip, ensuring a proper seal and correct coolant flow through the engine's cooling circuit. This hose is a direct match for DCA100SSVU units, making it the straightforward choice when the original hose shows signs of cracking, softening, or coolant weeping at the connection points. DHS Equipment stocks this part ready to ship, so you can get your generator back online without extended delays.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact compound and wall-thickness specifications for the DCA100SSVU cooling system, not a generic hose cut to size.
- Correct Molded Profile — Pre-formed to the precise routing angle of the upper radiator connection, so it seats cleanly against both the radiator neck and engine outlet without forcing or reshaping.
- Confirmed Fitment — Verified for the DCA100SSVU ultra-silent diesel generator series using Multiquip's OEM parts catalog.
- Cooling System Integrity — A correctly seated upper hose maintains system pressure and stable coolant circulation, protecting the engine from thermal stress during sustained generator operation.
- Fuel and Heat Resistance — OEM hose material is formulated to withstand the elevated underhood temperatures and coolant chemistry of continuous-duty diesel generator use.
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 cycles back through the engine. It is one of the highest-pressure and highest-temperature points in the cooling circuit, making hose condition critical to overall engine health. A hose that has softened, cracked, or begun to collapse under suction will allow coolant loss or restricted flow, which can push coolant temperatures into the danger zone and trigger shutdown on a working generator.
