The Multiquip V20405972 Upper Radiator Hose is a genuine OEM component designed for DCA150SSVU and DCA150SSVU-FEMA ultra-silent diesel generator models. As a direct OEM replacement, this hose meets the exact material and dimensional specifications set by Multiquip, ensuring a correct, secure connection within the cooling system. Sourced directly through authorized supply channels, V20405972 is the factory-specified part for these generator models. If your DCA150SSVU is showing signs of coolant leaks, overheating, or a deteriorating hose, this is the part to have on hand.
Key Features
- OEM-Grade Hose Construction — Manufactured to the exact wall thickness, inner diameter, and heat-resistant compound specified for the DCA150SSVU cooling circuit — not a generic hose adapted to fit.
- Direct Upper Hose Replacement — Connects the engine outlet to the radiator upper tank at the correct routing angle, seating cleanly against OEM clamp positions without trimming or adjustment.
- Confirmed Fitment — Verified for DCA150SSVU and DCA150SSVU-FEMA ultra-silent diesel generator models by Multiquip part number V20405972.
- Maintains Coolant Flow Integrity — A sound upper radiator hose sustains full coolant circulation between the engine and radiator; a cracked or collapsed hose restricts flow and can cause rapid engine overheating under load.
- Critical Cooling System Safety — On a high-output diesel generator running continuous or standby duty cycles, a failed upper hose can escalate quickly to thermal shutdown or engine damage — replacing at first sign of wear protects the entire powerplant.
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 coolant returns to the engine. It is one of the highest-temperature points in the cooling circuit and is subjected to constant pressure cycling, heat soak, and vibration. Over time, the hose material can harden, crack, or collapse internally, restricting coolant flow and leading to overheating — a serious risk on a generator running extended duty cycles. Replacing a worn upper hose promptly keeps the cooling system operating at full capacity and protects the diesel engine from heat-related damage.
