The Multiquip M3311501503 is a genuine OEM Surge Tank Hose designed for the DCA150SSJU4F3, DCA180SSJU4F3, and DCA220SSJU4F3 Super-Silent diesel generator series. As a direct OEM replacement, this hose is manufactured to the exact specifications required by these units, ensuring a correct, secure connection within the cooling circuit. Confirmed fitment covers both standard and 60Hz configurations across the DCA Super-Silent generator family.
Key Features
- Genuine OEM Construction — Manufactured to the precise material and dimensional specs of the original hose, ensuring correct pressure handling and flexibility within the cooling system.
- Direct-Fit Replacement — Engineered to connect exactly as the original, with matching end diameters and routing geometry for a straightforward swap with no rework to surrounding components.
- Broad Generator Series Coverage — Fits DCA150SSJU4F3, DCA180SSJU4F3, and DCA220SSJU4F3 Super-Silent generators, including both standard and 60Hz variants.
- Coolant System Integrity — A correctly seated surge tank hose maintains proper coolant flow and system pressure; a cracked or loose hose can lead to overheating and unplanned generator shutdown.
- Fuel System Adjacent Safety — Coolant hose integrity in enclosed super-silent generator enclosures is critical — a failing hose can direct coolant toward electrical and fuel components, creating additional hazards.
The surge tank hose connects the engine's coolant surge or overflow tank to the main cooling circuit, allowing the system to manage coolant expansion and contraction as the engine heats and cools. It plays a key role in maintaining stable operating temperatures by ensuring coolant can circulate correctly and that air is properly vented from the system. When this hose cracks, softens, or loses its seal, coolant levels drop, the engine runs hot, and the generator risks automatic shutdown or thermal damage during extended operation.
