The Multiquip M5317200003 is a genuine OEM Surge Tank Hose designed for the DCA300SSJU4F series Super-Silent and Diesel Powered generators. As a factory-sourced component, this hose matches the original material grade, diameter, and routing geometry of the production part, ensuring a correct installation without modification. It is confirmed compatible with DCA300SSJU4F, DCA300SSJU4F2, DCA300SSJU4F3, and DCA300SSJU4F3PD 60Hz variants. Keeping this hose in sound condition is essential to maintaining proper coolant circulation and protecting the engine from heat-related damage during extended generator operation.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional specification as the original hose, preserving correct coolant flow characteristics for the DCA300SSJU4F cooling system.
- Direct-Fit Replacement — Matches the original hose routing, end fittings, and length so it seats correctly against the surge tank and coolant circuit connections without trimming or adapting.
- Broad Series Compatibility — Fits DCA300SSJU4F, DCA300SSJU4F2, DCA300SSJU4F3, and DCA300SSJU4F3PD Super-Silent and Diesel Powered generator variants operating at 60Hz.
- Coolant System Integrity — A structurally sound surge tank hose maintains consistent coolant pressure across the circuit; a cracked or collapsed hose can allow air ingestion or coolant loss, leading to overheating under load.
- Verified Part Number — Sourced directly under Multiquip part number M5317200003, eliminating guesswork when cross-referencing against service manuals or parts diagrams for this generator series.
The surge tank hose connects the engine's coolant overflow or deaeration surge tank to the main cooling circuit, allowing trapped air and excess coolant to be managed as the system heats and cools through operating cycles. By venting air out of the cooling loop and returning recovered coolant back into the system, it helps maintain stable coolant levels and consistent operating temperatures. When this hose deteriorates — through cracking, softening, or connection fatigue — coolant can escape or air can enter the circuit, both of which compromise the engine's ability to shed heat during continuous generator operation.
