The Multiquip M3310503703 Lower Radiator Hose is a genuine OEM component designed for DCA150SSI, DCA150SSIU, DCA180SSI, and DCA180SSIU ultra-silent diesel generators. Sourced directly from Multiquip, this hose matches the original routing, diameter, and material specification of the factory-installed part. It confirms compatibility with the DCA150SSI and DCA180SSI generator families, giving you confidence in fit before the part ever arrives on site. DHS Equipment stocks Multiquip M3310503703 so you can get your generator back online without sourcing delays.
Key Features
- Genuine OEM Construction — Manufactured to the exact compound and wall thickness spec of the original hose, ensuring correct coolant flow and pressure retention in a diesel generator cooling circuit.
- Lower Circuit Fitment — Routes coolant from the radiator back to the engine block; seats directly onto the OEM lower hose connections with no trimming or adapting required.
- Confirmed Generator Compatibility — Direct fit for DCA150SSI, DCA150SSIU, DCA180SSI, and DCA180SSIU ultra-silent generator models.
- Cooling System Integrity — A deteriorating lower hose is a leading cause of coolant loss and overheating; replacing it promptly protects the engine from thermal damage during extended generator run cycles.
- Fuel and Coolant Safety — Correct hose material resists the internal pressure spikes common in diesel cooling systems, reducing the risk of burst hose failures that can take a generator offline unexpectedly.
The lower radiator hose carries cooled coolant from the bottom of the radiator back to the engine's water pump, completing the continuous loop that keeps the diesel engine from overheating. In ultra-silent generator sets like the DCA150SSI and DCA180SSI series, which often run for extended periods under sustained load, this hose is under constant thermal and pressure cycling. Over time, the rubber compounds can soften, crack, or collapse internally, restricting coolant flow and leading to elevated engine temperatures. Replacing a worn lower radiator hose with the correct OEM part, Multiquip M3310503703, restores full cooling capacity and protects the engine from heat-related wear.
