The Multiquip M2310500603 is a genuine OEM Lower Radiator Hose designed for the DCA70SSJU, DCA70SSJU2, DCA70SSJU-GEER, DCA-70SSJU3, DCA85SSJU, and DCA70SSIU2-FEMA super-silent diesel generator series. As a direct OEM replacement, this hose is manufactured to the exact dimensions and material specifications of the original component, ensuring a correct, leak-free connection between the engine and radiator. Sourced directly through Multiquip's authorized parts network, it is the same component installed at the factory — eliminating the guesswork of aftermarket alternatives. DHS Equipment stocks this part for these generator families, so you can get the right hose and get your machine back online fast.
Key Features
- OEM-Grade Coolant Hose Construction — Manufactured to the same reinforced rubber compound and wall thickness specifications as the original, resisting heat cycling, pressure fluctuations, and coolant degradation over extended run times.
- Drop-In Fitment for Lower Coolant Circuit — Engineered to the exact length, diameter, and bend geometry of the factory lower hose, connecting directly to the original lower radiator port and engine inlet without trimming or adapting.
- Confirmed Fitment Across DCA Super-Silent Models — Verified for DCA70SSJU, DCA70SSJU2, DCA70SSJU-GEER, DCA-70SSJU3, DCA85SSJU, and DCA70SSIU2-FEMA generator variants.
- Sustains Proper Coolant Flow — A sound lower radiator hose maintains the continuous coolant circulation that keeps diesel generator engines operating within safe temperature ranges during sustained load; a cracked or collapsed hose can cause rapid overheating and engine damage.
- Cooling System Integrity — Replacing a deteriorated lower hose before it fails prevents coolant loss and overheating events that can result in unplanned shutdowns during critical power generation applications.
The lower radiator hose carries coolant from the bottom of the radiator back to the engine water pump, completing the cooling circuit that regulates engine temperature during operation. Because it handles the cooled return flow at lower pressure, it is also subject to collapse under suction from the water pump if the hose wall weakens with age — restricting flow just as critically as an external leak would. Inspecting and replacing this hose at the first sign of softness, cracking, or swelling is an essential part of cooling system maintenance on any diesel-powered generator.
