The Multiquip M1311501403 Radiator Hose Lower is a genuine OEM component designed for DCA40SSKU4F2 ultra-silent and super-silent series diesel generators. Sourced directly from Multiquip, this hose is manufactured to the exact dimensions and material spec required for proper coolant routing on this generator family. Verified fitment against the DCA40SSKU4F2 means no guesswork when ordering the correct replacement. DHS Equipment stocks this part ready to ship so your generator gets back online fast.
Key Features
- OEM-Grade Hose Construction — Manufactured to the exact inner diameter, wall thickness, and bend profile specified for the DCA40SSKU4F2 cooling circuit, ensuring a leak-free seal at both connection points.
- Direct-Fit Lower Coolant Routing — Connects the lower radiator outlet to the engine inlet with no trimming or adapter fittings required; installs exactly as the original hose did.
- Confirmed Fitment for DCA40SSKU4F2 — Validated for Multiquip DCA40SSKU4F2 Tier 4 super-silent diesel generators operating at 60 Hz.
- Sustained Coolant Flow at Operating Temperature — A properly functioning lower radiator hose maintains full coolant volume between the radiator and engine block; a collapsed or cracked hose restricts flow and leads to engine overheating under load.
- Pressure and Heat Resistance — Built to withstand the thermal cycling and coolant system pressures typical of continuous-duty generator operation, resisting softening, cracking, and interior collapse over time.
The lower radiator hose carries cooled coolant from the bottom of the radiator back to the engine water pump, completing the closed-loop cooling circuit that keeps engine temperature within the safe operating range. On a generator like the DCA40SSKU4F2 running under sustained load, consistent coolant flow through this hose is critical — a hose that has softened, collapsed internally, or developed a leak will starve the engine of cooling and trigger thermal shutdown or cause engine damage. Replacing a worn lower radiator hose at the first sign of cracking, swelling, or seepage is one of the most cost-effective preventive maintenance steps on any diesel-powered generator.
