Volvo Penta 21114718 is a genuine OEM hose used in Volvo Penta cooling-system applications. Current parts references consistently identify 21114718 simply as "hose," and multiple catalog sources place it in a seawater / thermostat housing to exhaust elbow / fuel-pump cooling-water flow style application rather than as a universal hose.
Key Features
Genuine Volvo Penta OEM part number 21114718. Current seller and catalog references identify it as a molded cooling-system hose, with source descriptions connecting it to water flow that helps cool the fuel pump and to surrounding thermostat and exhaust-elbow plumbing. Available current references also list an approximate part mass of 0.30 lb and show diagram reference number 10 in the applicable exploded view.
Engine Compatibility
Current public references point to a seawater-system application associated with thermostat housing to exhaust elbows and related cooling-water routing. Because hose routing and molded profiles can vary by engine family, cooling layout, and production break, fitment should be treated as engine- and serial-specific rather than assumed across all Volvo Penta models.
Serial Number Fitment Notice
Always confirm 21114718 against the exact engine serial number and the correct Volvo Penta parts diagram before ordering. Volvo Penta's own parts resources direct customers to identify the exact engine, shield, or drive when locating the correct spare parts.
When This Part Needs Replacement
Replace this hose when the original hose is cracked, hardened, swollen, leaking, heat-aged, abraded, or removed during service and no longer suitable for reliable reuse. It is also a sensible replacement anytime the surrounding seawater or thermostat-housing assembly is apart and the original hose shows age or loss of flexibility. This service guidance is consistent with the cooling-system application described in current parts references.
Installation Notes
Install only in the correct matched Volvo Penta application. Inspect the hose ends, clamps, mating necks, and nearby routing points before reassembly, and follow the correct Volvo Penta service information for the serial-numbered engine. Volvo Penta's support resources provide model-specific manuals and technical information.
Alternate/Superseded Part Numbers
Current sources reviewed list this part under active Volvo Penta number 21114718. No confirmed superseded number was established in the sources reviewed here.
Parts Desk Insight
With molded Volvo Penta cooling hoses, the important check is not just diameter but the exact bend profile and installed routing. A hose that looks close can still be wrong for the connection angle or clearance around the thermostat housing, exhaust elbow, or pump area, so serial-number verification is the safest way to avoid installation issues and repeat labor. This is a practical inference supported by the current seawater-system and thermostat/exhaust routing references for 21114718.
