What This Part Does
This is a genuine Volvo Penta OEM molded cooling hose designed for the seawater cooling circuit. It routes cooling water between the thermostat housing and the exhaust elbow area, supporting fuel pump cooling and overall seawater flow management. The molded profile is specific to the installation geometry — it is not a universal hose.
Compatible Applications
- Volvo Penta seawater-cooled engines using thermostat housing-to-exhaust elbow hose routing
- Fitment is engine- and serial-specific — always verify against your engine serial number and the correct Volvo Penta parts diagram before ordering
Serial Number Notice
Volvo Penta cooling hose routing and molded profiles vary by engine family, cooling layout, and production break. Confirm part number 21114718 against your exact engine serial number before ordering.
When to Replace
Replace this hose when it shows cracking, hardening, swelling, leaking, heat aging, or abrasion. It is also a practical replacement any time the surrounding thermostat housing or seawater assembly is apart and the original hose shows age or reduced flexibility.
Installation Notes
Inspect hose ends, clamps, mating necks, and nearby routing before reassembly. Follow the Volvo Penta service manual for your serial-numbered engine. Use the correct hose clamps for a leak-free seal.
Parts Desk Insights
The most common issue with molded Volvo Penta cooling hoses is assuming a close-fitting hose will work. The bend profile and routing angle matter as much as the diameter — a hose that looks similar can still be wrong for the connection angle or clearance around the thermostat housing, exhaust elbow, or pump area. Serial-number verification is the most reliable way to avoid installation issues and repeat labor.
