About This Part
Genuine Volvo Penta 24219064 is the current OEM seawater pump assembly for selected Volvo Penta D6 marine diesel engines. It draws raw water through the engine’s cooling circuit and supplies the heat exchanger with the flow needed to remove engine heat — a critical function in any raw-water or closed-loop cooling setup. This pump supersedes earlier D6 pumps 22901578 and 21419376, all of which belong to the same later D6 seawater-pump family. Earlier D6 engines can use a different pump family (21380890 / 3589907), so confirming the engine’s full model, suffix, and serial number is essential before ordering.

When to Replace
Replace this seawater pump when inspection or diagnosis reveals any of the following:
- Persistent raw-water leakage from the pump body or shaft seal
- Damaged shaft or bearing assembly
- Excessive shaft play detected during inspection
- Severe internal housing or wear-plate damage
- Repeated impeller failure caused by internal pump wear
- Reduced raw-water flow that cannot be corrected with impeller service alone
- Corrosion or structural damage to the pump housing
- Engine overheating with no other identified cause
A worn seawater pump reduces cooling-system flow and can contribute to elevated engine operating temperature. This pump is also commonly replaced as part of a full cooling-system overhaul when the housing or shaft seal shows significant wear.
Installation Notes
Inspect the impeller, wear plate, cover, seals, O-rings, pump-drive components, hoses, and clamps during replacement. Verify all hose connections and pump orientation before priming the raw-water circuit. After installation, confirm strong seawater discharge and check the pump and all hose connections carefully for leakage before returning the engine to service.
Technical FAQ
Does this pump include the impeller? This is the complete pump assembly. Confirm with your parts reference whether the impeller is included or serviced separately on your specific engine variant and suffix.
Can I use this pump if my engine shows 21419376 in the parts manual? In many D6 E- and F-series applications, 24219064 is the current superseding part for 21419376 — but the changeover is serial-number dependent. Verify the serial break applies to your engine before ordering.
What causes premature pump failure? Running the engine without water flow, debris ingestion through the raw-water intake, and infrequent impeller service are the most common causes. Inspect the impeller at each cooling system service interval.

Parts Desk Insight
The most common issue with D6 seawater pump orders is assuming “fits D6” is sufficient. There are two major seawater pump families within the D6 range, and the wrong one will not fit. For engines with a service history showing 21419376 or 22901578, 24219064 is the current replacement — but the serial number break still needs to be confirmed before ordering. The most common reason for premature pump failure is a dry-run event during winterization or launch when the raw-water intake is not yet submerged. If the engine was run without water flow for any period, inspect the impeller and pump internals before the next season rather than waiting for a leak to develop.
