Serial Number Fitment Notice
Fitment should always be confirmed by engine serial number before ordering. Volvo Penta’s official guidance is to identify the exact engine, shield, or drive when selecting replacement parts.

When This Part Needs Replacement
Replace this gasket when:

• the water circulation pump is being removed or serviced
• the original gasket is brittle, flattened, or damaged
• coolant seepage is visible at the pump joint
• the pump assembly has been opened and needs a fresh gasket for reassembly

Installation Notes

• Confirm fitment by serial number first.
• Match the gasket to the exact circulation-pump sealing surface before installation.
• Clean both mating faces fully before reassembly.
• Replace the old gasket during service instead of reusing a compressed seal.

Replaces / Cross Reference Numbers

• 859027
• Current cross-reference listings also show 1542229 as a related/replaced reference.

Parts Desk Insight
This is a small gasket, but it sits in a cooling-system joint where reopening the same pump costs far more than the gasket itself. On older Volvo Penta diesel circulation-pump service, replacing the gasket during reassembly is usually the cleaner move for a more reliable seal.
