Volvo Penta 3586514 is a genuine OEM O-ring used in select Volvo Penta cooling-system service applications. Current dealer and distributor references consistently identify it as an original Volvo Penta sealing ring, with strong support around D1 and D2 diesel thermostat-related service and additional catalog appearances in certain larger-engine parts references, so fitment should be matched by engine model and serial number rather than appearance alone.
Key Features
- Genuine Volvo Penta OEM part number 3586514.
- O-ring sealing component for select cooling-system and thermostat-related applications.
- Commonly referenced for Volvo Penta D1 and D2 marine diesel service.
- Best matched by engine model and serial number for accurate fitment.
Engine Compatibility
Strong supportable references link 3586514 to Volvo Penta D1-13, D1-20, D1-30, D2-40, D2-55, D2-60, and D2-75 applications, especially around thermostat or thermostat-housing service. Additional dealer catalog references also show this O-ring appearing across broader Volvo Penta engine families, which is why exact fitment should be confirmed against the engine serial number and parts breakdown before ordering.
Serial Number Fitment Notice
Volvo Penta parts usage can vary by engine version, production break, and component housing. Match part number 3586514 to your engine serial number or existing parts schematic before ordering to confirm the correct sealing location and application.
When This Part Needs Replacement
Replace this O-ring anytime the related thermostat housing or cooling-system sealing point is opened, or when the original seal shows flattening, hardening, cracking, coolant seepage, or loss of elasticity. Replacing a low-cost seal during service is usually the safer choice than reusing an aged one.
Installation Notes
Install only on a clean sealing surface and compare the old seal carefully against the new OEM O-ring before assembly. Light lubrication with the appropriate engine-safe fluid can help prevent pinching during installation. Avoid stretching, twisting, or reusing a compressed old seal when servicing thermostat or cooling-system components.
Alternate/Superseded Part Numbers
Current references reviewed identify 3586514 as the active Volvo Penta OEM number. Related service references may show it alongside other cooling-system seal numbers such as 3581070 and 3583830 within certain gasket or heat-exchanger service kits, but those are separate components rather than direct replacements.
Parts Desk Insight
With O-rings like this, the easy mistake is matching by size alone. On Volvo Penta cooling parts, the safer move is always to verify by serial number and housing application, especially when the same reference can appear in more than one engine family.
