Volvo Penta 855582 is a genuine sealing ring used in the cooling-system / heat-exchanger and water-filter installation group on older Volvo Penta gasoline engines. Current Volvo Penta references identify it simply as a sealing ring, while current schematic-based sources place it in the heat exchanger and water filter installation assembly used on AQ131, AQ151, AQ171, 230, 250, and 251-series applications. Current references show it as a small individual sealing component used alongside nearby parts such as connector 855791 and connection pipe 856083/856084 in that cooling-system layout.
Key Features
- Genuine Volvo Penta part number 855582.
- Identified by current references as a sealing ring in the cooling-system group.
- Used in heat exchanger and water filter installation diagrams on older Volvo Penta gasoline engines.
- Sold as an individual service part rather than a complete kit.
Engine Compatibility
Current references show Volvo Penta 855582 associated with AQ131A, AQ131B, AQ131C, AQ131D, AQ151A, AQ151B, AQ151C, AQ171A, AQ171C, 230A, 230B, 250A, 250B, and 251A applications. The strongest current application references place it specifically in the heat exchanger and water filter installation assemblies for AQ131, AQ151, and AQ171 families. Fitment should be confirmed by exact engine model, serial number, and cooling-system layout before ordering.
Serial Number Fitment Notice
Cooling-system seals can vary by engine family, water-filter housing, heat-exchanger arrangement, and production range. Confirm Volvo Penta 855582 by engine serial number and by matching the installed sealing-ring location in the heat exchanger / water filter assembly before ordering. Volvo Penta's official parts shop continues to list 855582 as an active genuine sealing ring.
When This Part Needs Replacement
Replace this sealing ring whenever the related cooling-system component is removed, or when there are signs of seepage, flattening, hardening, swelling, cracking, or loss of sealing tension. On older Volvo Penta heat exchanger and water-filter assemblies, small seals like this are inexpensive but important service items, especially during connector, pipe, strainer, or housing work. This service guidance follows from the part's current placement in the heat exchanger / water filter installation group.
Installation Notes
Install the new sealing ring on clean mating surfaces and confirm it matches the existing groove, housing, and connector arrangement before assembly. Because current references place 855582 in assemblies with connection pipe 856083/856084 and connector 855791, it is a good idea to inspect the nearby plastic and metal cooling-system parts for wear, distortion, or corrosion during installation. Light lubrication with a cooling-system-safe assembly aid can help prevent pinching during reassembly where appropriate for the application.
Alternate/Superseded Part Numbers
Current reviewed references consistently identify 855582 as the active Volvo Penta part number for this sealing ring. No confirmed superseded Volvo Penta number is clearly shown in the reviewed references.
Parts Desk Insight
For older Volvo Penta cooling-system parts, the word “sealing ring” can sound generic, but the real checkpoint is the exact assembly location. In this case, current references repeatedly place 855582 in the heat exchanger / water filter installation group, which makes serial-number confirmation and visual comparison to the existing seal the best way to avoid ordering the wrong small part.
