Volvo Penta 855791 is a genuine connector used in the cooling-system / seawater-filter group on older Volvo Penta gasoline applications. Current Volvo Penta parts references identify it simply as a connector, while multiple current cross-references show it as the active replacement for earlier part number 831931. Current references also place this part in seawater filter and heat exchanger / water filter installation diagrams, which makes it best described as a cooling-system connector rather than a general electrical fitting.
Key Features
- Genuine Volvo Penta OEM part number 855791.
- Current cross-references show 855791 replacing earlier part number 831931.
- Listed in current schematic references under seawater filter and heat exchanger / water filter installation components.
- Small OEM service part, with current seller specs commonly showing about 0.05 kg shipping weight.
Engine Compatibility
Current reviewed references most clearly tie Volvo Penta 855791 to the seawater filter / heat exchanger water-filter connector group rather than publishing a broad official engine list. Some current market references associate it with older AQ131 / AQ151 applications, but the strongest confirmed application signal in the reviewed sources is the seawater-filter diagram placement and the 831931-to-855791 replacement relationship. Fitment should be confirmed by engine serial number and cooling-system layout before ordering.
Serial Number Fitment Notice
Cooling-system connectors can vary by engine family, seawater-filter arrangement, and heat-exchanger plumbing layout. Confirm Volvo Penta 855791 by engine serial number and by matching the installed connector shape, size, and hose / pipe routing before ordering. Volvo Penta continues to list 855791 as a genuine connector part number.
When This Part Needs Replacement
Replace this connector when the original part is cracked, corroded, leaking, damaged at the sealing surfaces, or removed during cooling-system service and found unserviceable. On older Volvo Penta cooling systems, small connector pieces around the seawater filter and heat exchanger can become problem points when chasing coolant or raw-water seepage. This service guidance follows from the part's current placement in seawater-filter and heat-exchanger installation references.
Installation Notes
Match the replacement directly to the existing connector and confirm the surrounding seawater-filter / heat-exchanger plumbing is correct before installation. Inspect adjoining hoses, pipe ends, clamps, and sealing points so the new connector is fitted into a sound assembly. Because current public references identify the part more clearly than they publish a full factory fitment list, visual comparison and serial-number confirmation are the safest installation checkpoints.
Alternate/Superseded Part Numbers
Current references show Volvo Penta 855791 as the active replacement for 831931. No additional confirmed newer supersession is clearly shown in the reviewed current references.
Parts Desk Insight
For older Volvo Penta cooling-system parts like 855791, the fastest way to get the right part is to match the exact plumbing location rather than the word “connector” alone. This part sits in a small but important part of the water-routing system, and the strongest buying checkpoints are its placement in the seawater-filter / heat-exchanger group and its replacement relationship to 831931.
