Technical FAQ
- How do I confirm this fits my engine? Locate your engine model and serial number on the engine label, then verify 3863104 appears in the correct parts diagram position for your cooling circuit.
- Is this a genuine Volvo Penta part? Yes — this is a genuine OEM component, not an aftermarket substitute.
- Can I use an aftermarket water inlet instead? OEM is recommended for cooling-system components where geometry and material compatibility directly affect sealing and flow performance.
- What if my part number has been superseded? Volvo Penta periodically updates part numbers. If 3863104 has been superseded, the current number will appear in the parts catalog — confirm before ordering.
Parts Desk Insights
Best use case: Direct OEM replacement for the raw-water inlet position where 3863104 is specified in the Volvo Penta parts diagram for the engine and cooling configuration.
Most common mistake: Ordering by part name alone without verifying by engine model and serial number. Water inlet geometry and connection style can vary between engine families and production ranges — serial-number verification is the only reliable confirmation.
Fitment guidance: Locate your engine ID plate, note the model and serial number, and cross-reference 3863104 in the correct parts catalog section before ordering. If your serial range falls on a production break, confirm whether a superseded number applies.
