What This Part Does
The 3859083 is a retaining component in the Volvo Penta lubricating system, specifically within the oil cooler housing assembly on selected 8.1L gasoline engines.

Fitment spans multiple 8.1Gi, 8.1GiE, 8.1GiI, and 8.1GXiI variants. Confirm against your engine serial number and oil-system parts diagram before ordering — oil-system layouts can vary between engine versions within the same displacement family.
Serial Number Fitment Notice
Use your engine serial number to locate the correct Volvo Penta lubricating-system diagram and verify that 3859083 is shown in the oil cooler housing group before ordering. This is the most reliable confirmation method across 8.1L engine variants.
When to Replace
- Retainer is damaged, bent, cracked, or corroded
- Part was lost or damaged during oil cooler or housing service
- Retainer no longer secures the associated oil-system component correctly
- Oil cooler assembly is being rebuilt or serviced and original is non-serviceable
Installation Notes
While the oil cooler housing assembly is apart, inspect the O-ring (3852470), connector (3852097), and all sealing surfaces. Replace the O-ring and any other worn components at the same time to avoid re-opening the assembly. Install the retainer in the exact orientation shown in the applicable Volvo Penta lubricating-system diagram. Follow Volvo Penta torque specifications for all oil-system fasteners before returning the engine to service.
Technical FAQ
Q: Does 3859083 fit all Volvo Penta 8.1L engines?
A: It fits multiple 8.1Gi, 8.1GiE, 8.1GiI, and 8.1GXiI applications, but not necessarily every 8.1L variant. Confirm using your engine serial number and the Volvo Penta parts diagram for your specific engine.
Q: Is there a superseding part number for 3859083?
A: No confirmed superseding number has been identified. Order directly as 3859083.
Q: Should I replace the O-ring when replacing this retainer?
A: Yes, it is good practice. The 3852470 O-ring is part of the same oil cooler housing assembly. Replacing it while the housing is already apart avoids a repeat service call for an oil-side leak.

Parts Desk Insights
This retainer shows up most often when a customer is servicing the oil cooler on an 8.1L engine and finds the original is bent or missing. The part is inexpensive relative to the labor of re-opening the oil-system housing, so it is worth ordering fresh any time the assembly is being disturbed. Match by serial number — the 8.1L family spans a range of Gi/GiE/GiI variants and the oil-system diagram is the fastest way to confirm you have the right piece before tearing into the job.
