Serial Number Fitment Notice
The critical distinction in this part family: 3584168 is the D6 exhaust hose. The visually similar 3584167 is the D4 version. Both occupy the same position in the DPH / DPR exhaust-pipe assembly but are engine-specific and cannot be swapped. Locate your engine ID plate on the block or valve cover and confirm the model begins with D6 before ordering.
What This Part Does
This hose routes exhaust gases and cooling-water discharge away from the D6 engine through the exhaust-pipe and cooling-water pipe assembly on DPH, DPR, and DPI sterndrive installations. Maintaining the correct OEM hose preserves the intended exhaust routing, flow geometry, and sealing integrity in the drive assembly.
When to Replace
- Hose shows cracking, hardening, swelling, or heat discolouration
- Evidence of exhaust or cooling-water leakage at either connection
- Internal deterioration or wall collapse detected during inspection
- Contamination from oil or exhaust byproducts
- During scheduled exhaust-system service or any sterndrive removal that exposes this assembly
Service Interval
Inspect this hose at every scheduled maintenance interval and whenever the sterndrive or exhaust assembly is opened for service. Replace immediately if cracking, swelling, or leakage is found. Inspect the hose clamp (3817486) and adjacent sealing components at every hose replacement.
Installation Notes
Before installing the new hose, inspect the associated exhaust pipe (40005584), hose clamp (3817486), and the nearby O-ring 969415. Ensure the hose is fully seated at both connections, confirm orientation matches the Volvo Penta parts diagram, and tighten all clamps to specified torque before returning to service.
Technical FAQ
Q: What is the difference between 3584168 and 3584167?
3584168 is the exhaust hose for D6 engines. 3584167 is the D4 version. Both sit in the same DPH / DPR exhaust assembly and the part numbers look nearly identical — but they are engine-specific. Confirm your engine begins with D6 before ordering this listing.
Q: Does this hose work with both DPH and DPR sterndrives?
Yes, for D6 engines. Confirmed applications include DPH-A, DPH-B, DPR-A, and DPR-B paired with compatible D6 models. Verify against your Volvo Penta parts diagram before ordering.
Q: Should I replace the hose clamp at the same time?
Yes. Inspect clamp 3817486 whenever the hose is replaced. Corroded or deformed clamps can prevent proper seating of the new hose and lead to leaks. Replace if there is any sign of corrosion or damage.
Q: Can I reuse the O-ring during reinstallation?
Inspect it carefully. If O-ring 969415 shows any flattening, cracking, or deformation, replace it. Reusing a compromised O-ring is a common cause of post-service leaks in this assembly.
Related Parts — Commonly Serviced Together
- Volvo Penta Exhaust Hose 3584167 – D4 DPH / DPR / DPI — D4 counterpart; same assembly position, different engine
- Volvo Penta O-Ring 969415 — adjacent O-ring in the exhaust-pipe assembly; inspect and replace during same service event
Parts Desk Insights
Best use case: Scheduled D6 exhaust-system service, or any sterndrive removal on a DPH or DPR installation that exposes the exhaust-pipe assembly. Since the hose is accessed during the same disassembly as the clamp and nearby O-ring, replacing all three at once avoids reopening the assembly for a secondary leak.
Common issue: The single most common ordering error with this part is confusing 3584168 (D6) with 3584167 (D4). The part numbers differ by one digit and the hoses look similar in photos. Always confirm the engine designation is D6 — not D4 — before completing the order.
