Volvo Penta 3584168 – D6 Exhaust Hose
Part Number: 3584168
Brand: Volvo Penta
Official Product Type: Exhaust Hose (OEM)
Supersedes: No prior part number on record
Replaced By: No current supersession — 3584168 is the active OEM number
Engine Family: Volvo Penta D6 Marine Diesel
System: Exhaust and Cooling Water Discharge Assembly
Weight: 4.0 kg (8.8 lb) estimated
The Volvo Penta 3584168 is the genuine OEM exhaust hose for D6 marine diesel engines equipped with DPH and DPR sterndrives. It is installed in the exhaust pipe and cooling water pipe assembly, routing exhaust gases and cooling water discharge away from the engine. The counterpart hose for D4 engines in the same assembly is 3584167 — these two are not interchangeable.
Compatible Applications
Verify your engine model, drive model, and serial number before ordering.

Later D6 variants in DPH/DPR installations may also use this hose. Confirm against the Volvo Penta parts diagram for your exact engine and drive combination before ordering.
Serial Number Fitment Notice
Fitment must be confirmed by the exact D6 engine model, sterndrive model, and serial number. The 3584167 is the D4 exhaust hose used in the same DPH/DPR assembly — these two hoses serve different engines and are not interchangeable. Locate the engine identification plate on the block or valve cover and confirm your model and serial number before ordering.
Specifications
- Hose type: Exhaust and cooling water discharge hose
- System: Exhaust pipe and cooling water pipe assembly
- Application: D6 diesel marine engine with DPH / DPR sterndrive
- Weight: ~4.0 kg (8.8 lb) estimated
- Construction: Heat and water-resistant reinforced rubber
When to Replace
- Hose shows cracking, hardening, swelling, or heat damage
- Evidence of exhaust or cooling water leakage at hose connections
- Internal deterioration or collapsed hose wall
- Contamination from oil or exhaust byproducts
- During scheduled exhaust system service or sterndrive removal
Service Interval
Inspect the exhaust hose at every scheduled maintenance interval and during any sterndrive service that involves the exhaust assembly. Replace immediately if cracking, swelling, or leakage is found. Inspect adjoining clamps, the exhaust pipe, and sealing components at every hose replacement.
Installation Notes
Before installing, inspect the adjoining exhaust pipe (40005584), hose clamp (3817486), and nearby sealing components including the related O-ring. Ensure the hose is fully seated at both connections and all clamps are tightened to the specified torque before returning the engine to service. Confirm hose orientation matches the parts diagram — incorrect orientation can affect cooling water flow.

Technical FAQ
Q: What is the difference between 3584168 and 3584167?
A: 3584168 is the exhaust hose for D6 engines. 3584167 is the exhaust hose for D4 engines. Both are used in the same DPH/DPR exhaust assembly but are specific to their respective engine families. Ordering the wrong one is a common and costly mistake — confirm your engine designation before ordering.
Q: Does this hose work with both DPH and DPR sterndrives?
A: Yes, for D6 engines. Confirmed applications include DPH-A, DPH-B, DPR-A, and DPR-B paired with compatible D6 engine models. Verify against your parts diagram before ordering.
Q: Should I replace the hose clamp at the same time?
A: Yes. Inspect the clamp (3817486) whenever the hose is replaced. Old or corroded clamps can fail to seat the new hose correctly and lead to leaks. Replace if there is any sign of corrosion or deformation.
Q: Can I reuse the O-ring during reinstallation?
A: Inspect carefully. If the O-ring shows any flattening, cracking, or deformation, replace it. Reusing a compromised O-ring is a common cause of post-service leaks in this assembly.

Parts Desk Insights
The most common ordering error with this part is confusing 3584168 (D6) with 3584167 (D4). Both hoses sit in the same exhaust assembly on DPH/DPR drives, and the part numbers look similar — but they are engine-specific. Always confirm the engine designation is D6 before ordering this hose. If a customer is unsure, ask them to locate the engine ID plate and confirm the model begins with "D6".
When this hose is being replaced, it is good practice to inspect the hose clamp (3817486) and the related O-ring at the same time. Corrosion or deformation of these components during hose replacement is a common source of callbacks. Recommending them as a service set reduces repeat visits.
