Volvo Penta Sealing Ring 3582673

Volvo Penta 3582673 is a genuine OEM sealing ring used as the mechanical seal for the circulating / coolant pump on Volvo Penta D4 and D6 diesel engines. Current Volvo-linked parts references list it as Sealing Ring, while current distributor and marine-parts listings identify the same SKU as the mechanical seal for the Volvo Penta D4/D6 circulating pump.

Key Features

• Genuine Volvo Penta OEM part number 3582673.
• Used as the mechanical seal in Volvo Penta D4/D6 circulating pump service.
• Shown in Volvo-linked cooling-system parts layouts with related pump components including shaft 3582671, gasket 3818912, and pulley 3582674.

Engine Compatibility

The strongest supportable fitment for 3582673 is Volvo Penta D4 and D6 diesel engines in the circulating / coolant pump service area. Current Volvo-linked parts references place it in the D6-280A-A cooling system diagram, and current marine-parts listings describe it generally for Volvo Penta D4/D6 circulating pump applications.

Serial Number Fitment Notice

Verify fitment by exact engine serial number and the correct Volvo Penta cooling system / circulating pump parts diagram before ordering. With 3582673, the important match is the exact coolant-pump service application, because this seal is tied to a specific pump assembly rather than being a general-purpose engine seal.

When This Part Needs Replacement

This sealing ring is typically replaced during circulating pump repair, when the pump is leaking, or when the pump is already apart for shaft, gasket, or bearing-related service. That guidance follows its documented role as the mechanical seal in the D4/D6 circulating pump assembly.

Installation Notes

Install 3582673 only after confirming the correct Volvo Penta pump breakdown for the engine being serviced. Current references show it working with related parts such as shaft 3582671 and gasket 3818912, so it is best replaced in the correct pump repair sequence rather than as an isolated seal swap without confirming the rest of the pump condition.

Alternate/Superseded Part Numbers

Current sources reviewed show 3582673 as the active Volvo Penta OEM reference. Related repair references connected to the same pump service area include 3588474 and the related pump-shaft / gasket parts used in the same repair.

Parts Desk Insight

For this part, the important match is the circulating pump application, not just the words sealing ring. Checking the D4/D6 pump diagram first usually helps avoid ordering a seal for the wrong repair area.
