Volvo Penta KAD300 Cooling System Plug Late Type 3582636

Volvo Penta 3582636 is a genuine OEM plug used in select Volvo Penta cooling-system applications. Current dealer schematic references place this part directly in the KAD300-A cooling system diagram, where it appears as plug object key 11 alongside the oil cooler, hose nipples, hoses, and clamps in the cooler and heat-exchanger circuit.

Key Features

• Genuine Volvo Penta OEM part number 3582636.
• Identified in current Volvo Penta schematic references as Plug, object key 11.
• Strongest application reference places it in KAD300-A / Cooling System.
• Current catalog references also describe it as a late type plug.
• One current parts source notes it is included in aftercooler kit 877389.

Engine Compatibility

The strongest supportable fitment for 3582636 is Volvo Penta KAD300-A, based on current schematic references that place it in the cooling-system layout for that engine family. Additional catalog evidence tying it to aftercooler kit 877389 suggests it is associated with cooling and aftercooler service on related Volvo Penta diesel applications, but the safest compatibility statement is still to match this plug to the exact Volvo Penta cooling-system schematic and serial-number-based application before ordering.

Serial Number Fitment Notice

Match Volvo Penta part number 3582636 to your engine serial number and the correct cooling-system diagram before ordering. Small cooling-system plugs can vary by engine version, aftercooler setup, and production break, even when the surrounding hoses and cooler layout look very similar.

When This Part Needs Replacement

This plug should be replaced when it is damaged, corroded, leaking, or disturbed during cooling-system or aftercooler service. It is also worth replacing when adjacent cooler or hose components are already apart, especially if the original plug shows wear or sealing-surface damage. This service guidance is an inference based on the part’s placement in the KAD300-A cooling and cooler circuit.

Installation Notes

Confirm the exact application in the correct Volvo Penta schematic before installation, and compare the removed part carefully against the replacement plug. Inspect the mating port and nearby cooler, hose, and nipple connections before reassembly. In cooling-system assemblies, exact schematic match matters more than a quick visual comparison. This guidance is grounded in the part’s schematic placement within the KAD300-A cooler and heat-exchanger layout.

Alternate/Superseded Part Numbers

Current reviewed sources continue to list 3582636 as the active Volvo Penta OEM number. Current parts references also note that it is included in aftercooler kit 877389, which is a useful related service reference when checking the correct application.

Parts Desk Insight

With small cooling-system plugs like this, the easy mistake is focusing only on thread or size. Matching the exact cooler and aftercooler diagram first usually saves time, especially when nearby plugs in the same assembly can look interchangeable once removed.
