🔧 Product Description

Genuine Volvo Penta Engine Expansion / Core Plug - Part Number: 20884347

🔌 Function

The plug is driven or pressed into the prepared bore, where its interference fit creates radial sealing pressure. It closes a manufacturing or service opening so the internal fluid circuit remains contained.

Common signs of failure:

• Coolant or oil seepage around the plug edge

• Corrosion perforates the plug

• Plug moves outward because the bore is damaged

• Incorrect installation distorts or splits the plug

• Leak recurs due to casting corrosion behind the plug
