🔧 Product Description

Genuine Volvo Penta plug from the Engine group, weighing 0.025 kg and listed for 7 applications across the TMD, TAMD and MD series. It supersedes 859816, which was catalogued earlier as a connector — so paperwork listing 859816 as a connector now resolves to this plug.

🔌 Function

Closes off a drilling or port in the engine so the passage behind it stays sealed and holds pressure.

⚠️ Common Signs of Failure

• Weeping or a damp trace around the plug
• Sealing face pitted or the seat corroded
• Plug loose, backed out or missing
• Pressure lost from the passage the plug closes

🛠️ Service Notes

• Because 859816 was listed as a connector, an old parts list may describe this position differently from what arrives — check the fitting against the engine before condemning the supply
• Clean the seat and fit a new plug rather than reusing the old one
