🔌 Function

Closes a drilling or aperture in the cooling circuit, sealing it against coolant pressure and providing the seat that the anode screws into where one is fitted.

⚠️ Common Signs of Failure

• Plug thread corroded, seized or wasted thin
• Head rounded off by previous attempts to remove it
• Plug found badly eaten away when the anode is serviced
• Coolant loss with no other leak visible

🛠️ Service Notes

• Anode 838929 is listed for the same 22116247, so inspect and renew both together
