🔌 Function

Blanks off an unused port or protects an open connection in the cooling system so coolant cannot escape and dirt cannot enter.

⚠️ Common Signs of Failure

• Coolant weeping from a blanked port
• Coolant level dropping with no obvious drip when cold
• Plug found loose, split or missing
• Sealing face or thread found damaged
• Dirt found in a port where the plug had been lost

🛠️ Service Notes

• Fit a new plug rather than refitting a used one — a plug that has been driven or screwed out will not seal reliably a second time
• Clean the bore or threads out fully and check the sealing seat for corrosion pitting and damage; a pitted seat will keep weeping whatever plug is fitted
• Fit the plug squarely and to the depth or tightness given in the workshop manual for your engine, using only the sealant or thread compound specified for that joint
• Support the surrounding casting where you can and drive or tighten without distorting the plug, then pressure test or run the engine up and check the plug for weeping
