## ⚙️ Key Features

-   30 mm diameter
-   0.009 kg
-   55 applications
-   TAMD, AD, D, TMD, TD and MD series

## 🔌 Function

Seals a cast drilling in the block or head, expanding into the bore as it is driven home.

## ⚠️ Common Signs of Failure

-   Coolant weeping or a crusted stain around the plug
-   Plug dished, rusted through or perforated
-   Plug pushed out or standing proud of the casting
-   Corrosion pitting in the plug bore

## 🛠️ Service Notes

-   Order by the 30 mm diameter - expansion plugs are separated by bore size
-   Clean the bore back to bare metal and use a sealant on the seat; a rusted seat is why the replacement leaks
-   Drive the plug squarely with a drift the same size as its face, not on the edge
