## ⚙️ Key Features

-   Engine group plug
-   0.032 kg
-   Supersedes 964089
-   Listed for 33 applications across the D series

## 🔌 Function

Closes off a machined port or gallery in the engine, sealing it against pressure so the fluid inside stays in its intended path.

## ⚠️ Common Signs of Failure

-   Weep or drip from the plug rather than from a gasket
-   Oil or coolant staining around a blanked port
-   Plug head socket or hex rounded off from over-tightening
-   Threads or sealing washer face damaged
-   Plug found loose on inspection

## 🛠️ Service Notes

-   Use a new sealing washer if the original had one, and clean the threads in the casting before fitting
-   Tighten to seat the seal and no more - over-tightening is what rounds the head and distorts the sealing face
