## ⚠️ Common Signs of Failure

-   Coolant weeping or dripping from under the banjo connection
-   Coolant level falling with white or pink crusting at the joint
-   The screw found slack, or leaking again shortly after being tightened
-   Sealing washers found flattened, or the sealing faces scored on strip-down
-   Cross-drilling blocked with debris or corrosion, so coolant flow is restricted

## 🛠️ Service Notes
