## ⚠️ Common Signs of Failure

-   Engine temperature rises under load or at low vehicle speed
-   Fan remains fully engaged, causing excessive noise and power loss
-   Fan freewheels when hot or has little resistance
-   Silicone-fluid leakage or oily staining around the hub
-   Bearing play, wobble, vibration or contact between the fan and shroud

## 🛠️ Service Notes

-   Inspect fan blades, hub bearings, belt tension and radiator airflow before condemning the clutch
