## ⚙️ Key Features

-   Coolant level sensor from the Cooling System group
-   0.016 kg
-   Listed for 30 D series engine applications
-   Rated 150 A

## 🔌 Function

Watches the coolant level in the expansion tank and signals the control system when it falls below the safe mark, so a leak is caught before the engine overheats.

## ⚠️ Common Signs of Failure

-   Low coolant warning showing with a full tank, or no warning when the level really is low
-   Warning that flickers with boat movement or engine vibration
-   Fault code logged against the coolant level circuit
-   Sensor body coated in scale or sludge on removal
-   Coolant weeping around the sensor seal

## 🛠️ Service Notes

-   Check the actual level and the sensor connector before condemning the sensor - a corroded pin gives the same symptom
-   Renew the sealing ring when the sensor is refitted
-   Top up and bleed the system afterwards so the reading settles
