## 🔌 Function

Terminates the coolant or water-level sensor circuit at the harness, holding the terminals in position and sealing the joint against water and heat.

## ⚠️ Common Signs of Failure

-   Coolant or level warning appearing and clearing for no apparent reason
-   Sensor reading dropping out when the loom is moved
-   Connector body cracked, or the latch broken so it will not lock
-   Green corrosion or water tracks found on the pins when opened
-   Terminals found corroded or backed out on strip-down

## 🛠️ Service Notes

-   A coolant or level warning that comes and goes is more often the connector or its earth than the sensor - test before replacing either
-   This connector sits in a wet, hot area, so refit the seal and boot exactly as they came off
