## 🔌 Function

Terminates the engine coolant-temperature sensor circuit at the harness, holding the terminals in position and sealing the joint against heat and coolant.

## ⚠️ Common Signs of Failure

-   Temperature gauge or reading jumping, or sitting at an implausible value
-   Cold-start behaviour poor, or a fan running when it should not
-   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

-   Confirm the reading with a gauge or reader before condemning anything - the sensor, the connector and the wiring all give the same symptom
-   Three kits in this family are published at 0.007 kg, so weight is no guide - order by the circuit named against the number
