## ⚙️ Key Features

-   One-way sender for double instruments
-   40-120°C range
-   0.045 kg
-   72 published applications across six engine series

## 🔌 Function

Changes resistance with coolant temperature so the instrument shows the engine's running temperature.

## ⚠️ Common Signs of Failure

-   Gauge reading permanently cold, permanently hot or wandering
-   Gauge needle jumping with engine vibration
-   Coolant weeping around the sender thread
-   Terminal corroded or the connection loose
-   Reading disagrees with a hand-held check on the same engine

## 🛠️ Service Notes

-   Confirm whether the installation uses a one-way sender for double instruments before ordering, since senders of the same size can differ in the number of terminals
-   Sender 840345 is the alternative for the 827151 sender and the 833927 thermoswitch control, so establish which arrangement the engine carries
-   Seal the thread and top up coolant after fitting, then compare the gauge against a separate reading
