## 🔌 Function

The cooler transfers heat from transmission oil to the engine raw-water circuit, maintaining oil viscosity and protecting clutches, bearings and seals.

## ⚠️ Common Signs of Failure

-   Transmission oil temperature is excessive
-   Cooler leaks oil or seawater
-   Oil becomes contaminated with water
-   Hose or fittings are corroded

## 🛠️ Service Notes

-   If only the heat exchanger has failed and the hoses and bracket are sound, cooler element 21112814 at 1.286 kg is the part on its own
-   Pressure-test both the oil and water sides before commissioning the circuit
