## ⚙️ Key Features

-   Supersedes 819689
-   0.014 kg
-   4 recorded applications on the MD and AQD series
-   Cooling System group

## 🔌 Function

Seals a cooling system joint so the circuit holds pressure and coolant stays inside it.

## ⚠️ Common Signs of Failure

-   Coolant weeping at the joint once the system is hot and pressurised
-   Crusty white or coloured deposit dried around the flange
-   Header tank dropping with nothing visible when cold
-   Gasket swollen, softened or crushed thin on removal
-   Pitting and corrosion on the face beneath the old gasket

## 🛠️ Service Notes

-   Clean corrosion off the flange before fitting — pitted metal under a gasket is the usual reason a new one weeps immediately
-   Pressure-test the system rather than waiting for a sea trial to find the leak
