## ⚙️ Key Features

-   4.559 kg
-   61 applications across D, TMD, TAMD and MD engines
-   Coolant expansion tank

## 🔌 Function

Holds the coolant that expands as the engine warms, provides the filling point and the level reference, and lets air separate out of the system.

## ⚠️ Common Signs of Failure

-   Coolant level dropping steadily with staining down the tank
-   Coolant pushed out of the overflow when the engine is hot
-   Tank cracked, crazed or bulging
-   Air repeatedly gathering in the system
-   Filler neck or cap seat corroded so the cap will not seal

## 🛠️ Service Notes

-   Test the pressure cap at the same time - a weak cap pushes coolant out and gets blamed on the tank
-   Level indicator 3827766 belongs to the same part of the system and is worth checking while the tank is off
