## ⚙️ Key Features

-   4.357 kg
-   37 applications across TD, TWD, TID and TAD engines
-   Cooling System group casting

## 🔌 Function

Houses the thermostat and directs coolant either back through the bypass or out to the cooler as the engine warms.

## ⚠️ Common Signs of Failure

-   Coolant seeping from the housing joint or from a porous casting
-   Engine slow to warm, or overheating with a thermostat that tests good
-   Corrosion pitting and scale build-up inside the bores
-   Stripped or pulled fixing threads in the casting
-   Thermostat seat eroded so the valve no longer seals

## 🛠️ Service Notes

-   Housing 470548 at 4.146 kg is the TMD and TAMD version - the two are close in weight, so order by engine series rather than by size
-   Renew the housing gasket and the thermostat at the same time, and check the mating face on the head for flatness
