## ⚙️ Key Features

-   7.4 GL only
-   1.644 kg
-   Supersedes 3851181
-   287 applications across V and DPX

## 🔌 Function

Houses the thermostat and directs coolant either back around the engine or on to the heat exchanger as the thermostat opens.

## ⚠️ Common Signs of Failure

-   Coolant weeping from the housing or its gasket face
-   Engine slow to warm up, or running hot
-   Temperature reading swinging as the thermostat hunts
-   Corrosion or scale pitting the sealing face
-   Cracks around the bolt holes or the outlet neck

## 🛠️ Service Notes

-   The listing restricts this housing to the 7.4 GL only, which sits oddly against a broad application list, so confirm the engine designation before ordering
-   Fit a new thermostat, gasket and seal with the housing
-   Clean the mating face carefully, as a pitted face will not seal against a new gasket
