## ⚙️ Key Features

-   0.47 kg
-   7 applications on the TWD series
-   Formed pipe, no bending needed on fitting

## 🔌 Function

Carries air trapped in the cooling circuit up to the expansion tank so the system can vent and fill completely without an air lock.

## ⚠️ Common Signs of Failure

-   Engine running hot despite a full coolant level
-   Coolant level in the tank rising and falling erratically
-   Air still trapped in the system after filling and bleeding
-   Coolant weeping or crusted deposits at the pipe unions
-   Pipe corroded thin, split or chafed where it is clipped

## 🛠️ Service Notes

-   Renew the union seals and refill and bleed the cooling system after fitting
-   Check the pipe route is clear and rising throughout, since a sag will trap the air this pipe exists to remove
