-   Supersedes 3807108

## 🔌 Function

Carries coolant along a fixed section of the cooling circuit, holding the route between the components it links so the flexible connections only cover short movements.

## ⚠️ Common Signs of Failure

-   Coolant loss with white or coloured crusting at a joint
-   Header tank dropping with no leak visible when cold
-   Running temperature creeping up under load
-   Pipe corroded thin or pitted through on strip-down
-   Hose ends hardened and cracked where they grip the pipe

## 🛠️ Service Notes

-   Supersedes 3807108, so an order against the old number lands here
-   Renew the hoses and clamps at each end with the pipe - they have usually been sitting in the leak
