## 🔌 Function

The connecting pipe carries engine coolant between cooling system components, completing a sealed section of the circuit. It maintains coolant flow and pressure so heat is transferred away from the engine.

## ⚠️ Common Signs of Failure

-   Visible coolant leaks or staining at the pipe or its joint faces
-   Corrosion, pitting or scaling on the pipe body
-   Cracks or deformation from vibration, impact or over-tightening
-   Persistently low coolant level or repeated top-ups
-   Rising coolant temperature caused by restricted or reduced flow

## 🛠️ Service Notes

-   Renew the O-rings, seals, gaskets and clamps that seal the pipe rather than reusing them; most leaks after a pipe change come from a reused seal
-   Offer the pipe up and get both ends aligned before tightening anything — pulling a rigid pipe into place strains the connections and cracks flanges and fittings
-   Check the bore for scale, corrosion and debris and clean the mating faces on both components before assembly
-   Refit every support bracket, clip and piece of insulation; an unsupported pipe fatigues at its joints from engine vibration
-   Refill and vent the system, then leak check the joints and check them again after the first run up to working temperature
