## 🔌 Function

Routes coolant through the specified cooling circuit and maintains the correct connection geometry at the pump and adjoining hoses.

## ⚠️ Common Signs of Failure

-   Coolant seepage at a pipe end or formed bend
-   Corrosion, pitting or pinhole leakage
-   Overheating caused by coolant loss or internal restriction
-   Chafing or cracking from missing supports
-   Hose misalignment caused by a bent pipe

## 🛠️ Service Notes

-   Clean both flanges or spigots and check the sealing lands for pitting and corrosion; renew every O-ring, seal or gasket at the joint rather than reusing one that has taken a set
-   Lubricate coolant-side O-rings with coolant or a rubber-safe lubricant — petroleum oil and grease swell and soften the rubber and end up in the coolant
-   Offer the pipe up and align both ends before pulling any fastener tight, so the joints are not held together by strain from a misaligned pipe or an over-stretched hose
-   Check the bore is clear of scale, sealant and debris before fitting, and inspect the pipe for internal corrosion or thinning if the old one was leaking
-   Refill with the coolant type and mix specified for your engine, bleed the system through, then check the joints again with the engine hot and up to pressure
