🔌 Function

⚠️ 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
