🔌 Function

The connecting pipe transfers coolant between sections of the engine cooling circuit, forming part of the sealed path that carries heat away from the engine. It maintains flow and pressure integrity between the connected cooling components.

⚠️ Common Signs of Failure

• Visible coolant leaks or staining at the pipe body or its joints
• Corrosion, pitting or cracking along the pipe wall
• Loss of coolant and rising engine operating temperature
• Weeping or seepage at the sealing faces after pressure testing
• Deformed or damaged pipe ends preventing a proper seal

🛠️ 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
