⚠️ Common Signs of Failure

• Coolant weeping or crusting at a joint or seam
• Pinholes or corrosion pitting along the pipe
• Sealing faces or hose stubs scored or corroded
• Pipe knocked out of shape so the hoses will not line up
• Coolant level dropping with no obvious external leak

🛠️ Service Notes

• Renew the seals or O-rings where the pipe joins, and clean the stubs back to bare metal so the hoses seal
• Pressure test the system after fitting and check the joints again once the engine has been hot
