⚠️ Common Signs of Failure

• Coolant weeping or crusted deposits at the flange joint
• Flange face corroded, pitted or scored
• Cracks around the bolt holes
• Joint not pulling up square, so it will not stop seeping

🛠️ Service Notes

• Renew the sealing components at the joint whenever the flange is disturbed rather than reusing them
• The name changed at the supersession, so an older list showing connecting flange 425728 points to this number
