• Green or white corrosion on the contact faces
• Body cracked or a locking tab broken off

🛠️ Service Notes

• Compare the new connector against the old one for size, form and number of ways before fitting; connectors that look alike are frequently not interchangeable
• Renew any seal, gasket or O-ring that belongs with the connector rather than reusing the old one, and check the mating faces are clean, dry and undamaged
• Support the connector and the line or harness running into it so the joint carries no weight or side load, and keep the original routing and clips clear of hot and moving parts
• Push or thread the connector fully home until it seats or locks, then confirm the lock has engaged rather than assuming it has
• Prove the joint before closing up the access — check it for leaks or for correct operation, whichever applies to that position, with the engine run up
