⚠️ Common Signs of Failure

• Coolant seeping or dripping from the sealed joint
• Ring found flattened, hardened or cracked on removal
• Ring swollen, soft or sticky from coolant attack
• Repeated coolant top-ups with no external leak visible

• Never refit a removed ring, and fit it clean rather than dry-scraping the groove
