⚠️ Common Signs of Failure

  • Coolant pushed into the expansion tank or lost through the overflow
  • System not holding pressure, with the engine running hotter than normal
  • Cap seal hardened, split or swollen
  • Spring weak, so the cap releases below its rated pressure
  • Filler neck sealing face pitted or scaled

🛠️ Service Notes

  • Pressure-test the cap rather than replacing it on suspicion, since a weak cap and a leaking system give the same symptom
  • Applies up to serial number 5312820656, so confirm the engine serial before ordering
