🔌 Function

Seals the radiator/CAC service plug against coolant or charge-cooler leakage.

⚠️ Common Signs of Failure

  • Leakage around the plug
  • O-ring cut or flattened
  • Ring hardening from heat
  • Repeated leakage from a corroded groove

🛠️ Service Notes

  • Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
  • Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
  • Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
  • Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
  • Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
