🔌 Function

Spaces and centres the cooling fan on the drive hub so the blade runs at the designed position inside the shroud.

⚠️ Common Signs of Failure

  • Fan blade contacting the shroud
  • Incorrect fan-to-radiator clearance
  • Adapter cracking or fretting
  • Fan vibration or run-out
  • Loose mounting screws

🛠️ Service Notes

  • Check the adapter against both of the parts it has to join before fitting — adapters are specific to an engine and its variant, and one that is close but not correct will not seat or seal properly
  • Clean and inspect both mating faces or connector ends; grit, old sealant or corrosion on one side is the usual reason an adapted joint leaks or works intermittently
  • Renew any O-ring, gasket or sealing washer belonging to the joint rather than reusing the old one, and lubricate rubber seals lightly so they slide into place instead of rolling or nipping
  • Tighten threaded adapters to the figure given in the workshop manual for that connection; many go into aluminium or onto a soft seat and will distort if pulled up hard
  • Where the adapter is a workshop tool, check it for thread wear and damage before use and never modify it to make something fit
