What This Fan Assembly Helps Address

  • Weak radiator airflow from a worn cooling fan motor
  • Overheating caused by reduced fan operation
  • Noisy or inconsistent fan performance
  • Cracked or damaged fan shroud components
  • Restoring cooling function on Buick Century and Oldsmobile Cutlass Ciera models

Installation Notes and Tips

Verify connector style, terminal count, and shroud fitment before installation. Confirm vehicle application by year, make, model, and cooling package, especially for 1989 Buick Century and 1989 Oldsmobile Cutlass Ciera without heavy duty cooling. Inspect the electrical connector and surrounding cooling system components during replacement.
