8" Electric Fan P/N 3660

8" HD Electric Fan P/N 3660

Late model cars and trucks have less and less room for the components required to properly meet the cooling demand of today’s transmissions. Small radiators do an inefficient job, and some O.E. coolers just don’t get the job done.

Hayden introduces a unique four pole, high performance, heavy duty electric fan, that when coupled with our 37mm heavy duty cooler, creates a self contained, compact cooling machine. Our distinctive staggered angle, high velocity blade, increases airflow while the stabilizer ring reduces airflow by-pass.


  • Heavy duty, high performance four pole motor
  • Staggered angle, high velocity blades to maximize airflow
  • Molded stabilizer ring to reduce airflow by-pass

8” diameter fan allows for many different applications:

  • Transmission cooling
  • Engine oil cooling
  • Custom radiator designs 
  • Longer life and more torque than standard two pole motors
  • More efficient operation, high velocity blades
  • Compatible with all Hayden fan controllers

Combine These Items to Create the Perfect Cooling Machine!
