For your cooling fan needs go back to this thread here on CC, (the Lincoln or Taurus fans)

These 2 speed fans are complete with a shroud and easy to mount not to mention they are like 60 bucks at a wrecking yard. They do KICK A$$ but you will need to install proper wiring because they pull 28 amps on high!!
Sounds like you might have a wiring issue that is under suppling amperage and burning up your earlier fans .??
