replace engine fan

I used a replacement part from my mustang cobra. spal makes it and it was $139 dual speed fan. it fit the radiator very well without removing the shroud. $65 therm dual temp control.
I wired the low temp (180) output to the low speed fan input and higher temp (210) output to the high speed fan input.

This fan is the same fan that cools my Cobra's 409RWHP DOHC 32V motor

works very well. the engine seems more responsive to throttle input off idle.
I get a little better MPG as well, maybe 1 or 2.

I forgot to mention, you will also eliminate the start up whine from the stock belt driven fan.
