Probably not what you want to hear ,First loose the flex fan they look good but I have had problems with every one I have had,

Second and Most Important is you need a shroud the cut out needs to go as close to size of your fan as possible without touckind ,don't forget engine torques to the right , and the fan blades need to set inside the shroud about 75% only 25% out as this will force All of the air through complete radiator not just the diameter of the fan ,,or use an electric fan and a shroud (,my 1st choice,). if you use a clutch fan try to find the one with a spring and oil viscous coupler I will cool at idle and disengage at highway speeds .
this puller setup works for me.
