ok im using 16 inch flex its steel because it reverse rotation as im using a sep set up my question is should i do away with it and go to all elec fans or just add a back up elec fan it run 170-190 on open road and has got up to about 225 in town and when it gets that hot it wonts to cut off so do i just add an elec for town or what.. obtw its a 94 and i set 4.3 rad forward and inch and kept a/c have an inch between the rad and fan and i have only the top pice of the shroud ...had to cut it to fit around alt and a/c comp. so really i have no shroud just a finger guard lol thanks for any help

you could make a shroud yourself from lexan or other flexable plastic, and add a couple 10\" fans in the front it should run cool then

ok i also bought a 17 inch flex i have not had time to try it gonna change it this weekend one inch bigger fan should help some...thanks for your in put i just have it all pretty close and dont want to have to redo a bunch of stuff think ill leave the 17 flex at one 10 inch elec and try that for now and maybe some water wetter what ya think thanks

stay away from the flex fans..... they can come apart, i dont care what rpm they say that can handle..... get a steel clutch fan they are the best, i have a race clutch fan without the clutch..... it may be drawing some hp to turn it, but its well worth the extra cooling!

its a steel fan made by flex 1517 i think rev rot i use a serpt system..i\'m only gonna be turning it around 4800 so not to worred about it flying apart..

I like electric fans better less parasitic drag and they can cool your engine at a high RPM even while the engine is idle

I had a 17\" steel flex fan that was brand new on a 91 s10 with the 2.8 and at about 2000 rpm it came apart and I to had replace several peaces

Im running a Flexolite #210 electric fan set up with adjustable thermo, and the 4.3 radiator.



Fan completely cover the radiator fins like it was made for it, and cools excellent. Hasn\'t gone over 195 in summer heat.





Pulling airflow through the radiator completely and evenly is the key to a good cooling system. If you go with a electric fan set up, run pullers behind the radiator. They will cool better.
