My engine is basically brand new (3000 miles), I decided I didn't want the fan clutch (sounded like an airplane, never mind how much HP id drains). I bought a 16" curved blade fan rated at 3000 cfm on ebay (I'm a cheap ***). I then had a friend fabricate a shroud out of aluminum using the original plastic shroud as a template. to fit the fan I bought.
This fan is rated to cool a big block. The fan switch that came with it was junk! fan came on at very low temp & stayed on until a very low temp.(was suppose to be on at 200 & off at 185). I ended up getting a sensor from Be Cool (from Jegs) that comes on at 210 & off at 185. Tried it last night & it works perfect. Then put the AC on & let it sit & idle. The front little ac fan came on & when the temp got up to 210 the big fan came on for about a minute & went back off like it should. I think this will work fine. Obviously I'm not in the southwest to test it,but Im pretty certain it's gonna get the job done this summer. I think the problem people have is the shroud!
