I guess I'll fill you guys in on a cheap and easy electric fan for your s10. I found that the fans and shroud from a 1993 to 1997 dodge intrepid or chrysler concorde fits perfectly inside the radiator of a dime with a 4.3. i think it will fit in one with a 4 cylinder. I know the radiators are alittle smaller. Might have to trimm some more.
I'm not big on secrets. When ever I can save a minitrucker a few bucks. I will.
Here's a link for one on ebay. Only bad thing about this one is you got to find the other end of the wiring harness. I found mine at a salvage yard. There's a ton of them out there.
