This post makes me remember my 86 crx dx fan used to run after turning the car off. Of course, it eventually stopped. My 91 crx si's fan never runs after it's turned off. Does this mean somethings wrong with it or is it designed not to? I'd guess your problem is a temperature sending unit gone bad, but like i said, mine never even runs when it's off, with a sohc zc motor(not b16a). I'm not sure if the different motor should have anything to do with it or not.
