I have a 95 prelude s, with a jdm h22, my engine has 2 coolant switches, they turn on at a certain temperature, switch a turns the radiator fan. Does anyone know what switch B does?. I know A turns on around 196, B around 220 or 230, dont have my book in front, but it looks like the just turns the same fan on, is it suppossed to make the fan faster, or turn the ac fan on, or what. The reason I ask is cause if I remember correctly sometimes my fans would come on, after shutting off the car, for a few minutes, Im trying to figure out when its suppossed to do that, so I can figure out what I need to replace to fix it.
