i used a 91 crx si block which does not have the fan switch located on the thermostat housing . it went into my del so which uses that sensor to turn on the fan. for now i have it on a manual switch but id rather have it right. i checked if the thermostat housing from my block would work but it doesnt fit. any ideas?

 

Go to honda and get another switch. Or a junkyard.

 

try the mugen fan switch. kind of pricey but i believe it should work. good luck.

 

its not a bad switch , its that the 91 block thermostat housing does not use that sensor so there is none. but my 93 del sol block did use the sensor so the block doesnt have one at all

 

Wire up the fan to run constant. I believe thats the easest thing to do.
