is there any way to leave fan on w\car off , and i cant seem to get my fan to kick on at idle, is there a manual way to turn it on so i can insure it is working? tia

 

Hook up a switch, directly to your battery.

Battery~Switch~Fan

I need to do this too, somethings wrong in my wiring somewhere, and the fan never kicks on. It overheated a couple weeks ago at the track. Pretty embarassing... It'll take some extra speaker wire and some electrical tape to put the switch in your cab. But then again, the fan isn't supposed to kick on until a certain temperature... Don't forget to turn your fan off when you go somewhere either...

My 84 CRX fan comes on all the dang time, and it stays on after I shut the engine off every now and then. Maybe you should look into that about some sort of relay that allows the thing to do that. Its all up to you man.

 

i was hoping it just wasnt reaching the temp at idle which i guess is possible as it has yet to overheat <knocks on wood> but just leaves me worried that it could

 

How 'bout replacing the fan switch?

 

how, where is it how can i tell if tis bad

 

bump

 

its a two prong sensor in the back of the block covered by a big black rubber thing. i think the wire colors are yellow/green and black.. i think now.

 

how can i test it?

 

what i would do is jumper together the two prongs on the switch. with the ignition on, the fan shoulw turn on. if it doesn't, your relay might be bad.

to check the CTS, you are supposed to suspend it from a pot of water and then heat the water up. once the water gets up over 190 degrees F, the 2 pins should have continuity.
