my fan on my 92 civic si is not kicking in. this is causing my car to overheat. ive tried hooking my fan up direct and it works so i know its not that, i also just changed my auxilary fan switch, thermosdat, rad cap, and rad flush. Does anybody have any solutions. This is pissing me off

 

thermoswitch...its in the thermostat housing.

 

thats the one that i changed i guess its just a different name!

 

unplug the fan switch on your thermostat housing put a jumper or paperclip on the contact on the plug , now turn the key on if the fan runs fine then it's the fan switch or thermostat/ lack of coolant in the housing try bleading the system. if fan does not run then check fuses and relay or ground connection

 

Could it be a faulty thermostat? If yours is stuck open, then I'm guessing the car's thinking that it's not reaching operating temp, so that's why the fan isn't kicking in.

 

on the head, under the distributor one wire. next to it 2 wire, replace and try again.
