does anyone know if the cooling fans, on civic radiators or any honda/acura's engage at a certain speed or temperature. I took it off and the motor is still good, b/c I ran two wires from a battery to it, and it still spins. So if they do not engage while driving a certain speed, then i dont know what it is.

thanks guys,
mike

 

they come on at a certain temp controled by the 2 wire thermo switch on the thermostat housing,

 

kk thanks. do you usually hear it engage when it comes on, b/c i have never heard mine??

 

no they are very quiet when you are in the car, as long as the car is not running hot or overheating it should be fine
