Hey guys I got a b18c in a 99 si. I did my swap about two weeks ago, and I noticed my fan hasn't kicked on. My car hasnot run hot at all. So what should I do? My friend told me too let the car run for 20 mins and listen for the fan but it did not ever work, Help guys please?

 

well if your car is never overheating, it prolly just has a really efficent cooling system. if the car starts to overheat that is when you have a problem. but you could hook the fan motor up to a power source and see if the motor is still good.

 

its ok, running at idle sometimes doesnt produce enough heat to kick the fan on. if the motor is broken in then go haul *** around for 10-15 minutes then hop out and check the fan.

 

Could be the relay or the actual fan. Also check the wires and connections.
