Just finish my swap B16a2 in a 92CX everything fine. Now here is the problem dam thing be overheating. I'm using the radiator from the 99SI but the fan won't come on I then slice up the wire and attached it to the battery and the fan work fine. I let the fan run awhile still the car temp. won't come down. The motor is under 25k miles everything check out fine. Can someone tell what to do?

 

does the ecu light come on, if so you can check that. It sounds like either the temp sensor, or perhaps the switch that engages your fan.

 

Well, if the fan is running and still getting hot, it might be the water pump, sheck that ou, if you didn't change it when you did your swap, I recommend that.

 

also check the thermostat
