Ok so i jus replaced the old radiator with a new one. but now the fan doesnt seem to kick in when it stars getting hot...
i hooked up everything correctly im pretty sure. even checked the plug for the fan and made sure it wasnt dirty or anything.
any ideas wat could have made the radiator fan stop workin?
93Civic BTW
THANKS A LOT!!

 

Check the coolant temp sensor. That regulates the fan on/off.

 

Jump the sensor which is on the thermostat housing. (Unplug the sensor and put a jumper wire between the two pins in the plug on the harness.) The fan should now come on as soon as you turn the key on. If it doesn't, check the fuse, which is in the underhood fuse box. Also check that power is reaching the fan plug. If you have power at the fan but it doesn't run, motor is bad. You can remove the fan and connect it to a battery as another test of the motor.

If the fan does come on with the sensor plug jumped, test drive like that and make sure there's no overheating. Replace the sensor (Coolant Temperature Switch) if the only problem was it not turning the fan on. If it still overheats with the fan running all the time, there is another problem.

 

Hey thanks!
yeah it was the fuse that went bad.
THANKS!
