Question about 1998 Kia Sephia
My '99 Kia Sephia overheated a few times and the coolant boiled out at the end of my trip and when I parked. I flushed the engine cooling system, changed the thermostat and the coolant. The problem didn't go away. I inspected the water pump and it seems to be working properly. Upon further inspection, I noticed that the fans didn't turn on no matter how hot the engine got. I tested the fans by hooking them directly to the battery and they work fine. The just don't turn on when they are supposed to. I will change the relays, the Intake Air Temperature sensor and the radiator cap. I don't know what els to do. I'll report back when I make the repairs.
Rplace coolant temp sensor,and bleed all air out of coolant system ,fan relay checks and fuses check is good,,do fans run with ac on? if they do ,fuse and relay most likely ok but check relays any way

Hey, my car is experiencing the exact same thing. i did everything you've done, and i found that the fan motor relay is causing my problem, i jiggled it around and it the fan started to work. I then saw that the wire from the car into the relay was a little damaged and burned. fix the relay and it should be okay. that's what I'm going to do today.
