Question about 2005 Kia Optima

2 Answers

I have a 2004 Kia Optima and about a week ago it started overheating. We replaced the thermostat and still the same problem. It happens mainly after running the air conditioning but now it has started happening both with the air on and off. Nothing is leaking so I am stumped.

    I have the exact same problem. I guess I won't replace the thermostat since that wasn't your problem and I'll look at the water pump maybe being the culprit. I just had my radiator flushed so it shouldn't be a clog, and the fans run just fine.

    hey guys, it sucks, i got the same problem, at the time i'm replacing radiator, let me know if your h2o pump helps, i've also in the past changed my temperature sensor, not it...

    Hey, how did the radiator replacement go? I'm in the same exact boat and have removed the radiator but am trying to figure out how to fit in the replacement.
    KIATechInfo says to take the whold fan/rad assembly out, they also skip several steps like "take the condenser bolts off" and other fun stuff that turns out is necessary.
    Anyway, I was able to get the rad out but had to remove the fans first, I don't remember how I got the bigger driver side fan out but I'll be damned if I can get it back in. Too much **** in the way.
    I have an 01 optima which should be the same as any other Optima 01-06.0 (not 06.5). If I would have known I couldn't take the fans out with the rad I wouldn't have gone underneath to remove the hoses....
    Anyway, how did you jimmy those fans back in there?

engine running too hot.check coolant level, should be 50/50 antifreeze and water.replace thermostat and radiator pressure cap.check antifreeze level in the radiator,coolant level should be just below radiator cap, add coolant to overflow jug,should alway be at the full cold mark.empty coolant overflow jug will allow air be drawed in the coolant system causing overheating.if overheating happens when coming to a long stop.could have faulty engine coolant temperature sensor or bad coolant fan fuse or relay.

I have a 2004 Kia Optima and it left me stranded on the road, came to a complete stop, I turned off the ignition then turn the key again and it started up fine. It had happen a couple of weeks ago and...


You need to have the codes checked. when you cycled the key , you were resetting the ECM. This didn't fix the problem. Get the codes and let me know. We can go from there. There are to many things to list that can shut down engines. And you don't need to buy expensive parts that you don't need.

Kia optima LX 2004 shut down at about 50mph


was it the timing belt or the serpentine belt that was replaced (not the same item). It's possible the previous service may have had something ot do with your current problem but I'ts impossible to tell from here. I was once a professional warranty inspector and even hands-on with your vehicle it would be difficult to draw any connection between the two failures. If you do not trust the shop or technician that works on your car, don't use that shop. Trust and confidence is important but must be earned.
