Question about 2001 Kia Optima

1 Answer

I have a 2001 Kia Optima that over heats

It's a V6 with roughly 170k miles. When i drive it, the temperature gauge slowly raises. This started last week. I made sure there is coolant in the reservoir and the radiator cap. There aren't any signs of leaking. The fan works as well and i don't hear any 'odd' sounds. The AC doesn't affect the temperature level and in fact, nothing that i do raises the temperature(other than just driving it). I want to get it diagnosed but i don't want to spend a bunch of money if i don't have to. Thank you

SOURCE: 2001 Kia Optima over heating

I figured this out and fixed it on my 2001 Optima. Mine was an electrical problem, not an overheating problem. The problem shows up when there is a heavier than normal load on the electrical system. For most of us, this is when the air conditioner is running full-blast on a hot summer day. However, it was also occuring when I ran the heater full blast. The heater running full-blast should have lowered the temperature, not raise it. So I tested the coolant temp while the gauge was showing it overheating. The coolant temp was not increasing, but the gauge showed that it was. It is caused by a bad ground connection. Another test you can do to see if your problem is the same as mine is this. As soon as the engine is showing overheating, pull over, park the car and turn off the engine. Immediately start the engine again and see what the temp gauge shows. If it still shows hot, you'll know you've really got overheating coolant. If it goes back to normal range, you'll know it's just a bad ground connection. Turning off the engine eliminates the resistance in the electrical system that has beeen building up and causing an erroneous high temp reading.

To fix: Either find and clean ground connections throughout the vehicle until it fixes it, or do what I did. A mechanic at the Kia dealer showed me this. I ran a new wire from an empty bolt-hole on the top of the engine to a bolt into the frame behind the engine. I only added a 6 inch wire and a new bolt into the top of the engine. The bolt into the frame was already there, so I just removed it, put the wire under it, and replaced the bolt. It created a redundant ground that prevented the build-up of resistance that caused the erroneous temp reading. It was a 5 minute fix and it has never done it again. Kia knows about this problem and they put out a post to their shops on how to fix it.

have your thermostat checked as it may be sticking, also your catalytic converter may be on it's way out.

SOURCE: leaking antifreeze

the location of the leak needs to be identified. it could be as simple as a hose or a leak in the block. sounds like you need to find a trusted technician to find the source of the leak and repaired before it causes more substancial damage.

SOURCE: 2001 Kia Optima - Train sounding noise underneath

Sounds like the bearings are going out in the rear hub(s). Drive the car for a few miles (if it is safe to to do). Park it and check to see if the wheels are warm, or even hot, in their center cap area. This will indicate excess friction from bad bearings. Replace the whole hub. It's an easy DIY job, if you are so inclined. Part cost should be just over $100. per axle. Shop around to find a good price. I recommend Timken hubs. best of luck.

SOURCE: 2007 Kia Spectra has coolant loss. Pressure test

in this case i would suspect the water pump,it would not really show up in a pressure test ,put a paper liner under the car at night and see if any water shows up on it in the morning,if it is ok, then the water could be lnternal ie the engine is taking the water,but 2007 engine should not have this problem unless it has a very high milage.one more [simple] answer is the coolant leaking from a simple loose conaction and drying up before you see it ,but water leaves a trace so have a good look about the engine for that water mark,please rate this answer.adrian,,,,,,,,,,,

make sure that the coils, ( the ac radiator ) are clean , blow them out with an air hose if you can get a hold of one, also, make sure the ac fan is coming on, it may start , but the sensor may be bad allowing it to turn off too soon , a normal rise in heat is expected when using the AC but if it is too hot you should feel the motor start to run rough, if its running fine, and the temp does move back to normal when the ac is turned off, and a qualified mechanic has checked it, your probably ok, you could have a sensitive gauge, , If the normal range of the gauge moves to hot and back during normal driving without the ac on, that would show the thermostat is also working

It's possible that your oil level is low or it's time for an oil filter change.
If not, it's possible that the rockers need adjustment, but I doubt it. Good luck

Am about to buy a used car KIA Optima V6 2003 with 65000 miles on it. What are the common problems with this kind of car? I never had one before though it looks pretty cool


I have a 4 cylinder 2003 Optima and I'm having all kinds of trouble with it. I got it last year and it had 76000 miles on it. When I bought it, the driver's side rear window didn't work, and the locks were iffy on unlocking with the button. NOW, it has 103000 miles and I need new axles, already had to get a new timing belt, the driver's door lock is broken (can't unlock from the inside OR outside), and the gas tank is screwed up. Don't think I'll ever buy a Kia again.

Seems you have 'MULTIPLE' possible causes for this problem. First of all, I'd have a mechanic (a smart one) check the Throttle Position Sensor (TPS) first, Usually, the TPS does have a direct effect on trans shifting erratically. It's also used by the ECM (Engine Control Module) to calculate 'LOAD' and subsequently the Fuel Mapping (fuel to air ratio, ignition timing, etc) which could possibly create a RANDOM MISFIRE condition. This other description you have regarding 10 minutes - that one's wierd - could be a multitude of possible causes (i.e, fuel pressure not enough or too much, malfunction in the Engine Coolant Temperature (ECT) sensor, malfunction in the Intake Air Temperature (IAT) sensor. First things first - get the TPS checked - if found bad - replace it. Go from there.
