    I did the thermostat myself. Only has main fan no electric fans. Car is actually a 1993 model.

    wondering if it could be water pump?

    OK . I have to ask,...who did the thermostat ? Is your radiator fan coming on when engine at normal temperature?

    You can usually tell by looking when you have the cap off the rad, and thermostat opens, you should see the flow circulating through the rad.May take a trained eye, but a good flow rate tells me the pump is ok. if you have very little flow, then yes I'd start thinking water pump.
    How about your heater, is it giving heat good? Does it heat up whether idling or driving down the highway?

Sounds like you could have some junk in your coolant system. I would try a complete flush maybe a couple of times with just water pumping through. you can get rust in there and even with a new thermostat as soon as a chunk of rust gets back to the thermostat ot can stick closed again.

While driving mt collant temp light come on.


Check the radiator ( not hot) and overflow/fill tank for proper levels. Check under the car after parking for any leaks. The temperature is usually read at the thermostat, so it may be stuck closed , causing overheating, and the light to come on. Thermostat is an easy fix. If the car has been overheating you will need to change the thermostat anyway. The car will run fine in the summer without the thermostat , so at least take it out and see what happens.

1997 cadillac eldorado running hot


Make sure you put in the correct temp thermostat. GM usually has 2. A low temp and a high temp. Most shops will give ya the high temp just because thats usually what the book calls for. you might want to try a low temp. Also, sometimes, when a car runs hot and everything has been repaired....well, almost everything......it might be the head gaskets. And those my friend are no easy task. But..somewhere to start. have your cooling system pressure tested. Only way to really know for sure. Oh..also make sure your fan is working!!!! You might have a faulty fan switch.

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.
