I have a 97 Caddillac Eldorado and it is overheating. It doesnt happen all the time, but when I drive for longer periods of time it starts to over heat. It doesnt have any leaks and when It starts to over heat, if I cut on my heater in my car the temperature gauge will go back to normal. Please help me find the problem.

It's called your thermostat...and it's not opening up properly. Not an expensive part to fix and it usually goes at some point or another. Don't stress too much about the cost but get it fixed ASAP

There are many thing that may cause this to happen.
First check the water level. When was the last time you drained and flushed the system? It should be done every two years, antifreeze wears out. Your radiator may be partially plugged up.
Your electric fan may be going out too. Since you say it takes a long time to heat up, the fan motor may be getting hot and dragging. Your car also may be running too lean, this will make it run hotter. Thermostats usually fail open or closed. If closed you overheat quickly, if open, the engine never warms up in winter.

Start with the easiest least expensive fixes and work your way up. Those cars were susceptable to gasket failures so make sure its not a head gasket failure before you do this other stuff. The radiator fluid GM put in those cars ate away the gaskets. It was suppose to be lifetime stuff but was a defective product. If your not losing radiator fluid your probably ok.
1. check that the electric fan is working properly
2. replace radiator cap
3. replace the thermostat
4. have the radiator cleaned and rotted out
5. replace the water pump

The thermostat may be hanging up and just starting to fail. I'm not sure if you have the electric fans or the engine driven fans. If the electric fans be sure that they are functioning, it could be a temp sensor or a blown fuse. One way to check the electric fans is to start the engine and turn on the AC. The fan should turn on and run. good luck.

It sounds like your radiator may be getting clogged up - you can try draining it and flushing it out to see if it helps. Change the thermostat while you are at it.
A water pump that is going bad can cause the same problem.
If it overheats when sitting, it might be a bad fan or fan relay.

the heater core is acting as another small radiator blowing air through it, symptoms sound like one of two things, your clutch fan may be bad, which makes the fan engage at low speed, or your radiator needs rodding out, look down in the radiator and start it, see how well the water flows through the cooling vanes.

i would start with the simple things like replacing the thermostat and if that does not help than i would have the radiator checked to see if it is plugged.
