Most likely the coolant sensor is bad......The sensor has probably cracked and leaked into the harness, causing the harnes to corrode. Very common problem Check the sensor first!!!!!
Not neccessarily it sounds more like it could be a thermostat problem,water pump not pumping at capacity I mean there could be a clog but highly unlikely would'nt life be grand if all our automobile problems were simple and cheap ones head gasket problem is another culprit but start small and work your way to the big problems the cooling system is a pretty simple system aside from the Engine Coolant Temperature Sensor which I have seen cause problems that you would think it could have nothing to do with give that baby a once over as well

^^^^NOT a thermostat issue. Thermostats are designed to be open when/if they fail. The car would always be cool if the thermostat was bad. Also, because the ECTS has NOT been replaced the gauge can NOT be used as an accurate temperature reading. The PCM uses the sensor to control the fan power. If this sensor is bad then the PCM will not turn the fan on, thus allowing the car to over heat. Replace the ECTS ASAP and move on from there if the issue is not solved!
a thermostat stuck open in fail safe mode WILL cause overheating because the coolant free flows and doesnt have enough capture time in the radiator to let the fans cool,hence the degree ratings on the thermostat for various climates.give good info or dont give it.a removed thermostat or a free flow stuck open will not allow enough cool time for coolant.stopping flow give the radiator and fans the gradual cooling time needed to accomplish this.
Flush radiator
Yes! Also a good flush will improve its performance. And may stop the overheating.
The radiator on a 1995 Saturn is flushed by draining the coolant, refilling the engine with water, and adding a flush. It is allowed to circulate and drain before refilling with coolant.
Take it to an oil and lube shop and have them flush the radiator.
Check the tension on the belt, it may be slipping. If tension is okay, you might need to flush the radiator or the entire cooling system.
Have ALL the fluid drained and replaced with the exact fluid that Saturn recommends. Use not other fluid. Do not flush.
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
Engine overheating is a good indicator. Some people get them flushed regularly as part of regular maintenance.
Thermostat would be my first guess, If not is a fan blown, do a radiator flush?
Drain and flush your entire cooling system.
Replace radiator ASAP. And flush tranny fluid.
In order to flush the radiator on my 1996 Safari I had to remove the radiator fan cover under the hood (there are 6 bolts holding it in place). You will find a plug on the bottom of the radiator that has to be unscrewed and the old water will drain. I ususally put a hose in the cap and let the engine run (with the heater on) to flush out all the old fluid. Then re-plug the radiator, re-install the fan cover and re-fill with fresh fluid.
