    Is it overheating according to the temp gauge or do you have steam coming from underneath the hood?

One of the common things that gets missed at times is the radiator is down in cooling antifreeze. The car will act as normal during the warm up cycle and then the temperature guage will rise and then it will slowly come back down as the thermostat opens and/or the electric cooling fans come on. In actuality the engine is overheating, but it is not boiling over. The level of abtifreeze is at just the right level of lowness that you experience this phenomenon. After the engine cools off , (DO NOT REMOVE WHEN HOT - YOU CAN GET SCALDED WITH BOILING WATER/ANTIFREEZE)), remove the radiator cap and check the level within the radiator and also the antifreeze reservoir level. You can buy a 50-50 mix of antifreeze and water that is ready to put into the radiator. If the level in both the radiator and reservoir are correct, you may have a bad thermostat or some other problem.

Trying to locate the coolant temperture sensor on a 2003 nissan sentra gxe


Engine coolant temp sensor should be on the drivers side of the engine block. Follow your top radiator hose from the radiator to the engine block. near that you should see a sensor (it has a clip on it where the wires attach).

I own a 2003 sentra 2007 GXE. Last week The


Sounds like it could be overheating. Especially if your wife is driving slow speed through town then there is less air going thru the radiator and the electric fan should take care of that. The reserve does not need to be full but should not be completely empty. When the engine coolant heats up it is pushed into the reserve tank when hot and then gets sucked back into engine when it cools. Anyways the first thing I would check is the radiator electric fan. If the fan is not working then the engine will overheat if stopped or at non-highway speeds. Check the fuse is good and make sure the fan relay is working. There is a seperate fan that works for the a/c and if you notice it start running rough then turn on the a/c and that will kick on the other electric motor to help cool the engine(just hope it is not winter time). You could let the engine idle for a while and see if the fan comes on. The mechanic using the computer has the ability with that computer to actually tell the car's computer to turn on the fan that way he can verify it is working. Sometimes thermostats go bad and can get stuck closed and cause an overheating issue also. So you could also replace the thermostat. Let me know if you have any more questions.

I cant find the sensors for my engine fans its a nissan sentra gxe 2003


Chances are it is not the coolant temp sensor. The sensor is located right above the alternator, if you have the smaller engine. I wouldn't touch the sensor if you don't have a check engine light on.
