My engine is getting too hot. Where is the temperature sensor located in my vehicle?

Hello, the coolant temperature sensor is located at the rear of the engine on the coolant crossover pipe near the firewall.
I have attached a picture for you, hope this helps. Lou

Hello, I just replaced my thermostat, and now my temp guage does'nt work, well just barely comes of the peg, so I was wondering if my sending unit is bad, and if so, where is it

first ensure you installed thermostat correctly , if so then check the sending unit, it is at the rear of the engine in the engine coolant manifold on the 3.2L engine

The temperature moves to half when I make a stop at street light or stop sign and when I start moving again it goes down some millimeters back to cold, what can be causing his issue?

Also the thermostat was replace two and half ago.

Half scale on the temperature gauge is normal on most vehicles, but if you recognize that as higher than normal on yours, that is not the fault of the sensor. It is just reporting the temperature it sees. To go up when standing still in traffic can be caused by a worn radiator fan clutch. Stop the engine, then try to turn the fan by hand. When it's hot, it should turn with quite a bit of resistance.

The temperature sensor(s) are usually on or near the thermostat housing. There used to be two of them, a single-wire sensor for the dash gauge, and a two-wire sensor for the Engine Computer. Some manufacturers have dropped the single-wire sensor because the instrument cluster is now a relatively unreliable and very complicated computer module, and it gets it information to run the gauges from the other computers. Both of those sensors have an extremely low failure rate because they each only have one simple component inside. Almost all failures in that circuit consist of corroded or stretched terminals in the connectors. A failure in the two-wire circuit will be detected by the Engine Computer which will set a diagnostic fault code and turn on the Check Engine light.

Ok the thermostat was replace two months and a half ago and the fun clutch in May 2013, and yes the fun clutch is kind of hard when trying to turn by hand.

What problem are you trying to solve? Is the engine actually overheating?
