You may need to replace the thermostat or water pump, even flush out the system. Best thing to do is to flush out the system with radiator flush and follow the instructions and replace the oil antifreeze with new one with a 50/50 mix (water/antifreeze), if you not sure how to do that you can buy them premixed. Next is to replace the thermostat and radiator cap, that should fix the problem. The last thing would be the water pump is weak and would need to be replaced but lets start with the simple., The other thing to if it's only hot when your at a stop light then check the fuse and relays and wire harness to your radiator fan to make sure it's working. If you turn on your A/C that would over ride the temperature sensor and activate the fans so you know that is working, so if's running hot all the time even when your driving, replace the thermostat and coolant. Good luck.

Smoke from engine and clugging noise then cuts off

I would trust the smoke and noise from the engine rather than a faulty temp gauge. have you checked the coolant level in the radiator and not the reservoir. The temp gauge will not give you any indication of overheating if there is no coolant to make it work

My 2007 Chevy HHR 2.2L, coolant temp sensor is reading that the coolant temp is 20 degrees warmer than the outside temp after sitting for over 12 hours and the operating temp gets to 214 degrees without...

Sure the engine coolant will be warmer than the outside temperture and if the car has been sitting a long time in cold weather and the outside temperture warms up it could be the other way around. The coolant temperture sensers aren't real accurate as they are a relaitive senser beween hot and cold and the numbers reported don't have to be real just the change from hot to cold and the reching of the coolant to the operating temperture. Noe it the senser doesn't read the opertating temperture coprrectly you'll have all kinds of problems. The therostaste will try to set the temperture of the water to it's set temperture and can open or close completly to get 195 degrees F. Many times if it's too cold then the stat is bad and needs to be replaced This shows up in alot of cars first thing after winter and the first onset of cold weather when the daily tempertures vary the most from day to night.

1992caprice over heating after replacing the thermostate

You either have the thermostat in upside down or you have an air pocket and the system needs to "burp". Sometimes this can be done by warming the engine and letting it cool down.

3.5v6 tempt gauge is not moving as engine warms?

Coolant temperture senser can be unplugged or bad. Coolant can be too low to touch senser. Coolant can be too much water and is'nt circulating as it's frozen and where the senser is it is still cold. The senser is in the left rear of the engine facing the firewall it has a two wire weathertight connector unplug the senser and with a papaer clip ground the wire and look to see the gauge go all the way if it does the gauge and wire are good and the senser or the water getting to it is'nt hot.

The gauge says it is hot, sometime it blows hot air and sometimes it don't? i've replaced the thermostat already

You still have air in the system. remove the radiator or resevoir cap and run the car to operating temperture, some coolant may come out at first because it's trty to purge the air. when you see that the coolant is going down, you can slowly add more coolant , as the car is still running

The temperture gauge does not work. It is always

Defective coolant temperature sensor if it reads hot as soon as you start the engine. Check the wiring before replacing. The gauge itself can also be bad but not likely. The temperature sensor will look like this. 52bbcec.png

1991 Dodge Spirit Check gauges light comes on when accelerating. Car seems to get hot according to the gauges and then cools immediately down.

The first thing you should check is your coolant level. If it is low add coolant. Next start and leave the car warm up to temperture and make sure the coolant is moving, have radiator cap off and watch the coolant. What you are probably going to find is that when the car is warming up or warmed up that the coolant will be low causing an air lock in the system. When the air locks happen you will find a overheat or running hot situation. This is due to air will not cool the sytem you need coolant so when the air hits the sensors under acceleration the gauges go high and cause the check gauge light to come on.

Driving down the road the temperture gauge pegs out hot and the engine starts to run rough and finally cuts off. Pull the battery cable to reset the electricals and everything is back to normal.

likely the coolant temp sensor. Some of those newish fords have a engine protection system that shuts down cylinders, then full shutdown if the computer gets a signal that the engine is getting hot.
Good luck!

It is over heating and i can't find the temperatre gauge under the hood...

first of all check the radiator for leak or blockage. make sure the coolant is fresh. follow th eupper radiator hosr to the emgine block. there should be 3 bolts attached the themostat housing. take the themostat out and put it with hot water, maks sure the opens. the temperture sending unit should be directly under the themostat. msot likely the themostat is cause or the problem. unless the temperture gage is not reading correctly.
