Check the coolant of the radiator if it "eats" up a lot of it... there could be leaks on the radiator, its cap and the hoses or the fluid is not that enough. Check also the water reserve beside the radiator if the water decreases as you drive. If it does not go down then the water circulation is not that good. There could be a leak. If there is no leaks then you should check out the fan of the radiator if it is working.

Vetra 1800 2004......temp gauge up and down,car seems to be running hot,only hot air out of vents,not heard fan come on 4 ages,any ideas?????


have your thermostat checked or remove it yourself car can run without it if it improves replace it with a new one these do sometimes get stuck ,if you do replace it always add antifreez to your water this also helps to keep your water and water jackets clean.

Hi have a 2004 freestar I changed radiator-, water pump , thermostat, engine coolant if I drive on flat street my van runs good temp is normal but if I go uphill the gauge goes up to almost red once I...


Sounds like a faulty temp guage/r a strange malfuntion in a sensor to me as well, only doing it when it going up hill really makes no sense for the way the cooling system works so I doubt that its actually running hot, which is likely why he asked about the gurgling noise, it would force water back into the resivoir if it was running hot assuming that the thermostatic radiator cap is working properly.

When the temperature outside is hot and I'm running the air, the temperature gauge starts moving into the hot zone. If I turn off the air, it goes back to normal. I've had it worked on several...


make sure that the coils, ( the ac radiator ) are clean , blow them out with an air hose if you can get a hold of one, also, make sure the ac fan is coming on, it may start , but the sensor may be bad allowing it to turn off too soon , a normal rise in heat is expected when using the AC but if it is too hot you should feel the motor start to run rough, if its running fine, and the temp does move back to normal when the ac is turned off, and a qualified mechanic has checked it, your probably ok, you could have a sensitive gauge, , If the normal range of the gauge moves to hot and back during normal driving without the ac on, that would show the thermostat is also working

06 Kia Sedona overheats when ac is on. If the ac is off the van will return to normal temps. Had the compressor just replaced and v-belt. Both fans appear to be running when ac is on.


Does the engine over heat or the gauge goes to hot. Really hot. Since the A/C is on , this puts an extra load on the engine. This is why the fans come on when the A/C is turned on. This is usually low speed fan mode. High speed doesn't come on untilll 220 to 230 degrees. Most vehicles. Cars don't over heat untill the gauge gets in the red, when it starts getting close is time to worry and stop. I guess the question to you would be, What does the temp gauge read?

2003 ford f-350 trans temp gauge shows hot, tow / haul light blinks steadily....what could be the problem


From what i know of these trucks, its a "common problem". There is a tsb on this and the gauges arent really accurate. The tow light is blinking due to heating(not really), its trying to tell you to stop towing. Ive read that some guys gauge is reading 250 which if it really were, the truck would be running. Water boils at 220(im sure u know that). Suggestions ive come across is adding aftermarket gauges that give "accurate" readings unlike factory ones that are controlled by computer. Aftermarket will give you independent readouts.Heres a temp check you can try on your truck, im not sure if it will work for your model.




This is for the regular dash, like in XLT.
key off
push trip button in and hold
turn key on
"test" will appear in message display. Release button.
Gauges will sweep
then just push the button each time to scroll thru various modes.
Mostly junk info, but eventually you will come to temp, it is in Celcius so you have to convert to Farenheight(temp x 1.8 + 32)
Normal temp for mine at idle is 88, so 88x1.8=158.4,+ 32=190.4F
You can also view digital tach. All these modes are real time, and will remain on until you cycle the key on/off.

DId anyone ever find out what "ENGINE HOT/AC OFF"


The only way to know for sure is to use a scanner to see what the PCM is seeing. You may have a bad sensor, a inaccurate gauge or possible a PCM issue.
Do you really want to guess at this point ?? because even with a guess you will need to verify it with the proper tools.

2003 chev impala 3.8 the temp gauge goes up 1/4 of the way..what shd the normal reading go to I wld think 1/2 way on the gauge? I just think the air shd be hotter when set on hi


During the winter time the engine may not produce enough heat to go half way. You can modify this by installing a hotter thermostat. But I would not go more that 20 degrees F though, or you could create issues for summer driving.

96 mustang v6 temperature guage reads around the "m" letter on guage, and even at "a" letter on the "normal" area of guage readout....seems like it's running a bit hot, but i'm not a ford expert. I got...


some of the factory gauges aren't very accurate if the fluid level is good and you get good heat inside I wouldn't worry about it, but I would keep an eye on it to make sure it doesn't over heat. If your still worried I would go to an auto parts store and pick up a temp. gauge there perty easy to install
