You might want to chk. the connection on the sending unit and temp. sensor thats the way they act when they loose a connection. If that chk. out ok then it would have to be the guage its self thats faulty.

Temp gauge working


Could be the temp sensor that is screwed into engine is bad or the gauge is bad. Have both tested.

Temperature needle stays on the hot and doesnt move even when the car is cold?


YOur guage is faulty. Your will need to replace your guage if it stays in the hot position even when your car is off and your key is out of the ignition. If it only rises to hot when you turn the key to the run position, you have a wire between your guage and your temp sending unit that has been gounded out. Usually this happens when a person opens their hood to add oil or perform some minor maintenance on the engine and inadvertantly bumps the sensor or switch or wiring. This causes about 65% of these minor issues people incur, but if it does stay all the way up with your key out of the ignition switch, then you will need to replace your temp guage.

Temp guage in red' dummie light on engine not hot


Sounds like a faulty sensor, if the actual temp is 195/215. The ICM is processing the information it receives from the sensor and performs accordingly. A complete diagnostic scan would be helpful in determining the proper repairs needed to correct the problem.
Good luck...i hope this helps, please rate me a fixya.

Choke coming on even in summer, is this right


it seems that your coolant temp senor is what causing this to happen it's natural inless it revs really high and stays above 1100 rpm's after the engine heats up.

I drive about 260 miles a day. my 1999 dodge truck has been running about 210-230 degrees. i drive about 70 mph. if i slow to 55-60 the temp stays 210.


seems high to me. summer thermostats open at 185 , winter thermostats open at 195. At highway speeds , there should be more than enough air flow through the radiator to keep engine in the normal range. Your radiator might be pluged up and cooling poorly , but I suspect your temp guage might be inacurate.

95 ford taurus stalls in very hot temps. every summer. Fuel pump?


When this happens have you noticed what temp guage said? if it was hot then you might try a lower temperature thermostat and flush coolant system.If it doesn't actualy get hot coolant wise then a vapor lock in fuel system would be unlikely to my knowledge, car has fuel pump in gas tank and is fuel injected.If you only take short trips in car cooling system,<thermostat,water pump,coolant level and radiator> could be at fault and only when running for longer periods of time might cause overheating and not noticed on regular days on short trips.

TEMP GUAGE


There is 1 Relay Switch and a Fuse that Operates this Guage Also. Check in the Fuse Boxes for these first.
