Needle on temp guage stays on COLD, doesn't move.

i would think there is an air lock in the coolant system , have you run the engine whilst at stand still and opened the heater control to the hot position and leave to run for 10 mins or so , let cooldown then check coolant level

You need to replace the Temperature Sensor.

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.

Chances are you need another speedometer, or send that one to a shop to have it fixed.

Not uncommon for oil pressure to read @ 80psi when oil is cold an thicker or a heavier weight oil, however, does it fluctuates or simply stays @ 80psi cold or at running temp? if so, its normal, if it stays there and doesn't move, that may a bad guage or sending unit. consider this and get back. I am a mechanic . TH

replace the thermostat,, and make sure that the fan engages , just because the fluids don't boil over doesn't mean the temp isn't to high, if your saying that the temp gauge is stuck on the hot setting, and doesn't move even when the car is cold,, thats a different problem,, if thats the case whats the make , model , and year

ok mine did this untill i got an air pocket out of the coolent system then it was find.

Hi

Does your temp guage needle drop to Zero when you switch off ignition ?

If not, your temperature transmitter is faulty, or the wire running to it is earthing out somewhere.

Hope this is of help.

Good Luck !

follow the upper radiator hose to ehrer it connects to the engine, the t-stat is right there
olso remove all that other stuff in needed

The wiper switch is most likely bad. Check the coolant level for the temp. issue. Low coolant will cause a gauge to shoot up suddenly
