Freon in the AC system heats up very hot before it is sent through the condenser. The condenser is like a radiator, and is located right in front of the radiator of your car. As air passes through the condenser & the radiator , the hotter the condenser, the hotter the radiator will be. correct answer the temp goes up when using a/c as the motor is running at a higher speed to drive th a/c , therefore when idling the fan is not pulling anuff air over engine. a thrmatic fan will help with this
Thermostat stuck open or no stat at all. Faulty temp sensor or Gauge.
Commonly check the temp gauge on the dash.
1min or 2 i like to wait till the temp gauge starts to move or let it get to normal temp.
Stuck open - no heat from heater, temp gauge hardly moves off of cold. Stuck closed - overheats engine, temp gauge quickly climbs to hot.
If you drive the car 10 miles, and it doesn't move.
A faulty thermostat might cause the temp gauge on the 2000 Nissan Altima to raise to hot when the car is not overheating. A faulty thermostat can cause the gauge to move up and down and might even turn the fan on.
Warmed car to operating temp with fan fuse pulled. Turned off ignition. Removed battery cable. This resets the computer. Put batt cable back on and fuse back in place and started the car. Temp gauge started working. (Sensor has to see temp within short amount of time to operate the gage.)
you could have abad temp sensor
The fuel gauge, temp gauge, and starter relay are on the same fuse (instrument panel). Does the car start? if the car starts then it is the module on the back of the instrument panel. it has 3 wires ( black, blue and yellow). once changed the guages would work fine.
that is not a question
I dont know who cares but you should go to a car garauge
Temp. sensor my have stopped working. Quick and fairly easy fix.
There isn't one. A warning light will appear if the car gets too hot
Sounds to me the coolant temp sending unit has failed. Replace it with a new one.
If your car only has one temperature gauge in the instrument cluster, it will most likely be water temperature. If you're not happy with that, you can buy after market water temp gauges and have one fitted.
In most engines the gauge and cooling fans have different senders, so if you have good hot air blowing inside the car from the heating system and the cooling fans on the radiator are operating, and still no gauge reading, you may have the wire disconnected from the temp. sender. The cooling fans can run after a car shuts down, as they are wired separate from the key on their own system, and will run until their sensor shuts them down.
You may have air trapped in the cooling system.This will cause the gauge to spike. Try this: remove the radiator cap and allow the engine to run for about 20 minutes. Add coolant as necessary. If this does not work I would replace the stat. Finally, I would check the actual cooalant with a thermometer to determine the actual temp. I hope this helps you. Mark
The 1995 Lincoln Town Car coolant temperature gauge sensor can be found on the front of the engine. The coolant temperature sensor will be a few inches above the thermostat housing.
The sun fades your paint. If your car is sitting in the rain, and then the sun. It doesnt just fade, it actually eats through the clear coat.
My Corsica's temp gauge went out, and to replace the OEM gauge would have required buying the whole instrument panel. We bought an aftermarket gauge and mounted it under the dash. It cost much less, and hey, it's not a show car so I don't mind that it's not 'perfect'. Just find the temp sensor on the engine (driver's side of car on back side of engine), and either use the sensor wire there or replace with one that works with your gauge.
Do a search for your ects sensor. I am trying to find out how many temp gauge sensors are on the car right now myself. I am having the same problem. I am going to change the temp gauge sensor(s) and thermostat and flush the radiator.
Sounds like a bad or loose ground in the dash some where
bodey thermistat mate
fuel gauge,speedomiter on instrument panel doesnt work on car and keeps stalling
