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

Why would my temp gauge shows the car not hearing up why does the car has heat how come fans run after car is off?
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.
Why would a temp gauge in a car go up like the car is going to overheat when the temp gauge sytem light stays off?
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

How do you fix the temperature gauge on a 1991 V6 Chevy Corsica?
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.
