The fans dont start til temp reaches redline on temp gauge.

The fan is controlled by water temp sensor to keep the temp between 160 (fan off) and 190 (on). Is the temp gauge going into the red? Is the temp sending unit for the gauge correct? The fan will run continuous with A/C on. Also check fan relay for over heating.

is the cooling fan cutting in ? run the engine whilst stationary with the hood up , give it a little gas 2000revs and wait for the temp gauge to rise ,the cooling fan should be heard cutting in , and off again once cooled the engine temp down ,this may take 10-15 mins but you have to be sure the fan is cutting in or you may cook the engine

do you have a temp gauge or light? make sure the radiator is full, if you have a gauge start the engine and let it idle for about 15 to 30 minutes and see how far the gauge will go up but if it almost reach the dangerous zone turn the AC on and see will the gauge move back down to normal zone if the gauge do move down that mean the cooling fan is working with the AC on but if the gauge do not go down with the AC on that mean the cooling fan is not working you can check the cooling fan by connecting the red wire to the + post on the battry and the black wire to - post on battry and if the fan work it is good then check the cooling fan relay and wiring.

The most common reason would be a bad thermostat or the car is low on coolant, check the coolant level make sure the engine is cool and check the level, if the level is full then i would say to replace the thermsostant, the thermostat is what regulates the flow when it reaches a certain temp, also take note that the fans on these type cars dont come on until they reach a high temp, the gauge on them reaches close to 3quaters the way on the gauge before the fans run, good day.

You probably need to bleed the cooling system properly.

Open the cooling system bleeder screws.

Slowly fill the cooling system with a 50/50 coolant mixture until coolant runs freely out of bleeder screws.
Close the cooling system bleeder screws
Install the coolant pressure cap
Start the engine.
Run the engine at 2,000 - 2,500 RPM until the engine reaches normal operating temperature. (midway on gauge)
Allow the engine to idle for 3 minutes.
Shut the engine off.
Allow the engine to completely cool.
Top off the coolant as necessary.
Run engine again at 2000 - 2500 RPM until the engine reaches normal operating temperature.
Allow engine to idle until cooling fans come on. It should come on with the gauge about 3/4 of the way to red. - if it gets to where is touches the red, shut down immediately.
When the fan comes on, put your hand behind the fan and observe the temperature of the air coming from the fan. It should feel hot. If it is blowing cold air, the coolant is not circulating through the radiator like it should. This could be caused by lots of things including an improper/defective thermostat, corroded water pump impeller, or a blown head gasket.

Perhaps your gauge is faulty. Is your coolant filled up? You may also have a vapour lock causing the problem. Also you may have to change your thermostat. It may be sticking. Good luck!

It may be running because the engine hasn't cooled down. These fans will run until the engine reaches a specific cool temp. But if it's not running hotter than normal temp, it's within the temp switch, which reads the temp of the engine, or the relay could be bad and not know when to shut down. While you're driving look to see what the temp gauge is reading. This will lead you in different direction for the temp. switch.

Please do not drive your car until you can check a few things.

To answer your question...your car is hot while sitting at a light, but not when driving because of air movement. Think of it like like this...if you are standing in front of a fan, you feel cooler. If you step away from the fan, it will be warmer.

Back to your car troubles...you most likely are low on antifreeze. Please check the radiator for how much antifreeze you have. You will want to fill the radiator to the cap. If it has been this way for a while, you will have air in the line. After running the car for a while (after the fans turn on) add more antifreeze. It will most likely will show a lower amount.

Hope this helps.

Radiator fan is supposed to start working after the temp reaches a certain limit. And it is supposed to run til the temp reaches a certain lower limit. So when you switch off the engine and walk off the fans must be running to cool the water to that lower limit. Unless you seen that it runs well past that and does not stop at all. Does it start running when you start the engine? And runs throughout the time the car is running, which it should not. The relay seems to be out. It is this relay that controls the running of the fan. or the temp gauge. If the temp gauge is giving wrong temp then the relay has to keep working. Please check both, the relay and before that the temp gauge.

Hi dakota_love what we need to verify is if your cooling fan is operating properly, what you need to do is first bring temperature close to redline
(but don't hit redline it may cause a blown head gasket) than you need to open up the hood with the engine running (and temperature close to redline)at and see if any of the cooling fan in front of the radiator is coming on, please update once this part of diag. is completed so we know which way to direct for further diagnostic.
