Sounds like the radiator cooling fan is not operating. LIft the hood and let the car idle. At about the same time the top rubber hose from the engine to the radiator becomes hot the fan should come on. Check the fan fuse, fan motor relay and also the temperature sensor in the engine. Finally check the fan motor has not seized and that the motor still works (put 12volts across it). The car cools when on the move as air pushing through the radiator due the motion has a cooling effect

I have a Hyundai Santa Fe 2001 when it is sitting still and running it runs hot but when you drive it down the road it cools off what causes it


Fan/s not coming on when needed. When moving down the road the airflows over radiator cooling off the engine as when sitting still it needs the fan/s to move air through the radiator.

Why does my 2002 millenia overheat when sitting idle


Could be your cooling fan not running. While the car is moving air is being pushed through the radiator, but when the car is still the fan is there to pull air into the radiator, if the fan is not running the car will heat up while sitting but cool back off when you are going down the road.

Over heating 2002 Aztek First mechanic we took it to: replaced intake manifold and water pump, flushed system because dex-cool coolant had caused damage. Still over heated. Same mechanic said it was the...


If the water pump and thermostat have been replaced and the system has been properly refilled and bled , the only thing left is the radiator. If coolant is not flowing through it properly , vehicle will run hot. If your car has overheated to the point of boiling over , your new thermostat may now be damaged again.. As for the fans , they only come on when the coolant reaches a certain temprature. Under normal driving conditions , they would not need to come on while the vehicle is moving , as the air flow from driving down the road would be enough to cool the engine.

I have heat in my 2001 ford exploer when idle not when moving down road


Hello Lions.
Your Explorer has a stuck open thermostat.
When sitting there is little to no air flowing through the radiator.
As you start moving it creates airflow through the rad and cools it.
Replace the thermostat and you will have heat again.

Thank you for using FixYa.

Antifreeze is full? If you are moving down the road and it overheats it isnt the fan. The fan only cools the engine when the vehicle is sitting still.

Heat/Cool gauge fluctuates inconsistently


You might check the coolant level after the engine cools,if it's low add 50/50 mixture of coolant and water. Keep an eye on the level to see if it happens again. You might have a small leak in the system. Good luck

97 GMC Safari Van - Heater takes forever to blow hot air. Could this be a thermostat problem?


Hello,

Humm I make the assumption that you don't have overheating problems. Yes, sounds like a thermostat is stuck open. If you have a gage on the dash you may also notice that the engine temp takes a long time also. Sometimes when you sit a light for a while the temp edges up and starts to get warm....then when moving down the road a higher speeds the temp cools off again. this does this because the thermostat may be stuck open and it cools the heated water in the engine when moving. Also, check the coolant level in the radiator. (only do this when cold!!!!!!!!) ok????? NOT HOT! low coolant can affect how the heater performs. (low volume)

Hope this helped. :)
