Sounds like a defective coolant temperature sensor. You didn't tell us which engine is in your Santa Fe. 2.4 4cylinder, 2.7 V6? or the 3.5 V6?
Without diagnosing this problem myslef, there are several probable causes (first, coolant temp sensor), next could be wiring, ECM, welded contacts in cooling fan relay, short in relay circuit, etc.

Fan for radiador dont work only wend a/c is turn on fans come on but slow i gat a hyundai santa fe 2002


In general, vehicles with electric radiator fans use an electronic temperature control so the fans only run as fast as needed. The energy to drive the fans come from the fuel you burn, so this is supposed to improve fuel economy. The air conditioner load makes the engine run hotter, so the fans should come on then.

Now, here is the real question: is the engine overheating at traffic light stops? Do you see an abnormal temperature rise on the dashboard gauge (assuming you have one)? If so, you may have a problem with the fan motor bearing, check for smooth and easy rotation of the fan when the engine is cold (it's dangerous to do so when the engine hot; the fan may come on even with the engine turned off). On the other hand, if the temperature indication is generally lower than it used to be, the temperature sensor may be going bad and is not calling for the fan to be on when it should be.

2002 santa fe has no heat on heater


If the engine is reaching normal temp, and the cooling system is full of liquid coolant, you could have a blend door problem under the dash.

05 Santa Fe 3.5 overheat at idle,ok going down road. coolant level ok, fans ok.


hi, sounds like a clogged radiator, i have seen this problem in other hyundai cars, not on the santa fe though. if you have availibility to a large floor mounted or post mounted fan(just about any larger fan will work) put it in front of the radiator when it is over heating and see if the temp cools at all. there maybe either be something clogging the flow on the outside of the radiator, or possibly inside the radiator. The only other thing to check is the thermostat, stuck thermostats can go either way, stuck closed or open. or even partially open so as to restrict flow greatly. it would be a good idea to have it replaced no matter what you find actually causing the overheat condition. hope this helps.

The heat in my 2001 Santa Fe looks like works but the hat is not very hot, I did change the thermostast few weeks ago, the houses from the radiator get kind of warm but the heat inside the car is not hot...


you may have something plug in the heater hose themself and you may want to call around to see how much it will cost for a cooling system flush give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your SUV wish you the best of luck Michigan Man.

On my santa fe the heater wont turn on. I have


It could be your blower switch, but more than likely it's a resistor that is usually a part of the blower assembly, and it operates the speeds. Doesn't cost much but can be tricky installing. If you had one or two speeds not working, initially, eventually all may stop. If fan stopped working and all speeds had been operating, then you may have a bad wire or blower motor. Also, check your manual for fuses, as there may be a compartment inside the vehicle as well as one under the hood.

Boiling coolant hyundai santa fe


emma, how is the coolant level? Have you had to add any? Check the cooling fan(s) to make sure they are kicking on when the engine temperature rises. If they are not going on, check for a bad cooling fan switch.
