Question about 2003 Hyundai Tiburon

1 Answer

Car never reaches operating temperature (cold weather) thus little to no heat inside

I have a 1996 Ford Taurus and the radiator fans run constantly once they start and I get heat inside the car (during cold weather) for just a few minutes (before the radiator fans start). The temperature gauge on the dash stays near cold

Change the thermostat, sounds like it could stuck open and wont allow the engine reach operating temp, also test the constant control relay module located to the right of the battery as your facing the front of the car, also test coolant temp switch it might be defective and producing a high voltage that would cause the fans to constantly operate no matter the temp. Hope this helps

SOURCE: 1994 Hyundai Excel Air conditioning RADIATORĀ“S FAN works always very fast

this not really a problem as the fan speed is controlled by the high preasure switch in the ac system the hotter it is outside the higher the preassure will be in the system as hot as its been the preasure is high already when the compressor cycles it pulls suction on one side and outputs high preasure on the other the fans cool the condenser the higher the ambient temp the faster they go so all is fine...

If the water bubbles in the resevoir when the engine is running, the head gasket could be blown. There is often white smoke (steam) coming from the exhaust.

SOURCE: engine runs hotter than normal..lower radiator hose stays cold...

you could have air in the cooling system. look for a bleeder screw in a small coolant line.

Mitsubishi shogun 1998 model 2.8 over heating no leeks water is blowing back into the overflow bottle when hot


How are you sure it is overheating? Temp gauge? Most likely are stuck thermostat, bad fan thermostat switch, bad fan. bad head gasket. Coolant going into overflow when hot is how that system is suppose to work. As it cools, fluid is drawn back into radiator. It it is not really overheating, bad radiator cap can allow coolant into reservoir more than normal.

Change the sensor. Check the electric cooling fans and Relays. Some fans have 2 speeds and may not kick into high speed.
The radiator operates more or less closely to the block temperature. A Laser thermometer would tell you what the operating temperature is.

Where is the coolant bleeder on a 1998 ford taurus 3.0 engine


You can bleed the system of air by removing the radiator cap while the engine is cold. Turn the heater on high and let the vehicle run until it reaches operating temperature. The thermostat will open several times and purge the system of air. Feel the top radiator hose occasionally until it heats up. Don't forget to replace the radiator cap.

Ford taurus dpfe sensor hose blowing off


I have to put thus little bit of info in here. I just had to deal with an 02 Taurus that would not start. Managed to get it to start by holding the gas pedal to the floor and when it finally fired up it blew the DPFE hose off. After a while of it sitting in the garage I decided I would just keep the gas floored and after a few seconds it came around. My suspicion is that because this car only runs for a few minutes at a time, moisture accumulated in the CAT and froze when temperatures got into the single digits. My conclusion is make sure the vehicle get to operating temperature during cold weather to prevent exhaust freeze-up.

No heat for me and my daughter 201 ford taurs everything you can think of has been done to this car please help


i hate no heat. ford taurus 2001 are a problem sometimes with heat issues.on the firewall there are heater hoses that get clogged,pinched,and sometimes it's just a bad heater core. you said everything you can think of has been done?[replaced heater core? flushed the radiator? are the cooling fans coming on? is radiator full of coolant? have you took the cap off to be sure?like i said,i hate no heat. i'm still thinking.thermostat new?the blower works but only blows cold air?ok if thermostats good,radiator is full,blower works,radiators full,cooling fans coming on, no engine overheating but temperature is fine,let's do this for a short winter time solution only!in the front of your car with the hood up.look at the radiator,ok,in front of the radiator,place a peice of cardboard in front of radiator on the bumper side. think i'm crazy right? try this. cut just a small peice of cardboard about half the size of the radiator and insert it in FRONT BUMPER SIDE of the radiator, this will give you emegency heat,it will have to come out when the temperature outside warms up because it will make your car overheat.for sure.but in cold weather,it's a sure thing to bring the heat up inside the car. you are restricting the air that flows through your radiator while the cars moving down the road,do not let car idle as it will heat up,as long as you're moving you will be safe,keep an eye on your temp. guage as you may have to make an adjustment to the size of the cardboard. yep i was a truck driver for many years and know so well how cold the road is. i kept my cardboard handy in the winter and never got cold. you do have an existing problem with your heat,and unless you deal with it soon,you'll need those cardboard boxes and duct tape for a minute.if you don't beleive me,try it.you'll be toasty in no time,just watch that temp guage and you'll be fine. thank you for choosing fixya.com and by the way,let me know how it works for you,i love to hear that i've assisted someone,somewhere.

Replace the thermostat. I have had bad luck with aftermarket thermostats on this particular year of GM/ Chevy trucks.They tend to stick closed and then fully open, thus causing the temp to sort of surge hot and cold. A good thermostat will slowly open maintaning a good consistant temp. I would recommend spending a little more and getting a GM thermostat.

The heat on my 2000 Ford Taurus is not that good. Takes forever to heat up, but still not that good. Turning the fan up on high makes it worse. Best lukewarm heat is turning my switch to halfway on fan....


these cars are infamous for coolant contamination cause restrictions in the heater core. i suggest performing a heater core flush followed by a complete cooling system flush. i have seen this dozens of times in these cars and this has been the fix nearly every time. good luck!

My 2001 ford Taurus heating temp gauge is not constant on dashboard. It goes up and down. I don?t have heat. Water pump, thermostat, in and out pipe and coolant are changed. Still no heat.


Start the engine when cool, remove rad cap and start engine and let it run with the heater on. (not defrost) Top up coolant as needed in rad, and let it run until either the rad fan comes on and off 2 or 3 times, or you can see increased flow in rad from thermostat opening. It will obviously happen after it reaches operating temperature, so watch after gauge gets close to there. Wait until you see that flow 2 or 3 times or fan comes on and off before you put cap on, and fill return bottle to proper level as well. That should cure it, by getting air out of system, and coolant flowing through heater core.

1996 ford tarus location of coolant temperatue sensor?


I doubt if it is the temperature sensor if the gauge is working. Check to see if the fans are coming on when the engine is hot. The fans have two speeds and should come on in low speed and change to high speed as temperature gets hotter or when air conditioner is turned on. If they are working correctly. I would guess the radiator is partially plugged up between the air conditioner condensor and the radiator. These cars are bad about getting dirt, lint, and what ever trapped in this area.

Replace the engine thermostat, it is probably stuck open.

It is located where the top radiator hose enters the engine block and is supposed to close when the engine is cold, thus prevent coolant from going to the radiator while the engine is heating up.

At engine operating temperature, it opens up, sends the coolant to the rad, and keeps the engine coolant at that constant temperature.

99% of the time, this is the culprit.

The other 1% could be a clogged/partially clogged heater core, or a busted heater core (accompanied by a coolant leak/loss over time) which fogs up the windows even more when the heater is on defrost.

Thermostat replacement is an easy, quick job and cheap.

Heater core replacement is a little bit more time/money consuming
