If a Hyundai Elantra stops running after an hour on a running speed temperature, it could be a bad thermostat. It is best to have a mechanic take a look at it to determine the exact cause.
Bad temperature sensor unit? Cooling fan not working? Water pump not circulating coolant? Radiator plugged or restricted? System airbound? Thermostat not opening?
on the drivers side of the engine. you need to remove air box then the hose that connects to thermostat. Still stumped? run your car until its at running temp. Then carefully touch radiator hoses. follow the colder hose to the engine and your there.
it is probably the thermostat any one can change one on a Hyundai they cost under $15.00
Debris in the hoses or reservoir could cause the motor to overheat. Also, running the pump without fluid could do the same.
change the radiator cap. Did you check the water pump to see if it is pumping correctly? Did you check the cooling fan for proper operation? Did you bleed all air from the cooling system after adding fresh coolant. Did you install the thermostat correctly, (Spring down)? And lastly, does it possibly have a blown head gasket? I put this in my Watch List, and will await you reply.
Just go to your local auto parts store, make sure to know your make model and year. Engine size won't hurt either all though i think Hyundai has been running the same engine for a while.
im having the same problem with my 2000 elantra! after looking around on the internet im pretty confident its the crankshaft sensor.
My best guess would be for the parking break. Easy way to test, when the car is running just pull the lever or step on the lever and see what light turns on
there is a pipe running along side of inner wing on the Drivers side this is the ac pipe, halfway along toward windscreen there is a valve on top of pipe usually with a green cap on it, that is where freon goes..
Burning oil in the combustion chamber.AnswerNo worries, mine does the same thing. Just try switching to a thicker oil and check regularly.
It is important to know the symptoms of a bad car part. The symptoms of a coil going bad would be having a trouble starting and running the car, the coil getting hot, and poor fuel economy.
because the air condition is cooling the air! The colder air gets, the less water it can keep. So the water drips out of the box, where the air is cooled.
A bad relay in the fan's circuit could cause this. I have a 94 Hyundai Scoupe and I just had to replace the thermo switch attached at the bottom of the radiator. Had the same problem. Fan wouldn't go off....ever.
a mi me paso eso se arregla con solo cambiar el relay de luces y punto ya vuelve las luces a prender....
Possible cause is the crankshaft position sensor if you have a bad alternator then your battery can drain while the car is running DOn't know when did you changed cables lately but arching on one of them will do that. Check the cables for any damage or wear. Also look at distributor while you're there.
Just flushing the radiator, no but to flush the system, yes.
If your radiator is leaking then you will need to replace it. Additionally, if you find that your car is constantly running hot you will need a new radiator.
you can get some by running a lap around your house 50 times or more nonstop.
For a short time, No. It will just make steering a little more difficult. It will probably never actually hurt the car but could eventually cause damage to the power steering pump on some cars.
When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.
maybe my radiator is defective
first turn on the car and add the water to the radiator while the engine is running-- this allows the water pump to work and force the water to all the thirsty parts this will help the radiator and the crankcase fill much faster
No! At least mine don't
Make sure all cooling fans around radiator and condenser are running with a/c on and engine running at operating temperature. If ok then most likely cause would be low coolant level or restricted( clogged) radiator. My sisters 91 did the same thing two years ago and it took a new radiator to fix it.
